Abstract
A suture ring assembly for a prosthetic heart valve is provided which includes a suture ring body, suture ring flange, and an interior engagement surface that are formed as a unitary structure composed of pyrocarbon material or the like. The suture ring flange extends radially outward from said suture ring body and may be of an arcuate or straight design. Moreover, the suture ring flange has a plurality of pre-fabricated holes extending axially therethrough and is particularly designed for securing the assembly to the residual heart tissue. The suture ring interior engagement surface is proportioned to surround the exterior surface of the valve body such that it can rotate relative to the heart valve body. The suture ring assembly and the valve body are specifically designed to axially engage each other so as to prevent disengagement in either axial direction. Any axial displacements that may occur during the opening and closing of the prosthetic heart valve are absorbed or dampened with spring-like, shock-absorbing mechanisms formed as part of a retaining ring which is part of the suture ring assembly.
