Michael DeBakey

Michael DeBakey (1908–2008) was an American cardiovascular surgeon whose innovations in vascular and heart surgery helped transform modern cardiovascular care.

Dacron graft: A woven or knitted polyester tube used to replace or reinforce damaged blood vessels. DeBakey helped establish synthetic grafts as practical replacements for diseased arteries.
Cardiopulmonary bypass: A technique that temporarily diverts blood through a machine for oxygenation and circulation during heart surgery. It made open-heart operations possible, a setting in which DeBakey developed and performed major procedures.
Denton Cooley: An American cardiac surgeon who pioneered open-heart operations and founded the Texas Heart Institute. Cooley trained and worked with DeBakey before their professional relationship became a celebrated rivalry.
National Library of Medicine: A United States institution that collects and provides access to biomedical information and historical collections. DeBakey's advocacy helped secure congressional support for the library's modern building.
Aortic aneurysm: An abnormal enlargement of the aorta caused by weakening of its wall. DeBakey developed influential operations for treating aneurysms of the aorta.
Roller pump: A pump that moves fluid through tubing by compressing it with rotating rollers. DeBakey designed a roller pump that became a standard component of heart-lung machines.
Adrian Kantrowitz: An American cardiac surgeon and biomedical innovator who developed early mechanical circulatory-support devices. His parallel work on heart pumps provides a direct contemporary comparison to DeBakey's engineering efforts.
Medical informatics: The application of information science and technology to health care and biomedical research. DeBakey championed using information technology to organize and distribute medical knowledge.
Coronary artery bypass surgery: An operation that routes blood around narrowed coronary arteries using a graft. His surgical work advanced operative treatment for coronary artery disease.
Heart-lung machine: A machine that temporarily performs the heart's pumping and the lungs' gas-exchange functions during surgery. His pump design helped make this apparatus practical for cardiac operations.
