ABSTRACT:
Prosthetic heart valves having a single occluder, or a pair of identical mating occluders, guided in their movement from the open to the closed position by pairs of elongated slots in diametrically opposed flat sidewall sections of the valve body. Each occluder is formed with two ears that protrude from opposite flat side surfaces along the lateral edges thereof. The ears may be frustoconical or hemispherical or the like and are slidingly received in elongated slots which can be straight or arcuate. The main body portions of the occluders have rectilinear surfaces that are aligned parallel to the centerline through the valve in the open position, so as to give low resistance to blood flow. However, when the backflow of blood displaces the occluders upstream, the slot arrangements are such that even though the occluder bodies are parallel, pivoting towards the closed position orientation begins essentially immediately, and the closing movement is of short duration so as to minimize regurgitation.
