Yoav Medan, an Israeli doctor, has been working for the past
15 years on a new method of non-invasive surgery that combines two known
technologies into one operating procedure.
The idea of non-invasive surgery is not new. Non-invasive surgery has been used in various
treatments, in varying degrees of effectiveness for decades. The obstacle early
pioneers had in this area was not being able to see what was happening during
the surgery, and this resulted in surrounding tissue damage similar to the
damage seen in invasive surgery. Also,
the non-invasive surgeries were not effective because they could not properly
target the area on which to be operated.
Invasive surgery today is still risky and impacts patients for months
with pain, physical therapy, and medications. The revolutionary technique would
be finding a new effective treatment, without damaging surrounding tissues,
therefore maximizing the percentage of success while minimizing recovery times.
That’s exactly what this team of scientists has been able to accomplish. The use of Magnetic Resonance Imagining (MRI)
allows doctors to have real-time visual interaction during surgical
procedures. Focused ultrasound is used
today in procedures such as ones to break up kidney stones. Combining the use
of MRI and focused ultra sound, researchers at InSightec in Israel and partners
around the world, have created the ability to treat such ailments as motor
disorders, fibroid tumors, and metastases of the bone using this technique; to
be able to operate without damaging surrounding tissue damage and no recovery
time.

The operating room of the future could very well consist of
a surgeon sitting behind a computer clicking nothing more than a mouse. For example, a patient being treated for a
brain condition would be placed in the MRI chamber with a transducer placed on
their head. The MRI would pinpoint the
location and the transducer would project ultrasonic energy to the specific
area targeted by the surgeon. This
procedure could be compared to the process done to break up kidney stones,
doctors could change the amount of energy directed to an area from a brush of
air to a smashing force. The surgeon first locates the affected area by sending
a pulse that heats up the area a few degrees; this lets surgeons know if they
are focused precisely. Once the surgeon
has correctly focused on the affected area, he or she then sends the ultrasonic
pulse to that site. Patients can
literally walk away from this procedure in minutes, with proven relief.

John, a retired professor from Virginia suffered from
neurological tremors. Medicines were no
longer effective and his quality of life was poor and he was totally dependent
on others. Many patients are reluctant
to undergo traditional forms of surgery and physically cut into the brain. John underwent this experimental surgery in
early 2011, as approved by the FDAID at the University of Virginia. Here is a sample of John’s handwriting on
the morning of his surgery and hours after the procedure.
Many other patients have seen immediate relief with this type of treatment and their quality of life has been drastically improved. John is able to live an independent life and enjoys an active retirement life.

Many other patients have seen immediate relief with this type of treatment and their quality of life has been drastically improved. John is able to live an independent life and enjoys an active retirement life.
This technique could revolutionize surgery and already shows
promise in tackling different diseases, all while improving a patient’s quality
of life.

Israel really seems to be on the forefront of these medical technologies. I was just reading about a new cancer "vaccine" (used loosely) that targeted cancers which has metastasized. I wonder if this is a free-market result or a result of a government who is putting quite a bit of resources into helping an aging population?
ReplyDeleteMaybe consider exploring the economic impacts of some of these discoveries? What times/costs/risks does it take to get a technique or device to market?
