MICHAEL WEISS-MALIK:
Hi, everybody.
-
Hear me OK?
-
OK.
-
So I think we're
going to get going.
-
My name's Michael Weiss-Malik.
-
Our guest today,
Jonathan Kuniholm.
-
I met him in, we
think, 2007 as far
-
as we can piece back together
at a SciFoo conference.
-
And he had some pretty
cool tech that he
-
was demoing on some open
source robotics stuff
-
related to prosthetics.
-
And I was impressed
enough that I said, hey,
-
you should come and give a
talk at Google some time.
-
And he took that to heart.
-
And about four or
five years later,
-
emailed me and said, hey, you
offer that talk at Google.
-
Now would be a great time.
-
So we're hosting him today.
-
Jonathan is the president and
founder of the Open Prosthetics
-
Project.
-
He's also a founder of
StumpworX, a startup that
-
focuses on prosthetic
technology.
-
He's also presidential appointee
to the National Council
-
on Disability.
-
And the stuff he has
to say is pretty cool.
-
So please put your
hands together
-
and help me welcome Jon.
-
(Applause)
-
JON KUNIHOLM: Thanks
very much, Michael.
-
Let me first just offer
a disclaimer with respect
-
to my government job.
-
They encourage us to do this.
-
That everything that
I'm going to say today
-
is-- are my personal
views and not
-
reflective of any position
of the government.
-
So what I would like
to talk about today
-
is, how we can design good
design to solve problems
-
that society has, for
the most part, neglected.
-
And I came across
one of those problems
-
personally after I
lost my arm in 2005
-
and discovered that
prosthetic arms were
-
an orphan medical device.
-
And in thinking
a little bit more
-
about why prosthetic arms lagged
so far behind other technology
-
that we use every day,
I started to realize
-
that prosthetic arms and
orphan medical devices
-
are part of a larger
group of those problems
-
that society has
tended to neglect
-
which can be solved by
something that we're beginning
-
to call public interest design.
-
And the question
that I'd really like
-
to talk about today--
and I would actually
-
like it to be the
beginning of the discussion
-
because it's something
that, by no means,
-
I claim to have
even begun to solve.
-
--is, how can we marshal all of
the tools at our disposal to,
-
trying to better
solve those problems.
-
Because very much now I believe
that most of those problems
-
are solved in kind
of a haphazard way.
-
Government-funded projects,
philanthropy, side
-
projects from industry,
you name the way
-
that people happen upon these
issues and try to solve them.
-
But in general, you can
be sure that the resources
-
and attention that we
devote toward solving
-
these underserved
needs are going
-
to lag far behind
those problems which
-
are very obvious from every
other standpoint need solving,
-
very profitable things.
-
There was no question
that cellphone technology
-
was going to improve over the
last 10 years, for example.
-
So in the summer of 2005, I
took leave from graduate school
-
at Duke University.
-
And I was deployed as a Marine
to Iraq in Anbar Province.
-
And I was the platoon commander
for an engineer platoon
-
of 50 Marines.
-
And we were doing
mostly what everybody
-
was doing over there which
is sustainment and stability
-
operations, patrolling, guarding
convoys, that sort of thing.
-
On New Year's today
of 2005, I was
-
on a foot patrol
that was ambushed
-
by improvised explosive device.
-
And the blast took off
most of my forearm.
-
And I found myself back
in the States and learning
-
about prosthetic arm technology.
-
I managed to get
myself back to school
-
and get involved with a
research project sponsored
-
by DARPA called the
Revolutionizing Prosthetics
-
2009 Project.
-
It was one of two that DARPA
was funding which is really
-
the first serious prosthetic
arm research effort that
-
at occurred in the United
States since-- there was
-
a small one in the '70s but
really since World War II.
-
And the goal was a
really ambitious one.
-
The goal was to
create in four years
-
in 2007 an arm using
commercially-available
-
technology that could go to
market in that year, in 2007.
-
And then, more
ambitiously, to create
-
an arm that had more
degrees of freedom,
-
was fully neurally integrated.
-
So nearly the same articulation
as a native human arm
-
and full strength.
-
And an incredibly
ambitious project.
-
What I think is
important to understand,
-
there's been an enormous-- and
this picture is up here not
-
too brag that I
was on "60 Minutes"
-
but to show the
kind of attention
-
that these projects got.
-
For whatever reason,
prosthetic arms
-
tend to really capture
the popular imagination.
-
People love robotics.
-
They love thinking about the
barriers, the singularity
-
and the barriers between man
and machine disappearing.
-
And it becomes a vehicle for
all kinds of philosophical
-
and science fiction interest.
-
I think the takeaway
about these projects which
-
is important to remember
is, first of all,
-
that we-- despite the
amazing things that both
-
of these research
efforts accomplished,
-
we still have not, 10
years, more than 10 years
-
since the war began Afghanistan,
actually pushing 15 now
-
--still do not have any
commercially-available device
-
that has resulted from any
of this government-funded
-
research.
-
We're still waiting
for the first one.
-
It has remained, as always,
just around the corner.
-
And I'm told that we're waiting
on FDA approval for the DECA RP
-
'07 project to
receive FDA approval.
-
And it has been in
some clinical trials.
-
But we still haven't
seen a device.
-
The other one is-- I think
that's important to understand.
-
It's my belief that
we have a media bias.
-
It's not a political
conservative media bias.
-
But it's one towards
entertainment.
-
And so there-- the word
bionic is used a lot.
-
The words dexterous
and manipulation
-
are also used a lot which
have very specific meanings
-
in robotics.
-
And there are some
caveats that I could give.
