Starr-Edwards Silastic Ball Valve

In the early 1960’s, the Starr-Edwards valve became the first commercially available artificial heart valve. It was designed by engineer Lowell Edwards and Dr. Albert Starr. The Starr-Edwards valve underwent several modifications during 1960 through 1970 which resulted in several models which are no longer available. The current models, 1200, 1260 and 6120 have been unchanged since 1968.

The Starr-Edwards valve incorporates a metal cage surrounding a molded silicone rubber-derivative ball and a sewing ring containing silicone rubber and seamless cloth.
