Abstract

See full text

A cardiac valve prosthesis comprising an annular body housing a closure member in the form of two cusps. The cusps open and close freely and rotate simultaneously around the body axis, checking the forward and reverse blood flows through the prosthesis to simulate the operation of the cardiac valve. To have the operation of the prosthesis resemble that of the natural valve, the lateral surface of at least one cusp is provided with a recess to produce a controlled blood backflow through the prosthesis by causing the blood flow through the prosthesis to swirl.
