Abstract
Abstract A holder for engaging a heart valve prosthesis during implantation includes a mechanism for attaching the holder to the heart valve prosthesis. The heart valve prosthesis includes a circular valve body having an annulus with a substantially annular aperture therein. At least one movable occluder is carried in the aperture and is movable between an open position and a closed position. The attachment mechanism attaches to the occluder thereby securing the holder to the heart valve prosthesis.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
228 words
An apparatus for holding a heart valve prosthesis and providing a low profile during implantation, the heart valve prosthesis including a heart valve prosthesis body and a movable occluder having a first occluder surface and a second occluder surface opposite the first occluder surface, the apparatus comprising: a top member sized to fit proximate an annulus of the heart valve prosthesis; a lip portion coupled to the top member adapted for abutting the annulus of the heart valve prosthesis; an interior extension coupled to the top member extending through heart valve prosthesis body and generally conforming to an interior portion of the prosthesis body; a distal extension coupled to the interior extension extending beyond the heart valve prosthesis body opposite the top member to protect the movable occluder; a conforming surface in the top member shaped to conform to the first occluder surface to maintain the first occluder surface in a substantially closed position when the top member and lip portion engage the prosthesis body; and a suture extending around the top member and adapted to extend around the movable occluder, thereby coupling the top member to the heart valve prosthesis body and the conforming surface to the fist occluder surface and maintaining the movable occluder in the substantially closed position whereby the occluder is protected from damage by the heart valve prosthesis body and the distal extension.
Claim 2
Independent Claim
228 words
An apparatus for holding a heart valve prosthesis and providing a low profile during implantation, the heart valve prosthesis including a heart valve prosthesis body and a movable occluder having a first occluder surface and a second occluder surface opposite the first occluder surface, the apparatus comprising: a top member sized to fit proximate an annulus of the heart valve prosthesis; a lip portion coupled to the top member adapted for abutting the annulus of the heart valve prosthesis; an interior extension coupled to the top member extending through heart valve prosthesis body and generally conforming to an interior portion of the prosthesis body; a distal extension coupled to the interior extension extending beyond the heart valve prosthesis body opposite the top member to protect the movable occluder; a conforming surface in the top member shaped to conform to the first occluder surface to maintain the first occluder surface in a substantially closed position when the top member and lip portion engage the prosthesis body; and a suture extending around the top member and adapted to extend around the movable occluder, thereby coupling the top member to the heart valve prosthesis body and the conforming surface to the fist occluder surface and maintaining the movable occluder in the substantially closed position whereby the occluder is protected from damage by the heart valve prosthesis body and the distal extension.
Claim 3
Dependent Claim
38 words
The apparatus of claim 1 including a second conforming surface adapted to conform to a first surface of a second movable occluder of the heart valve prosthesis to maintain the second movable occluder in a substantially closed position.
Claim 4
Dependent Claim
19 words
The apparatus of claim 1 wherein the top member includes a suture hole formed therein for receiving the suture.