-
You could call a trigger
grip, for example,
-
where one part of
the hand is grasping
-
a handle of a cordless
drill, and the finger
-
is pulling the trigger.
-
That tends toward a
sort of manipulation.
-
It's at lease a compound grasp
where one part of your hand
-
is doing one thing
and one doing another.
-
But of course, the slide that
I'm showing here right now
-
gives you some insight into what
the human hands are capable of.
-
This pair of hands
is doing a card trick
-
where four cuts of the
deck are being controlled
-
by different parts
of the two hands.
-
And it's a dynamic movement.
-
And so I guarantee
you that there
-
isn't a robotic hand
of any kind that
-
could do these card
tricks right now.
-
But based on the popular press
presentation of all this,
-
you would think that it can.
-
You would think that
these problems are solved.
-
So while I think it's important
to acknowledge the strides that
-
were made by these
research projects,
-
it's also very
important to understand
-
that we are not there yet.
-
And we do not have
bionic people.
-
And these hands are,
for most part right now,
-
I think that it would be fair
to say, at least in terms
-
of prosthetic control, that even
these highly articulated hands
-
are really only
capable of grasping.
-
And the difference between
grasping and manipulation,
-
you can use a Rubik's
cube to illustrate.
-
Manipulation is a
speed cuber solving
-
a Rubik's cube in a few minutes.
-
And grasping is not dropping it.
-
And grasping a Rubik's
cube is actually something
-
that I can do with
the hook that I
-
wear when I do wear a prosthetic
arm, which is the Dorrance
-
5x named after the guy
who patented it in 1912.
-
And you can see that since
then, it's evolved a little bit.
-
There's some rubber grip on
the fingers, a cigarette notch,
-
and I think it's
called a pen notch now.
-
But this remains, despite
everything that's happened,
-
the most used prosthetic
terminal device in America.
-
And were you to go to the
Myoelectric Conference
-
in New Brunswick in
Canada this August,
-
it would be a fair bet to make
that the majority of amputees
-
attending the conference, at
least the ones who weren't paid
-
to be there by a
prosthetic company,
-
would be wearing
one of these devices
-
and not any of the
robotic prosthetic hands
-
that are available.
-
The other thing that's
important to note about this
-
is that there's another
choice which actually beats
-
all of them which is the
one that I'm wearing today
-
which is nothing.
-
And about half of
all arm amputees
-
choose most times not to
wear a prosthesis at all.
-
And it's mostly because
of weight and comfort
-
in suspension.
-
And I'm going to talk about
that a little bit later.
-
So now, why is all of that?
-
This is by no means an
attack on any the folks
-
who were generous enough
to fund that project
-
and try to make some progress.
-
The real problem is
that there simply
-
isn't a market for these things.
-
The market for powered
arms is just barely noise
-
compared to these
other large markets.
-
And even though the government
has accomplished quite a bit
-
in some of these
research projects, what
-
we call the valley of death
which is the bridge that one
-
of these products must cross
in order to get from the lab
-
into becoming a clinical
product, is really significant.
-
And without a market to drive
further funding, that gap which
-
is estimated by
people in the industry
-
to be something like
90% of the R&D remaining
-
on a medical product once
a proof of principle device
-
is finished, there's just simply
nowhere for those resources
-
to come from and make it happen.
-
And so correspondingly,
the amount
-
of effort that's actually put
into solving this problem is
-
also very small, compared
to-- I cherry-picked
-
a few really large
government-sponsored
-
engineering projects.
-
Some of which have been compared
to the DARPA prosthetics
-
project.
-
This is all in 2006 dollars.
-
The Manhattan Project comes
in at over $20 billion,
-
the moon race over $120 billion,
and just the R&D for the Joint
-
Strike Fighter at
over $40 billion.
-
And so the $100
million, well more than
-
anybody had spent on prosthetic
arms in half a century.
-
The DARPA spend is basically
just noise compared to this.
-
And I would argue that the
task that they set out to solve
-
rivals some of these in
terms of the engineering
-
effort required.
-
It's a small project
instead of a large one.
-
But nevertheless, an enormous
portion of our brains,
-
for example, is devoted to
the control of our hands
-
in manipulations.
-
I don't know if
you all have ever
-
seen-- I don't have a
slide of it here here,
-
but the homunculus that neural
researchers use to represent,
-
they take a human figure and
adjust him proportionally,
-
based on the number
of nerve endings
-
in some studies of the brain.
-
So this little figure has
gigantic lips, gigantic hands,
-
and, depending on whether you're
looking at the censored version
-
or not, gigantic
genitalia, reflecting
-
how much of our
brains are devoted
-
to control these various
parts of our body.
-
And this is true both in
terms of motor control
-
and sensory control.
-
I works both ways.
-
And as you can see from that
slide of the card trick,
-
feedback, sensory
feedback is certainly
-
a huge part of our hands
being able to do what we do.
-
So what we have is a
three-way market failure
-
to solve this problem- Industry,
government, and academia.
-
All doing their parts, but all
unable to solve this problem.
-
And so -- so
-
But of course, it's
completely understandable.
-
And that's why we
call a prosthetic arms
-
an orphan device.
-
The orphan drug law
that was passed in 1983
-
defined patients in need of a
drug as being medical orphans
-
if their patient population
was less than 250,000.
-
So prosthetic arms
in the United States
-
are about, a couple
years ago, 43,000
-
so fewer than 50,000 patients
in the United States.
-
So that's 1/6 of the maximum
threshold for being an orphan.
-
Course, the orphan drug law
covers pharmaceuticals and not
-
medical devices.
