What do clients have to say about you?

"I’ve had a very challenging 6 months. You were a constant source of guidance and support. The time you spent helping me and my family understand my diagnosis and treatment options made such a difference in my ability to move forward. we have all appreciated you incredible patience. I will always the way you cared for me as a model of how I will care for my patients--with limitless patience, kindness, and a sense of partnership."

"Just a note of thanks for the meticulous care you gave Tony during and after his operation. He has responded magnificently and continues to improve daily. Thanks to Dr Thomas, Tony received the greatest care throughout and we are most grateful."

What treatments are you most excited to offer?

My colleagues and I have built the Stroke Interventional Program, a superb stroke program, unique to the Boston medical community, which allows for the efficient transfer of patients to BIDMC where we have a dedicated team of stroke neurologists, interventionists, anesthesiologists and interventionsists to assess and treat stroke patients within the vital time frame of six to eight hours when intervention is of benefit

What’s your background, education and training?

The vascular method which uses the body’s blood vessels to carry these stem cells to the brain, appeals to me for two reasons. First, I believe it’s important to have another option to deliver stem cells to the brain. Secondly, the brain is a complex system, and the path through which directly injected cells travel through the brain is unpredictable.

I have also been involved in medical instrumentation design and innovation. A recent collaborative project with Harvard Engineering school to design a safer cranial drill won the Excellence in Medical Device Design Award from the Harvard School of Engineering and Applied Sciences and the Freduenstein/ General Motors Young Investigator Award. It also received a US patent. With George Verghese, PhD, from the Electrical Engineering Department of MIT, we are investigating the use of transcranial Dopplers to measure intracranial pressures noninvasively. This algorithm has already been validated in subarachnoid hemorrhage patients with ventricular drains.

What makes your business stand apart?

The clinicians at BIDMC really care for each patient on an individual level. The hospital always has the best interest of its patients on its mind—a fact which is evident in the amount of services that we provide: services that can be expensive to fund or do not necessarily generate money for the hospital but are nonetheless important. Studying the brain is challenging and what I consider to be the last frontier of medicine. Researching cell transplantation in spinal cord injuries was what sparked my initial interest in treating people with brain damage—there was just so much we didn’t know.

A stroke, aneurysm, or physical trauma results in brain damage when there is a loss of blood flow to cells causing portions of the brain to die. Researchers are studying how stem cells, which have the ability to grow into many different types of cells, can be used to regenerate or grow specific types of new cells. Right now, most research is focused on how to best inject stem cells directly into the brain in order to regenerate cells in the damaged areas. As an endovascular surgeon I’m researching an alternative method of stem cell delivery to the brain—by injecting cells in the arteries of the groin.
