Abstract

A suture ring is provided for supporting a heart valve prosthesis having a valve body with an outer circumferential surface and an annular groove formed in the surface, and includes: a stiffening ring, having first and second ends, mounted in surrounding relationship about the valve body at the annular groove of the valve body, the stiffening ring including a tapered outer surface section; a resilient ring positioned about the outer circumferential surface of the body proximate the first end of the stiffening ring; a fabric tube, having a mesh weave body and first and second ends, covering the stiffening ring and the resilient ring, and interposed between the resilient ring and the stiffening ring; a first fastener band frictionally engaging the fabric tube between the first fastener band and the outer circumferential surface of the valve body proximate to the first end of the stiffening ring; a second fastener band frictionally engaging the fabric tube between the outer circumferential surface of the valve body proximate to the second end of the stiffening ring; first attachment means for attaching the first end of the fabric tube to a first location along the mesh weave body; and second attachment means for attaching the second end of the fabric tube to a second location along the mesh weave body.