-
So we don't have a companion
regulation or law or anything
-
that covers the creation
of medical devices.
-
And another peculiarity,
of course, of that
-
is, how we pay for medical
devices in the United States.
-
And I will get to that
a little bit later.
-
So as I mentioned before, all
of these medical orphans--
-
and the NIH-- and
this includes all
-
of the drug, the orphan drug
patient populations and others.
-
The NIH lists something like
10,000 orphaned conditions
-
on its website.
-
And because I happened to be
interested in prosthetic arms,
-
I searched for limb
absence, arm absence.
-
And so my particular
orphan condition
-
is actually not one of the ones
that's listed on that site.
-
So I would say that
there are probably more.
-
And so the question is-- and
this gets back to the graphs
-
that I showed before.
-
Because there's obviously
no market for it,
-
it doesn't necessarily
make sense.
-
I wouldn't argue, for example,
that it's a travesty that DARPA
-
didn't invest $100 billion into
solving this prosthetic arm
-
problem because the
same could be said
-
for any of these other orphans.
-
We simply can't
afford to do that
-
from a public health standpoint.
-
It's just not an effective
way to spend our resources.
-
So nevertheless,
feeling like this
-
is a problem that we'd
like for society to solve
-
and that it's not the only
one, this is the question.
-
How can we attacked
these problems
-
and solve some of them?
-
And it's clear that
we probably need
-
to think about them a little bit
different way than we are now.
-
My friend Chuck
Messer described this
-
as using your geek
powers for good.
-
The Cooper-Hewitt Design
Museum, in referencing
-
the 90% of the world
that doesn't benefit
-
from our consumer culture,
they had a design exhibit
-
several years ago called Design
for the Other 90% in reference
-
to that.
-
And there's another movement
here in the Bay Area.
-
For example, you have
a designer and engineer
-
named Ralf Hotchkiss
who makes a wheelchair.
-
Whirlwind Wheelchair
is their organization.
-
And they make appropriate
technology wheelchairs
-
that have larger balloon
tires on the front
-
to deal with uneven terrain
and broken sidewalks
-
that you're more
likely to encounter,
-
if there are sidewalks all, in
a lot of the developing world.
-
And they have a cool
model where they
-
try to set up factories as
a profitable businesses,
-
a social enterprise, to
manufacture this wheelchair
-
design in the area where
they might be used.
-
And this in contrast
to sometimes
-
what gets done in the
wheelchair space, for example,
-
is to send a kind of
rickety hospital wheelchair
-
over to that environment
where at last,
-
like a lot of medical
technology over there,
-
about 10 minutes
before it breaks.
-
And then, somebody has trouble
finding a part to fix it,
-
and it ends up getting junked.
-
So there's-- whereas I'm arguing
that prosthetic arm users
-
in the United States are
an underserved population,
-
they're not
disadvantaged, certainly,
-
to the same degree that patients
in the developing world are.
-
But all of these
patients are underserved
-
in some way or another.
-
So a good phrase
that's been used
-
to describe all of these
problems and the design
-
that we can use to
try to attack them
-
is public interest design,
design in the public interest.
-
And so really what
I'd like to talk
-
about is, what are
the ways besides-- I
-
will start off with
government-sponsored research
-
because that's a lot of
what's happening currently.
-
But what is our
whole quiver of tools
-
that we might use to try to
solve some of these problems?
-
And-- yeah.
-
Sorry about that.
-
So what are the
collection of tools
-
that we could use to try to
better solve these problems?
-
And I, like lots of
people do, I think
-
I'll probably come down on there
being some combination of all
-
of these that are necessary.
-
But just to brush over
them all, to begin
-
with government-sponsored
research and commercialization,
-
then DIY and the maker culture,
potentially an orphan device
-
law to service as a companion
to the orphan drug law
-
that we've had in this
country since 1983.
-
And then, what other
regulatory or policy changes
-
might be made under
our existing structure.
-
But by program managers
who fund, for example, some
-
of this government-sponsored
research, what things might
-
they do to try to raise the
impact of the research funding
-
that they're
currently giving out.
-
And then secondly, what can
we do in the private sector?
-
Are there ways that folks
in the private sector
-
might be able to
contribute in ways
-
that don't impact
their own bottom line?
-
And they can
potentially even have
-
a win-win in serving
these underserved folks.
-
So to start off with,
these are the three--
-
these are icons that represent
the three major engineering
-
research efforts that
I showed the funding
-
levels for- the moon
shot, at the atomic bomb,
-
and the Joint Strike Fighter.
-
And it's certainly clear
that there are some problems
-
that government has
to solve if they're
-
going to get it solved for us.
-
While we do have SpaceX in
a commercial space effort
-
right now, it only exists
because the government
-
is choosing to create
that capability.
-
And the funding's coming
from the government.
-
So that's an example, actually,
of spreading this stuff
-
around a little bit.
-
But it was clear that
sending a man to the moon
-
or building the bomb,
however you feel about
-
that having done, these
were certainly projects that
-
would never have happened
had not one of the largest
-
and wealthiest
governments in the world
-
decided that they were
going to make it happen.
-
And they happen
because, in at least two
-
in these cases, the first
two that I mentioned,
-
the results were non-negotiable.
-
We were going to
get to the moon,
-
no matter how much it costs
and how dangerous it was.
-
And those who were
in charge of the bomb
-
viewed it as a response
to an existential threat.
-
And that failure
was not an option.
-
It's probably-- the
government probably
-
would have spent anything
to achieve these ends.
-
Now, a lot of times,
some these very programs
-
and the other basic
science research
-
that the government
does are cited
-
as having intangible
benefits that spin off,
-
that we would be without were
it not for these other efforts.
