ABSTRACT:
A prosthetic heart valve has a tubular valve housing, a suture ring, and a membrane-like gate supported within the housing. The flexible membrane is generally elliptical in shape and is fastened in the housing along half its periphery. Flexure of the membrane moves it between an open position which permits blood flow through the housing and a closed position which blocks the flow path of the housing.
