Connection Systems for Two Piece Prosthetic Heart Valve Assemblies and Methods for 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 implantable within the biological annulus;
a sewing cuff extending outwardly from the annular member;
a plurality of guide rails comprising first ends coupled to one of the annular member and the sewing cuff for guiding a prosthetic valve towards at least one of the sewing cuff and the annular member; and
one or more locking tabs positioned on the guide rails for securing a prosthetic valve relative to the prosthesis.

Abstract
A heart valve assembly includes a prosthesis for receiving a prosthetic valve to replace a preexisting natural or prosthetic heart valve within a biological annulus adjacent a sinus cavity. The prosthesis includes an annular member, a sewing cuff extending radially outwardly from the annular member and a plurality of guide rails extending from the prosthesis. The prosthetic valve includes an annular member, at least one valve and receptacles for receiving the guide rails. Locking tabs positioned on the guide rails engage with locking windows in the receptacles to attach the prosthetic valve with the prosthetic valve.
