Abstract
A heart valve including a generally annular body and a disc within the body pivotable about a centerline of the disc. Vanes project from one face of the disc in a direction opposite the flow direction through the valve, fluid flow against the vanes causing the valve to open. A baffle extends across the body adjacent the face of the disc opposite the face from which the vanes project, the baffle directing fluid flowing in the no-flow direction of the valve against the disc so as to close the valve. The disc portions on opposite sides of the pivot axis are of substantially equal size and weight. The disc is limited to pivoting through an acute angle, and in certain embodiments may also rotate in its own plane. The vanes may be arranged on only one half the disc, or symmetrically on the entire disc, and the vanes are preferably spaced apart to define openings between them to accommodate fluid flow. A second baffle may extend across the body adjacent the face of the disc from which the vanes project.
