Abstract

A tissue valve holder for holding a tissue heart valve bioprosthesis such that the tissue valve may be supported without contacting any surface, regardless of whether or not the valve is in a container. The tissue valve holder includes a holder assembly adapted to be secured to the tissue valve. The holder assembly may include a holder body and a removable disk. The holder assembly and the tissue valve secured thereto rest on a support structure. The support structure may comprise a support surface and a plurality of support legs. The support surface, in turn, may comprise an annular ring with the support legs connected thereto. The holder assembly rests on the support surface with the tissue valve suspended in the center of the ring.

Claims

1. A holder and heart valve assembly, comprising:

a tissue heart valve prosthesis which includes commissure posts;

a holder assembly having a plurality of arms adapted to fit with the commissure posts;

a suture coupling at least one of the arms to the commissure post to secure the commissure post to the arm;

a support structure comprising a ring which extends around the prosthesis proximate the commissure posts and the arms of the holder assembly, the support structure having a plurality of support legs and a support surface formed in the ring, the legs extending from the ring, wherein the holder assembly fits with the support structure such that the tissue heart valve prosthesis is suspended from the holder assembly without contacting any other surface.

2. The holder and heart valve assembly of claim 1 including a removable disk adapted to couple to the holder assembly, wherein the removable disk rests on the support surface of the support structure.

3. The holder and heart valve assembly of claim 2 wherein the removable disk includes a slot formed therein adapted to engage the holder assembly.

4. The holder and heart valve assembly of claim 1 wherein the support structure includes two side openings formed therein.

5. The holder and heart valve assembly of claim 1 wherein the holder assembly includes suture holes and the holder assembly is sutured to the tissue heart valve prosthesis.

6. The holder and heart valve assembly of claim 5 wherein the holder assembly includes a scalpel guide having a notch formed therein adapted to guide a scalpel when cutting the suture.

7. The holder and heart valve assembly of claim 1 wherein the holder assembly is adapted to fit in a container and includes a keyed slot formed therein adapted to receive a tip of a handle having key tabs formed therein.

8. The holder and heart valve assembly of claim 1 wherein the holder assembly is adapted for coupling to a tissue heart valve prosthesis in either a mitral or aortic configuration.

9. The holder and heart valve assembly of claim 1 including a holder support adapted to couple to the holder assembly and wherein the holder support couples to the support structure.

10. The holder and heart valve assembly of A holder for holding a tissue heart valve prosthesis as in claim 9 wherein the holder support includes a threaded screw which is received in a threaded opening in the holder assembly.

11. A holder for holding a tissue heart valve prosthesis as in claim 9 wherein the holder support includes protruding legs adapted to abut an outer perimeter of the valve prosthesis.
