Connection systems for two piece prosthetic heart valve assemblies and methods for making and using them
First Claim
1. A prosthesis for receiving a prosthetic valve to replace a preexisting natural or prosthetic heart valve within a biological annulus, comprising:
- an annular member sized to be received within a biological annulus;
a sewing cuff extending outwardly from the annular member above a plane of the annular member;
a rail ring disposed adjacent the annular member within a fabric covering covering the annular member and the rail ring;
a plurality of guide rails extending from the rail ring transversely relative to a plane defined by the rail ring, the guide rails extending from the rail ring through respective openings in the fabric covering; and
a collar attached along its length to an outer surface of the fabric covering along an inner surface of the sewing cuff above the plane defined by the rail ring.

Abstract
A heart valve assembly includes a prosthesis and a prosthetic valve to replace a preexisting natural or prosthetic heart valve within a biological annulus. The prosthesis includes an annular member, a flexible core at least partially defining a sewing cuff extending radially outwardly from the annular member, a rail ring disposed between the flexible core and the annular member, and a plurality of guide rails extending from the rail ring through respective openings in the flexible core. A fabric covering covers the prosthesis, and the guide rails extend through respective openings in the fabric covering. The prosthetic valve includes a frame including receptacles for receiving respective guide rails. After implanting the prosthesis within a biological annulus, the prosthetic valve is advanced along the guide rails until retention elements on the guide rails engage the receptacles to secure the prosthetic valve relative to the prosthesis.