-
And so Tang, Teflon,
and Velcro are three.
-
And there's actually
a myth-busting page
-
on NASA's website that I
have up there on the slide.
-
Says that, in fact, none
of these three products
-
were created by NASA
or NASA-funded research
-
although the space program did
take advantage of all of those.
-
So while they used Tang,
Teflon, and Velcro,
-
they did not create it.
-
And I would argue that even
if they had, building a bomb,
-
sending somebody to the moon,
or building a high-tech fighter
-
jet are not the most efficient
ways to create things
-
like Tang, Teflon, and Velcro.
-
So if what you want
is a prosthetic arm
-
or to put somebody on the moon
or to build a fighter jet,
-
that is what you do.
-
And this really comes
down to a difference
-
between engineering
and basic science.
-
So the point is that
whatever efforts there
-
are that are devoted to
solving this problem,
-
it really needs to be dedicated
to solving the problem.
-
And there needs to be
some agreement on actually
-
what the problem is.
-
A significant component
of at least the four year
-
DARPA effort was based on the
creation of a neural brain
-
machine interface.
-
And it is-- well,
in the long term,
-
it's certainly true that
that represents potentially
-
a holy grail of prosthetic arms.
-
It's not clear that that is
a necessary component of it,
-
particularly given the state
of the technology that most
-
people are using every day.
-
So then-- so I was-- at the
time when I met Michael in 2007,
-
we had a version of
this hardware board
-
that we were showing
Google SciFoo.
-
And this is-- Tim Hanson
is now post-doc at UCSF.
-
And he created, when he
was at the Nicolelis Lab
-
at Duke University, the
signal processing board which
-
is capable of processing 16
EMG, electromyogram, signals
-
from the surface
of the skin that
-
can detect muscle movements.
-
And we designed it to have as
many interfaces as possible.
-
Because are our goal
in this DIY space
-
was to try to encourage
experimentation
-
and to try to benefit
from the maker
-
culture and the huge
video game industry in --
-
And hope that some of
those resources and efforts
-
and interests could rub off
and make some improvements
-
in prosthetic arms.
-
What we learned is the
downside to DIY maker
-
and open source culture was
that, these projects sometimes
-
require-- well first, they
can't be done completely
-
without resources.
-
And then secondly,
there's activation energy
-
to any kind of
collaborative effort.
-
Which if you don't
cross, you have
-
a lot of difficulty
making anything happen.
-
So this project is still alive.
-
I looked.
-
There were commits this week.
-
But they're primarily-- but all
of those, as far as I'm aware,
-
are coming from the two
labs at UCSF and Duke
-
that are using the hardware.
-
So the schematics-- all
this is open source and GPL
-
to the extent that it
actually applies to all of it.
-
The schematics are up there,
all of the masks, the firmware
-
for the board,
everything is there.
-
But as far as I'm aware, nobody
has actually made one of these,
-
except for those two
labs that are using
-
and are active contributors.
-
And Tim made a pretty
complicated board.
-
It's like six layers and has
these tiny little vias and some
-
04 components on it.
-
We had some-- we made
this thing in a toaster
-
and had some horrible moments
where somebody breathed on it
-
or-- And then, you can't
tell what any of those things
-
are anymore, et cetera.
-
So as far as I know, nobody from
the larger DIY or maker culture
-
has participated
in this project.
-
Now, there's also-- there's
another part of the project.
-
We have functioning pattern
recognition software in MATLAB
-
which is not open source.
-
And again, this is
another barrier.
-
In order to use the open source
software that we have up there,
-
you need to have
access to something
-
like $20,000 worth
of MATLAB tool boxes
-
which you're only going to have
if you're either an industry
-
or you're in academia somewhere.
-
So these, again, are
some of the barriers.
-
But beyond that,
this hasn't really
-
had the impact
that we really hope
-
that it would have
when we started.
-
Although I'm certainly
proud we tried,
-
and it's a pretty cool
piece of hardware.
-
Here's another one.
-
We had a little project on
the open prosthetics project
-
to recreate a
prosthetic hook that
-
was designed in the '20s which
has been out of production
-
for something like
35 or 40 years.
-
And most of the guys,
and it is mostly
-
guys, who use this hook
are now 80, 90 years old.
-
And I live in the Midwest.
-
I think there are some
demographic particular areas
-
about where this
thing was prescribed
-
or what people
wanted to use it for.
-
And I still get calls from
people who find-- very few,
-
it's a trickle.
-
--who find this thing
on the web and want one.
-
And you can see here, this
is a picture-- somebody,
-
Bre Pettis put it
in the Thingiverse.
-
And a bunch of
people-- I got bunches
-
of people who want to volunteer.
-
They were offering to print
as many of these things
-
as they could on there first
generation MakerBots, which
-
is where I think this
printed hook came from,
-
to help the project.
-
But unfortunately, even
the latest generation
-
MakerBot 2-- which which
I have and really enjoy.
-
--it doesn't print
in a material that's
-
appropriate for actual use,
at least in this design.
-
This is made to be a
metal, a metal hook.
-
And you can see that the
resolution is really not
-
fantastic there.
-
So and what we discovered,
that one in the lower right
-
was printed using
a selective laser
-
centering rapid
prototyping process.
-
And we had some tolerance
problems with that
-
until the service bureau
actually printed the thing out
-
on a plate and then
machined off the plate.
-
The two jaws of the hook
did not fit together.
-
So we had something like more
than 50,000ths off on that
-
thing.
-
and.
-
I bring this up
just to point out
-
the limitations of
some of these things.
