Dr. Donald Baim, a pioneering cardiologist who was chief medical and scientific officer of Boston Scientific Corp., died Friday after surgery to treat a form of cancer.

Baim, 60, had undergone surgery to remove diseased tissue caused by adrenal cancer, according to the Associated Press.

A former Harvard Medical School professor, Baim joined Natick, Mass.-based Boston Scientific in 2006, where he oversaw clinical studies, educational programs, physician relationships and device safety. An internationally recognized leader in interventional cardiology, Baim published nearly 300 scientific papers and edited a leading textbook in the field, served as a principal investigator in dozens of clinical trials and founded or consulted with more than 20 start-up companies and incubators.

In a statement to employees Friday, CEO Ray Elliott said, "we were fortunate to have had Dr. Baim as a member of the Boston Scientific family, and we are grateful for all he did for our company. He leaves us far too soon, and we will miss him very much."
