Abstract
A heart valve including a generally annular body and a disc within the body. A ring-like protuberance projects from one face of the disc, and a fulcrum member projecting into the central opening of the valve body engages the inner surface of the protuberance. The disc pivots about the fulcrum member, to open and close the valve, and fits loosely between the fulcrum member and retaining elements so that the disc can rotate in its own plane. The rig-like protuberance defines an abutment responsive to fluid flowing in the no-flow direction of the valve for aiding pivotal movement of the disc to close the valve. An upstanding continuous wall on the face of the disc opposite the protuberance responds to fluid flow in the flow direction of the valve for aiding the pivotal movement of the disc to open the valve. The fulcrum member carries a guide plate which cooperates with the free end of the fulcrum means for preventing movement of the disc in its own plane when the valve is closed.
