In the US, UK and the European Union, the most common type of artificial heart valve is the bioprosthetic valve. Mechanical valves are more commonly used in Asia and Latin America. [citation needed] Companies that manufacture heart valves include Edwards Lifesciences, [5] Medtronic, [6] Abbott (St. Jude Medical), [7] CryoLife, [8] and LifeNet ...
In 1976, he founded St. Jude Medical where his team engineered the first bileaflet mechanical heart valve, which reduced the frequency of blood clots in patients. It still dominates the mechanical valve replacement market. [4] [5] In 1982, Villafana founded GV Medical, which developed a device to open blood vessels open. [6]
