Patent ID: 7776084

Claim:
A prosthetic mitral heart valve for implant at a mitral valve annulus, the annulus featuring two anterior trigones spaced apart approximately 120°, comprising: a support frame defining an orifice about an axis along an inflow-outflow direction; a plurality of leaflets mounted for movement on the support frame to provide a one-way valve in the orifice; and a sewing ring connected to and positioned around the support frame for attaching the heart valve to the mitral valve annulus, the sewing ring having an inflow end and an outflow end, wherein the outflow end includes exactly two axially-raised portions relative to the remainder of the outflow end that are spaced apart so as to register with the two anterior trigones upon implantation, the two axially-raised portions both extending the full radial extent of the sewing ring, wherein the support frame has an undulating shape including three axially-oriented commissures extending toward the outflow direction alternating with three cusps extending toward the inflow direction, two of the commissures being located adjacent the two axially-raised portions of the sewing ring, and the heart valve includes three flexible leaflets mounted around the undulating shape of the support frame.