-
And you see this--
just a loop back
-
for a moment to the
breathless enthusiasm
-
of the press for a
lot of these things.
-
I can't tell you the
number of stories
-
that I've seen in
the last two years
-
about a high school
student who has 3D printed
-
a prosthetic hand that is
supposedly better than, you
-
pick the price point, of
some commercially-available
-
prosthetic hand.
-
And when you-- there's
really no scrutiny
-
at all that's applied
to these claims.
-
Very often, there are
completely externally-powered.
-
Like motors with strings or
maybe they're not even powered.
-
In any case, nobody really
closely examines the claim
-
that some kid has bested
a $40,000 prosthetic
-
hand in his bedroom
with a RepRap machine.
-
And while I consider
myself to be a part of
-
and fully embrace
the maker culture,
-
I think we also need to be
very realistic about what we've
-
actually accomplished
and try not
-
to run victory laps before
we've actually done it.
-
And I think that this probably
is one of those cases.
-
Now, the happy
ending to this story
-
is that there actually is
a prosthetic company called
-
ToughWare that re-engineer--
they re-engineered this
-
and fixed some of the
problems that we had actually
-
identified with the
original design.
-
I think you could
actually see it
-
in the-- that's an original hook
from many decades ago up there.
-
And you can see the
places it has been welded.
-
And so this company fixed
some of the problems
-
and where these
things were breaking.
-
And I do believe that
you can actually now
-
purchase a version of this
hook commercially again.
-
So I consider that
to be a success even
-
if we weren't the
ones who did it.
-
So lastly-- and there is
some bleed across here.
-
Michael did reference the
company that I've started.
-
I also decided to
back up a little bit
-
and solve one of the problems
about prosthetic arms that
-
may be, in fact, the most
vexing and least address,
-
which is how we attach
them to people's bodies.
-
This is traditionally done
with a hard carbon fiber
-
or fiberglass socket,
a rubber liner,
-
and maybe a plastic
socket there.
-
And I would liken a
lot of these designs
-
to wearing wooden
shoes and rubber socks.
-
And it does pretty horrible
things to your skin
-
when there's moisture
and friction involved.
-
And heat, moisture, weight,
and perceived weight
-
is really related to
all of these things
-
because people will tolerate
hanging less off of your body
-
when it doesn't really fit well.
-
It feels like it's heavier
if it's uncomfortable.
-
So we decided that
the way to solve this
-
was to go back to what
prosthetic arms used
-
to be like in the
'40s before the VA did
-
all the research that created
these composite sockets.
-
And consider making prosthetics
sockets more like shoes,
-
like athletic shoes.
-
Prosthetics sockets used
to be made of leather.
-
And I've been told
by old guys who
-
wear leather
sockets that they're
-
the most comfortable
thing in the world.
-
And they'd never
wear anything else.
-
But you can't find anybody
to make one of these things
-
now because they're
really labor intensive.
-
And the VA actually did
a whole bunch of research
-
in the '40s, trying
to figure out
-
how to make them not stink
because of they're basically
-
like shoes.
-
So we now have a pending
research proposal
-
that we should hear
from the Army and DARPA
-
from any day now to use current
athletic shoe technology to try
-
to make a flexible, variable
compliance socket that's
-
stiff in some places
and flexible and others,
-
breathable everywhere.
-
That basically solves
all the same problems
-
that your running shoes do.
-
And this would address
the number one reason
-
that people abandon
prosthetic arms.
-
And that, by the way, actually
includes, for example,
-
one of the DARPA arms that
was tested in VA clinics
-
among transradial
patients like me.
-
Comfort was actually
one of the major reasons
-
that I think about
half of those patients
-
said that they might not
be interested in having
-
one of those new arms.
-
So if we solve that
problem, then we
-
could potentially make a
lot of the other technology
-
more effective because
we'll be better
-
at attaching it to
people's bodies.
-
So that's what we're
up to right now.
-
An orphan device law.
-
So at the time that the orphan
drug law was passed in 1983,
-
we had a bipartisan Congress.
-
And I think that to imagine
in the current legislative
-
environment that we
can get anything done,
-
may be over optimistic.
-
Although, perhaps,
in an ideal world,
-
we would consider a law that
could increase innovation
-
and competition in this space.
-
Now, for those of you who
are unfamiliar with it, what
-
the orphan drug law does is, it
extends exclusivity for a drug
-
company who has
developed a product
-
but who believes that
the further investment
-
necessary to actually bring
a proven drug to market
-
is not worth the investment
because their patent,
-
the exclusivity available to
them on the original patent,
-
has expired.
-
Drug development is often
a really long process.
-
And it's a race against
the sundown on the patents.
-
Now unfortunately,
I'm not convinced
-
that a similar model in the this
even much smaller orphan device
-
spaces would
actually do anything
-
because exclusivity in
prosthetic arm patents
-
is often abandoned
when people decide
-
to stop paying the maintenance
on their process arm patents
-
after seven or 15 years.
-
So they're leaving exclusivity
on the table with regard
-
to patents in the space already.
-
So would extending it
actually do anything?
-
And I'm not convinced
that it would.
-
So Yeah?
-
AUDIENCE: [INAUDIBLE].
-
JON KUNIHOLM: OK.
-
So since we're not
miked in the audience,
-
the question is, is the approval
process for medical devices,
-
prosthetic arm
specifically, similarly long
-
as it is for drugs.
-
That's sort of a
complicated question
-
because it depends on
which class of devices
-
you're talking about.
-
The FDA it has three classes
of medical devices- I, II,
-
and III.
-
The DARPA neural sensing
system would be a Class III
-
medical device
because it actually
-
involves an internal implant.
