Using sound waves to destroy cancer | Christine Gibbons | TEDxDetroit


[Music]

good morning by show of hands which I

can’t really see how many out there have

seen Star Trek for the voyage home

okay well I’m sure you recall but the

crew time travels back to 1986 San

Francisco and in this scene here

dr. McCoy has to rescue check off from

the barbaric medicine of the 20th

century well I’m here today to talk to

you about some another person that’s

that’s wrestling with and struggling

with current modded modern-day medicine

her name is sue sue is a seamstress in

Barcelona she lives outside of the city

and takes the train to work she’s

married to her highschool sweetheart and

they have three children recently sue

has been having abdominal pains bouts of

nausea and vomiting and so she went to

her doctor he ran a battery of tests did

an MRI and she got that dreaded phone

call the diagnosis was cancer liver

cancer and so she met with her

oncologist and a surgeon and they

reviewed her case more bad news the

tumor was too large to be surgically

resected which meant she had heard the

the chances of long-term survival were

greatly diminished also the tumor was

located in a place that made it

difficult for this type of therapy where

large gauge needles are poked through

the abdomen to the tumor and the heat

then kills the tumor it was too close to

a vein so her doctor recommended

chemotherapy now sue knew that

chemotherapy would likely not cure her

but it most certainly make her feel

miserable for months to come I’d now

like to take you to the Future where sue

has the potential to be offered at

therapy that uses sound energy rather

than heat or incision or chemo to to

cure her and that and so talking about

then ultrasound ultrasound has been used

many to many for many years for imaging

but researchers have been trying ways to

use ultrasound

to create heat to destroy tissues

non-invasively well Charles Cain from

the University of Michigan was taking a

different path he was using wanted to

use the the sound energy to create

mechanical forces not heat to destroy

tissue he and his colleagues at the

University of Michigan Michigan actually

found that the mechanical forces of heat

could have great benefit as compared to

heat the mechanical forces excuse me of

sound they could use it to have great

benefits those mechanical forces could

actually be a lot more precise and they

have the potential for more rapid

healing quicker quicker recovery and

less pain so Charles and his colleagues

together with the university’s

technology transfer office licensed that

technology to a newly formed company

called histo Sonics and histah Sonic’s

got to work developing a medical device

that would be able to deliver histah

tripsy and the most important component

of that is the ultrasonic transducer in

the fundamental part of the ultrasonic

transducer is the piezo electric element

this one when electrical electricity is

applied to it vibrates and those

vibrations then create an ultrasonic

wave that can propagate through tissue

now by arranging an array of these

elements in a concave formation the

transducer then becomes capable of

transmitting ultrasonic waves that then

increases sharply in strength at the

focus by by pulsing those waves we

create the history of sea effect to

destroy tissue at the cellular level now

based on this principle the vortex rx is

being developed to provide physicians

the ability to non-invasively treat

tissue the transducer is placed over the

the target in this case a tumor in the

liver sound energy passes through the

body to those tissues creating an energy

field that creates bubbles then and the

expansion and collapse of those bubbles

is what mechanically then fraction

eights those tissues

now other therapeutic ultrasound

generates vibration

that then creates heat to destroy those

tissues which could then potentially

damage other tissues nearby not targeted

because of thermal spread with histah

trip see that pulsing is provided in

very very short pulses that allows then

a mechanical force and so that the range

of destruction of that tissue can be

precisely controlled and monitored in

real time the tissue then he gets

naturally absorbed in the body after the

treatment and the natural healthy cells

can regrow this is an MRI image after

histah tripsy treatment in a preclinical

model that dark circle there is the

treatment zone notice the precise

surgical like boundaries that we treated

where we wanted to and nowhere else

now imagine sue being offered this

therapy she would lie down at a table

the transducer placed over her abdomen

sound waves then generating in the into

the body

now her physician could see in real-time

that treatment effect because the

bubbles from his to trip sea are very

easily seen under ultrasound or MRI

visualization sue could then maybe not

even need general anesthesia the precise

targeted treatment of those tissues done

without incision and without needles now

this type of treatment then is brought

forward in our company histo sonics it

takes a very special team here’s a

picture of the team there’s me and my

co-founders Tom and Jim and our first

two employees Durant does Russell and

Dan that’s me with the blonde hair and I

love this picture because it was drawn

by Russell’s daughter Justine and it

along with other art created by art are

employed by the employees children grace

the alt the walls of our office at the

company and so that the cunt the team

here is driving this technology towards

patient care and it takes a very special

team as I said we’ve been able to

educate the medical device regulators

throughout the time this time frame

about the development of the device

itself as well as the technology

fundamentals we’ve had to create new

things and solve engineering challenges

we’ve also have to tell our story this

team tells the story a lot we tell the

story to potential clinical

collaborators we tell the story to

technology resources and we tell the

Technic the story to a lot of potential

investors we’re always ready to give a

pitch to a potential investor and when

pressed I even gave a pitch at my own

son’s wedding and when we tell this

story we hear lots of things some people

say that sounds like Star Trek this

could be benign and based on healing

device to replace barbaric medicine

others say that sounds like Star Trek

that’s too off in the future that’s

unrealistic and when we get that

feedback it’s very helpful to us because

it helps us remember sue and the

millions of others who suffer from the

the pains of barbaric medicine of today

it helps us to refine the story of our

message of the future of surgery and the

future of surgery is becoming a reality

right here in the Detroit area we expect

to treat our first patient early next

year

and so when we’re here today to share

positive ideas with the world from

Detroit and I’d like to say my pipe idea

besides fighting disease with sound is

to remember sue and dismember under

millions of others who have that feeling

of hopelessness because when we remember

them and those those who have the life

of life’s work in health care we

remember the ultimate reason why we do

what we do thank you [Applause]
