Abstract

A device for engaging a heart valve prosthesis during implantation includes a mechanism for attaching the device 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 includes a member which couples to the circular valve body thereby affixing the device to the heart valve prosthesis. The thickness of the device which extends in a direction above the heart valve prosthesis is reduced. The device is selectively removable from the heart valve prosthesis following implantation of the prosthesis in the heart tissue annulus of a patient.

Claims

1. An apparatus for holding a heart valve prosthesis during implantation, the heart valve prosthesis including a heart valve prosthesis body and a movable occluder, the apparatus comprising:

a low profile holder body having an engaging side including a lip portion for abutting the heart valve prosthesis body and a top substantially flat side opposite the engaging side, the holder body sized to extend above the heart valve prosthesis body a distance which is less than a thickness of the heart valve prosthesis body; and

first and second jaws movably coupled to the holder body having a distal portion carrying a distal tip, the distal portion sized to extend through an annulus of the heart valve prosthesis body whereby the distal tip engages the prosthesis body on a distal side of the prosthesis body opposite the lip portion, thereby securing the heart valve prosthesis body between the lip portion and the distal tip;

wherein the first and second jaws are movable between an engaged position which couples the holder body to the heart valve prosthesis body and a disengaged position in which the body is freed from the heart valve prosthesis body, and a top side of the first and second jaws opposite the distal portion is substantially flush with the top side of the holder body when the first and second jaws are in the engaged position.

2. The apparatus of claim 1 wherein the distal portions of the first and second jaws are sized to extend beyond an edge of the distal side of the prosthesis body, thereby protecting the moveable occluder during implantation.

3. The apparatus of claim 1 wherein the heart valve prosthesis includes two moveable occluders and the moveable jaws fit between the two occluders.

4. The apparatus of claim 1 wherein the jaws are pivotally coupled to the holder body.

5. The apparatus of claim 1 wherein the holder body includes a first suture hole and the first jaw includes a second suture hole, the first and second suture holes substantially aligned when the jaw is in the engaged position to receive a suture therethrough to secure the jaw in the engaged position.
