FOLDABLE PROSTHESES, MULTIPLE COMPONENT PROSTHETIC HEART VALVE ASSEMBLIES, AND APPARATUS AND METHODS FOR DELIVERING THEM
First Claim
1. A heart valve assembly implantable within a biological annulus, comprising:
- a first prosthesis comprising an annular member implantable within the biological annulus, the annular member being compressible radially inwardly from a relaxed condition to a contracted condition to facilitate delivery into a biological annulus, the annular member being resiliently expandable towards the relaxed condition;
a second valve prosthesis comprising an annular frame and at least one valve element; and
one or more connectors for securing the second prosthesis to the first prosthesis.

Abstract
Multiple component heart valves and apparatus and methods for implanting them are provided. The heart valve generally includes a first annular prosthesis and a second valve prosthesis. The first prosthesis includes an annular member compressible from a relaxed condition to a contracted condition to facilitate delivery into a biological annulus, the annular member being resiliently expandable towards the relaxed condition. The first prosthesis also includes guide rails extending therefrom. The second prosthesis includes an annular frame, valve elements, and receptacles for receiving respective guide rails therethrough when the second prosthesis is directed towards the first prosthesis. In addition, a valve holder may releasably carry the valve prosthesis that includes channels for receiving respective guide rails therethrough when the guide rails are received through the valve prosthesis. A delivery tool is also provided that includes an actuator for selectively compressing the annular member into the contracted condition.

20. A system for implanting a prosthesis into a biological annulus, comprising:
-
a first prosthesis comprising an annular member implantable within the biological annulus, and a sewing cuff extending outwardly from the annular member; and
a delivery tool comprising an elongate shaft including a proximal end with a handle, a distal end including a plurality of supports and a plurality of movable arms, and an actuator for moving the arms towards and away from the supports for securing and releasing the first prosthesis between the supports and the arms, the first prosthesis being folded into a contracted condition when secured between the supports and the arms.
