CA 1112804

Abstract of the Disclosure A prosthetic valve, suitable for use as a mitral valve replacement, has a D-shaped annular seat-forming member and obturating flap, the flap hav- ing a major area formed by a rigid sheet of similar D-shape and extent for direct support on the seat when the valve is closed, and a flexible sheet hinge connecting the flap and annular member as a hinge along their straight edge portions. The rigid sheet is preferably scalloped around its free edge, with a flexible skirt being located across the incursions of this shaping, and is also preferably dished inwardly towards the annular member. The valve of the present invention avoids the major thombogenic complications inherent in the known ball and cage valves.