-
Most prosthetic devices
right now are Class I.
-
And they're not only
Class I, they're
-
Class I Exempt which means that
there are exempt from-- there's
-
something like seven or eight
requirements for Class I
-
devices.
-
And all but three
of those are ignored
-
for this group of
Class I Exempt devices.
-
So in fact-- and this
is something actually
-
that there's been some--
some of the folks who've
-
been pursuing these new
things have been assuming--
-
and they may be right.
--that the FDA is seeking
-
to regulate prosthetic arm
stuff more rigorously than they
-
have in the past.
-
So even though you
could bring-- there
-
are articulated
myoelectric hands
-
that have been brought to
market in the last five years
-
that were brought to market.
-
All you have to do basically
is announced to the FDA
-
that you're going to start
selling these things and do it.
-
And if you're going to test
it, you stamp it experimental.
-
And you're good to go.
-
But nobody wants to invest
hundreds of millions of dollars
-
in the creation of
a device unless they
-
are sure that they're going
to get away with that.
-
And the FDA had
been making noises
-
that they were going
to try to bump up
-
the classification of
some of these things.
-
And they also have a requirement
for orthopedic devices
-
which is reasonable.
-
It's based on-- so a screw
in an orthopedic implant
-
is a Class I device that's a
component of a Class III device
-
which is the implant.
-
And there was a bad
failure in the '80s because
-
of the changing of
these Class I devices.
-
And so the FDA requires
each Class I component
-
be separately recertified
with the Class III system.
-
And if somebody did something
like that, for example,
-
with, say, there's a bolt
that can go through your skin
-
into the bone.
-
It's called osseointegration.
-
A titanium bolt.
-
And the bolt, of course,
is a Class III device
-
because it goes inside the body.
-
And if they required you
to separately certify
-
every prosthetic hand
or foot that you attach
-
to one of these systems,
it would effectively
-
mean that there wouldn't be
any available because nobody
-
would bother to do it.
-
So the whole-- so actually, you
bring up a really great point
-
which is that the FDA is a
really important part of this.
-
And some orphan device law, a
hypothetical orphan device law
-
or revisions of regulations that
might really impact the space,
-
should try to remove
some of those barriers
-
that actually the
FDA could potentially
-
create in trying to
better protect us.
-
And there are humanitarian
exemptions available.
-
And so it's something
that I think
-
bares further consideration.
-
So that leads into
the next group
-
of things which
are beyond new law.
-
What about the interpretation of
existing laws and regulations?
-
The Bayh-Dole Act
is the law from 1980
-
that governs the
government-funded creation
-
of intellectual property.
-
And the part that most of us are
familiar with, if you've ever
-
received a government grant,
is that the government
-
has royalty-free nonexclusive
license to anything
-
that they pay you to create.
-
But then, in order to
encourage economic activity,
-
anybody who creates this
stuff has the permission
-
to go off and license it.
-
Do whatever they want, exploit
that intellectual property
-
on their own, as long as they
don't charge any royalties back
-
to the government.
-
In practice, I think some
of this actually goes on.
-
Because if they fund,
particularly weapon systems
-
and stuff like that, it's
not like they segment off
-
what the intellectual
property component of it is.
-
It's not like anybody else can
make some of these fighter jets
-
or tanks or whatever.
-
So the least popular
provision of this law
-
is what are called
march-in rights.
-
Which means that if the
government-- if there are--
-
there are four criteria
that could be met where
-
the government can
come in and say,
-
you are not making use of this
intellectual property the way
-
we intended you to.
-
We're going to take it from you
and give it to somebody else.
-
And people-- it has been
exercised very few times,
-
if ever.
-
And it's a very unpopular,
as you can imagine,
-
provision with people who get
a lot of government funding.
-
How much time do we have?
-
So while this law
exists, it is something
-
that could be made use of
that's on the books already.
-
And so people, program
managers could say, OK,
-
so it's been 15 years.
-
You haven't-- you created
a product where we're going
-
to find somebody who will
because our goal is to bring
-
something like this to market.
-
And another one that
I referenced earlier
-
is the Center for Medicare
and Medicaid Services.
-
So all these devices, and many
medical devices are like this,
-
are reimbursed as durable
medical equipment-
-
canes, walkers, CPAP machines,
and prosthetic devices.
-
And the weirdness
that this creates
-
is that the whole
cost of supporting
-
the device for something
like five years
-
in between replacements
has to be captured just
-
in the provision of the product
at the beginning of its life
-
cycle.
-
All of the appointment
and everything.
-
So a prosthetist needs to be
able to function based on that.
-
The other thing that's
weird about this
-
is that there's a perverse
incentive, of course,
-
to provide more
of these products.
-
Because if you give
somebody a myoelectric arm,
-
it reimburses at
$30,000, $35,000.
-
A body-powered
arm may be $8,000.
-
And the other thing is that the
way that these reimbursement
-
codes are created is
that a company has
-
to demonstrate efficacy.
-
And then, they petition CMS.
-
And so that they have to
basically outlay all of the R&D
-
ahead before they know
if they're going to get
-
reimbursed.
-
Then, there have been
some recent cases
-
where people get the wrong
answer back from CMS.
-
And it kills the company.
-
A good example is
the iBot wheelchair
-
which everybody agrees is
pretty impressive technology.
-
That came back as being
excluded to a very
-
few pretty serious
disabilities and not
-
reimbursable at a rate that
could sustain its manufacturer.
-
And the company has
closed it doors.
-
And so it's actually
up in the air
-
what's going to happen
to that technology.
