Abstract:
1. A prosthetic heart valve for implant at a valve annulus, comprising: a non-planar support frame defining a non-circular orifice about an axis along an inflow-outflow direction, the orifice having a longer dimension along a major axis and a shorter dimension along a perpendicular minor axis, the support frame having an inflow edge and commissures extending generally axially therefrom in the outflow direction to an axial height of at least 6 mm; and four separate flexible leaflets arranged in two pairs of diametrically opposed, symmetric leaflets, wherein a first pair of leaflets is substantially smaller than a second pair of leaflets each being separately mounted for movement on the support frame and being supported between the axially extending commissures to provide a one-way valve in the non-circular orifice.
