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

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.

10. In combination,
a heart valve having an orifice ring providing a blood flow duct and having an annular groove about the outer circumferential surface of said orifice ring; - and
a suture ring comprising; a stiffening ring, having first and second axial ends, mounted in surrounding relationship about said valve body at said annular groove of said valve body, said stiffening ring including a tapered outer surface section; a resilient ring positioned about the outer circumferential surface of said valve body proximate said first end of said stiffening ring; a fabric tube, having a mesh weave and first and second axial ends, covering said stiffening ring and said resilient ring, and interposed between said resilient ring and said stiffening ring; a first fastener band frictionally engaging said fabric tube between said first fastener band and said outer circumferential surface of said valve body proximate to said first end of said stiffening ring; a second fastener band frictionally engaging said fabric tube between said outer circumferential surface of said valve body proximate to said second end of said stiffening ring; first attachment means for attaching said first end of said fabric tube to a first location along said tube; and second attachment means for attaching said second end of said tube to a second location along said tube. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
