ABSTRACT:
A mechanical artificial heart valve is provided and consists of an annular shaped orifice, to which a single (or multiple) bicurved leaflet(s) is (are) hinged. The curves are planar and are generated from two intersecting circular arcs. The valve is constructed to cause a predominately accelerating flow through the orifice. This significantly reduces the flow separation from the leaflets. In addition, the leaflets are shaped so as to reduce the closing reflux volume through the orifice during the regurgitation phase of flow. These improvements tend to significantly decrease the work load on the heart.