-
Hopefully, DEKA, which
is the creator of it,
-
will figure something out.
-
So one thing that I
think people might do
-
would be to create incentives
in reimbursement codes.
-
You could create a code
for the performance
-
of a particular device without
knowing that it exists.
-
And so I could say, a 15 degree
of freedom prosthetic hand
-
and wrist that's capable of
all these performance criteria
-
will reimburse at this rate,
$150,000, whatever it is.
-
And then, a company
would know ahead of time
-
that they have a
payday ahead of them
-
if they're capable of
meeting the criteria.
-
And so it would be much more
clear that this was possible.
-
Then, contract language.
-
There's a bunch of open source
and open architectural language
-
that the Navy, for one,
still has on kind of dead
-
website that's still up there.
-
But it's sample program
manager language
-
to put in RFPs to
ensure that you
-
can get what you
want out of them.
-
And those are tools
that could be used.
-
And then lastly, the DARPA
has made really good use
-
of challenges and contests.
-
And I think this sort of thing,
in partnership with industry,
-
might be very helpful.
-
So I guess in some
sense, my graphic here
-
of somebody cutting
red tape, maybe
-
I'm actually talking
about creating
-
some more in some cases.
-
But you get the picture.
-
So what about industry?
-
And that's you guys
here at Google.
-
I think that Google has done
some really creative things
-
in terms of business model in
creating great products that
-
solve problems in ways
that people hadn't before
-
by focusing the
business model in sort
-
of unexpected parts of it.
-
And so I think both Android,
both the Android operating
-
system and Gmail are
good examples of that.
-
In a recent acquisition of
yours, the nest company that
-
makes these thermostats
and the smoke detector,
-
those are examples
of products where
-
people would have said
the innovation is--
-
these are commodities.
-
You can't improve on this.
-
It is what it is.
-
Everybody has to have one.
-
And you're going to buy
the $8.95 one instead
-
of the $9.95 one because it just
does whatever it needs to do.
-
And I think the way that that
company was able to really pay
-
attention to consumers
represents creative thinking
-
which is the way that
probably everybody needs
-
to attack challenging markets.
-
And these ones that
I've talked about
-
are certainly some of them.
-
So you guys have
also been in the news
-
recently for, by count,
something like nine,
-
counting the drone company,
robotic acquisitions
-
over the last year or so.
-
And one of these
is Redwood Robotics
-
which I think involves a part
of a Willow Garage spin-off.
-
And I looked a little
bit-- I'd never
-
seen this hand picture before.
-
It looks to me like a rendering.
-
I don't know if it
represents a real product.
-
I think that it's
interesting that, in terms
-
of a manipulation and
terminal device, a hand
-
acquisition that you
guys chose to acquire,
-
Redwood and not any
of the companies
-
that were involved in the
DARPA prosthetic arms,
-
the-- there's an interesting
companionship between robot
-
teleoperation and prosthetics.
-
Myron Diftler, who runs the
robonaut program for NASA
-
at Johnson Space Center, said
that when he thought about it,
-
the prosthetic
problem is basically
-
a teleoperation problem.
-
You just happened to be
attached to the device you're
-
trying to teleoperate.
-
So in some sense, when you
take away video latency
-
to the moon or whatever, the
prosthetic control problem
-
might be, in some sense, easier.
-
Although the way that
these things are usually
-
performed right now is
with a haptic armature.
-
And in the prosthetic
case, obviously, you're
-
trying to control a limb that's
absent, so you don't have
-
access to those
fingers to tell you,
-
to tell those digits
where to move.
-
Anyway, my point
in bringing this up
-
is that there is some
great companionship
-
to these problems.
-
And in fact, while
it is not clear
-
right now who in America is
ready to buy, for example,
-
a personal assistance
robot or some other things
-
that one might
imagine as products
-
that could come out of companies
like these down the road.
-
There are prosthetic
customers who
-
can, according to the
current reimbursement
-
system, in some
cases, pay in excess
-
of $100,000 for one
of these devices.
-
So it might be possible to
create a synergy of interest
-
where you're solving problems
for the future of home
-
and mass-produced
robotics at the same time
-
as you are serving prosthetic
customers in the near term.
-
Even though they don't represent
the huge revenue stream
-
that we all would if everybody
has a Jetsons-style maid
-
in their home.
-
This is a picture
of my friend Kevin
-
who was born without
both of his legs.
-
I throw his picture up there
because he is, in some ways,
-
represents an orphan of an even
smaller community than my own.
-
Without any hip joints, when
he was about 10 years old,
-
they tried to put
prosthetic legs on him.
-
And they weren't really
anything but another couple
-
of extra crutches for him
to sort of haul around.
-
And he very quickly decided
that he wanted no part of that.
-
And he gets around
on a skateboard.
-
Now, that said, if
you were to envision--
-
and that's a way to
stay active, too.
-
But if you were to envision a
robotic prosthetic device that
-
might help him, it
could look something
-
like Boston Robotics,
Boston Dynamics-- I forget
-
the name of the
company. --in Cambridge.
-
They have the big
dog, walking bot
-
and those others where they
pretty famously kicked them
-
over in the video.
-
A pair of those walking legs,
controlled like the Segway,
-
is by leaning, could
do a pretty fair bit
-
towards replacing legs.
-
And so that's another case where
one of these robotics companies
-
might hold, in currently
available technology, the keys
-
to making a change
in somebody's life.
-
And my hope in
mentioning industry--
-
and I think, again, none of
these are mutually exclusive.
-
I do believe that
the only way that we
-
are going to solve these
extremely vexing problems
-
to society is by throwing nearly
everything that we have at it
-
and seeing what sticks.
