I am a medical scientist, not a practical physician.

I am, in fact, a medical doctor; I am a world expert in mechanical heart technology; and I am an athletically fit man who takes care of his own health through diet and exercise, including frequent five mile runs.

As a medical doctor who chose a career in artificial heart technology rather than clinical practice, I decided not to take an internship, which is required for licensing. Instead, I work with invention, manufacturing, regulatory affairs, and clinical application of artificial hearts.

There is a clear matter that I am not a practicing physician; I have never been a practitioner; everybody has known for decades.

I am a medical scientist, not a practical physician. I think it's very upfront. I am a doctor. I have long experience with heart disease.

I do not practice clinical medicine and hence do not treat individual patients. My career is in medical science.

The artificial heart is very effective as a bridge to transplant, but the number of people that can be saved with human hearts is limited. A perfect artificial heart could save many more patients.
