Abstract

A holder 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 suture cuff thereby affixing the device to the heart valve prosthesis. The attachment mechanism may be actuated to disengage the heart valve prosthesis.

Claims

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

a body adapted for abutting the heart valve prosthesis;

a bendably rigid tip member having a proximal end and a free distal end coupled to the body and adapted to detachably engage the suture cuff by extending into the suture cuff, whereby the free distal end may be selectively detached from the suture cuff by movement of the proximal end; and

an elongated handle having a distal end coupled to the body.

2. The apparatus of claim 1 wherein the prosthesis has an annulus and the handle is adapted to extend in a direction generally parallel with a plane defined by the annulus when the heart valve is positioned adjacent the body.

3. The apparatus of claim 1 wherein the tip member comprises a bendable coil which is adapted to be removably coiled into the suture cuff to secure the heart valve to the apparatus.

4. The apparatus of claim 1 wherein the tip member further comprises a second free distal end coupled to the body and adapted to detachably engage the suture cuff.

5. The apparatus of claim 4 wherein the free distal ends of the tip member are adapted to engage the suture cuff at approximately opposite sides of the suture cuff forming a pivot therebetween.

6. The apparatus of claim 5 wherein the tip member further comprises a third free distal end adapted to engage the suture cuff at a location between the first and second distal ends.

7. The apparatus of claim 6 wherein the third distal end is adapted for movement along an axis of the elongated handle thereby translating a force along the axis adapted to cause the prosthesis to rotate about the pivot.

8. The apparatus of claim 1 wherein the suture cuff forms an annulus and the distal end of the tip member is adapted to extend in an angular direction into the suture cuff when the heart valve is coupled to the apparatus.

9. The apparatus of claim 8 including a plurality of free distal ends which can extend at an angular direction into the suture cuff and be selectively removable from the cuff by movement in a reverse angular direction.

10. The apparatus of claim 1 wherein the suture cuff is annular and the free distal end of the tip member can extend in a radially outward direction into the suture cuff.

11. The apparatus of claim 10 including a plurality of free distal ends which can extend in radially outward directions into the suture cuff, the plurality of free distal ends being selectively removable from the suture cuff by movement in a radially inward direction.

12. The apparatus of claim 11 including an actuating mechanism coupled to the plurality of free distal ends providing the radially inward movement to selectively remove the distal ends of the tip member.

13. The apparatus of claim 12 wherein the actuating mechanism includes a spring.
