Biomedical engineering is a new, sprawling, and complex field, and were it not for the hospitality and patience of the more than 200 people I interviewed, I would never have been able to pull off this project. I am especially indebted to the ...

...medical engineering, or merely a very unhappy one, is open to debate. But one thing is certain. Were it not for the implantable cardiac defibrillator in his chest, Jay Joyce would lead a far different life, assuming he had one to live at all. A West Point graduate and former army officer who had completed Airborne Ranger training, Joyce was 46 years old when he discovered that ...
