Abstract
A heart valve has an elliptical occluder mounted for pivoting in an annular heart valve body with a circular passageway between an open position to allow blood flow through the passageway and a closed position to block blood flow. A pair of ears extend from the occluder into a pair of opposed pie-shaped depressions in the interior wall of the valve body so that the relative rotation of the ears along the verticies of the depressions defines an eccentric pivot axis. The occluder seats in its closed position against a lip which protrudes inward of the interior wall on the major side of the eccentric axis.
