Lillehei-Kaster Pivoting Disk Heart Valve

Description (Brief)
This artificial heart valve was developed by engineer Robert Kaster (born 1933 ) and Dr. C. Walton Lillehei (1918-1999). Under Lellehei’s direction, Kaster made changes to an earlier design developed by Dr. Antonio Cruz.
The Lillehei-Kaster valve, clinically introduced in 1969, is a free-floating tilting disk heart valve. It is made with an inner titanium orifice ring with two small inner supports, and two lateral titanium struts extending from the support. The sewing ring is made of Teflon. By 1977 this valve had been implanted in 40,000 patients. The Lillehei-Kaster valve was manufactured by Medical Incorporated of Minneapolis, Minnesota.
