Inventors & Pioneers

Didier Lapeyre, M.D.

Inventor of the Triflo tri-leaflet cardiac valve prosthesis
Cardiovascular Surgeon with 45+ years experience in Cardiovascular Research
Scientific & Medical Advisor

Dr. Lapeyre has devoted his life to the design, development and validation of innovative medical devices for the primary benefit of patients.

He first worked on the first tri-leaflet heart valve in the 1980s with Dassault Aviation and led pre-clinical animal testing at the Texas Heart Institute.

Previously, Dr. Lapeyre served as designer and director of scientific and medical affairs for the total artificial heart research program initiated by Aerospatiale.

He also worked at the French Centre National de Recherche Scientifique (CNRS).

Dr. Lapeyre was taught by the pioneers of open heart surgery (Prof. Marion, Dr. Lillehei, Dr. Cooley, Dr. Frazier), and by the founders of artificial heart research (Dr. Pierce, Dr. Kolff and Dr. Akutsu).

He is the author of more than 30 scientific publications and is the author of more than 15 patents.

Philippe Perrier
