Abstract

A holder for prosthetic heart valves including an annular base and prosthetic valve leaflets extending between commissure regions oriented axially with respect to the base. The holder includes a grip element from which a plurality of arms extend for supporting the prosthetic heart valve in an intermediate position between the commissures. Protecting formations extend radially with respect to the grip element to protect the commissure regions. The grip element includes a first rotational element for coupling to a handle and at least one second coupling element for coupling the grip element of the holder to a support element thereby impeding its rotation.

Claims

1. A holder for a prosthetic heart valve, the valve including an annular base and a plurality of leaflets extending between commissure regions, the holder comprising a grip element, a plurality of arms extending from the grip element and configured for supporting the prosthetic heart valve in an intermediate position between the commissure regions, and a plurality of commissure formations extending from the grip element, the formations configured to extend radially from the grip element to cover an outward most point of the commissure regions.

2. The holder of claim 1, further comprising a support formation coupled to distal ends of the arms, the annular formation configured to support the base.

3. The holder of claim 2, wherein the support formation is substantially continuous.

4. The holder of claim 1, wherein the commissure formations are made of a transparent or a translucent material.

5. The holder of claim 1, wherein the commissure formations have a shape configuration selected from the group consisting of:

a V-shape, a finger-nail-shape, and a petal-shape.

6. The holder of claim 4, wherein the plurality of commissure formations jointly form a substantially-triangular structure.

7. The holder of claim 1, further including openings to pass suture threads therethrough to fasten the valve onto the holder.

8. The holder of claim 7, wherein the openings are provided in correspondence with the arms.

9. The holder of claim 7, wherein the openings are provided in correspondence with the commissure formations.

10. The holder of claim 7, wherein the openings are provided both in correspondence with the arms and in correspondence with the commissure formations.

11. The holder of claim 1, wherein the commissure formations include projecting ridges on a proximal face.

12. The holder of claim 1, wherein the grip element includes:

at least one first rotational element for coupling the grip element to a handle, and

at least one second element for coupling the grip element to a support element configured to impede rotation of the grip element.

13. The holder of claim 12, wherein the at least one first coupling element is a screw-thread coupling element.

14. The holder of claim 13, wherein the screw-thread coupling element is a threaded rod.

15. The holder of claim 12, wherein the at least one second coupling element includes at least one lateral notch on the grip element.

16. The holder of claim 1, wherein the arms extend downwardly from the grip element a sufficient distance to effect a gap between the valve commissures and the commissure formations, upon attachment of the holder to the valve.

17. A holder for a prosthetic heart valve, the valve including an annular base and a plurality of leaflets adapted to mate at coapting edges, the holder comprising a grip element and a plurality of formations extending radially from the grip element, wherein the formations are configured to protect the coapting edges.

18. The holder of claim 17 wherein the formations are further configured to avoid contacting the coapting edges, while the prosthetic heart valve is secured to the holder.