-
And so really my purpose
in talking to you today
-
is to try-- I want to start
this conversation because it's
-
pretty clear to me that there
are some things that we could
-
do better about how we're
responding to these problems.
-
And I'd very much like some help
in figuring out how to do it.
-
So I used up more time
than I had intended to.
-
But if you all
have any questions,
-
I'd certainly like to
try and answer them.
-
So the question is-- I mentioned
that most arm amputees still
-
use hooks vise the
more complicated
-
electrical externally-powered
prostheses and why.
-
I think cost is part of it.
-
The Affordable Care Act
has changed some of that.
-
Before January, a lot of
people with medical insurance
-
had lifetime caps of, in
some cases, just more,
-
like $1,500 lifetime cap on
prosthetics services which
-
isn't even enough to
get a single prosthesis.
-
And beyond the
expansion of coverage,
-
the removal of the lifetime
caps and pre-existing conditions
-
are huge for the
prosthetic community.
-
So to the extent
that it is monetary,
-
the Affordable Care Act
should change some of that.
-
I, anecdotally, I don't
think that there's
-
any great data on this.
-
But I think that a lot
of common complaints
-
about the myoelectric
prostheses are latencies,
-
unintended movements, the speed
with which the motors move,
-
the weight.
-
And then, I think you
hit on it, function
-
is probably the primary reason.
-
The hook has been famously
described in TED Talks
-
as a rubber band and a
hook on the end of a stick.
-
But I believe that
the bar is actually
-
quite a bit higher than that.
-
The Dorrance hook is really
kind of a marvel of design.
-
It's got a bunch of
affordances built into it.
-
You can pick something
up, use it as a hook,
-
and as a split hook,
you can open it up
-
and use the individual
fingers for different things.
-
The little thumb that
has the cable on it---
-
I'll put that back up.
-
The little thumb that
has the cable on it
-
can be used to push things.
-
And is the part of
the device that's
-
used to wedge a
knife and a fork.
-
Actually that's
a perfect example
-
is eating with a knife and fork.
-
With cosmetic coverings
on the myoelectric hands,
-
they tend to be slippery.
-
And it's hard to get a knife and
a fork to sit securely in them.
-
And this thing is designed
to do exactly that.
-
It's got a chisel
tang in the middle,
-
so you can stick
a tool in there.
-
Or you can wedge either
a knife or a fork
-
in between the fingers
and over the thumb.
-
So I think function
is a lot of it.
-
Any other questions?
-
Yeah?
-
AUDIENCE: [INAUDIBLE].
-
JON KUNIHOLM: Yeah.
-
So well, first of all,
it's selfish of me, right?
-
That's my problem.
-
So that's what I spend a
lot of time thinking about.
-
But there are other
complications.
-
So there are something like
50 times more leg amputees
-
in America than arm amputees
because of peripheral vascular
-
disease secondary diabetes.
-
And that's the major
cause of leg amputation.
-
So there are more than
two million leg amputees
-
in America.
-
And most of-- and is an
easier problem to solve, too.
-
When you're looking at--
well, Oscar Pistorius
-
is a great example.
-
The cheetah legs make somebody
capable of running close to 10
-
second 100.
-
Although knees are a problem.
-
And Oscar Pistorius is
a below knee amputee.
-
But then, among the
powered devices,
-
control engineers
who work on legs
-
have told me that it's possible
to do reasonable approximations
-
of gate with the individual
components not even talking
-
to each other.
-
Where they just respond
to the external forces,
-
and they're capable of doing
a pretty good job walking.
-
And contrast that to
an arm where just,
-
forget the manipulation
stuff, just
-
reach to grasp with a
whole arm for somebody
-
up to the shoulder level
involves the coordination
-
of all of the joints together.
-
So I like to say that if you
imagine that these are legs,
-
the arm problem has five of
them on the end of a sixth.
-
And they all have to
dance together in order
-
to do the most basic task
that an arm has to do.
-
Yeah.
-
And so the economics are--
legs are a lot bigger business.
-
So there is a real incentive.
-
Although there are
some new leg companies,
-
because of the high cost of
additional degrees of freedom,
-
there are some
leg companies that
-
are going to be in
trouble if they don't
-
get the reimbursements that
they want on powered ankles,
-
for example.
-
And so in that sense they
share exactly the same problem.
-
Anything else?
-
Any questions from our
remote rooms?
-
All right.
-
Well, listen.
-
Thank you very much for taking
the time to check it out.
-
And I don't if there's a way for
me to post contact information
-
or whatever.
-
But if anybody's interested
in further talking about this,
-
please get with
Michael Weiss-Malik.
-
And he'll put you
in touch with me.
-
Thanks very much.

Thank you so much for subtitling this video, Dennis. It's a long one - do you want to subtitle it alone, or would it be OK if others joined?
Dennis Au
No, definitely happy for others to join in. Pretty new to Amara, so I'm not sure what the normal process is for dividing up larger files.
I'm done for the night anyway, so very happy to have someone continue on from where I got up to. :)

Thanks, Dennis, so I did, but just a little bit for now because my connection is slow. I marked the point reach in the last sub - 12:58 - because it makes it easier to launch the video at the right point. I also added some "(check)" for bits I'm not sure of - they can wait until we do the syncing.
Best,
Claude

Hi, Connie and Dennis,
So now "Talks at Google" has captioned the original video: per se, that's great, but I hope you're not too peeved about the time you spent on the subtitles here? Sorry about that: they didn't use to caption these talks. I'll now upload their subtitles over ours: this way if people want to translate them, they can do it here.
Best,
Claude
