Abstract

A prosthetic heart valve holder system includes a prosthetic heart valve having a base at an inflow end, a plurality of commissure posts extending from the base toward an outflow end, and valve leaflets secured to the commissure posts to permit flow through the heart valve. A deflector is provided at the outflow end having a central hub and a plurality of arms extending from the central hub secured to and covering the tips of respective commissure posts. A valve support body is secured to the base and a post connects the valve support body to the hub of the deflector. The plurality of arms are sufficiently collapsible such that, in a first position, free ends of the arms are located axially between the hub and the valve support body to prevent suture looping during an implant procedure, and in a second position, the hub is located axially between the free ends of the arms and the valve support body to permit removal of the deflector from the outflow side of the valve, through the valve leaflets, to the inflow side of the valve.

First claim

What is claimed is:

1. A prosthetic heart valve holder comprising:
a deflector having a hub and a plurality of arms extending radially outwardly from the hub, each of the arms having a first end connected to the hub and a free second end positioned radially outwardly from the hub;
a valve support body; and
a post extending between and connecting the valve support body and the hub, wherein an outer width of the hub is greater than an outer width of the post;
wherein the arms are deflectable axially relative to the hub, such that in a first configuration the second ends of the arms are positioned closer axially to the valve support body than the hub is to the valve support body, and in a second configuration the second ends of the arms are positioned farther away axially from the valve support body than the hub is to the valve support body.

2. The prosthetic heart valve holder of claim 1 , wherein the deflector comprises at least three arms.

3. The prosthetic heart valve holder of claim 1 , wherein an end of the post is insertable into the hub of the deflector.

4. The prosthetic heart valve holder of claim 1 , wherein the post comprises a solid pin.

5. The prosthetic heart valve holder of claim 1 , wherein the post is molded or press-fit to the hub of the deflector.

6. The prosthetic heart valve holder of claim 1 , wherein an axial distance between the hub of the deflector and the valve support body remains fixed.

7. The prosthetic heart valve holder of claim 1 , further comprising an adaptor that is detachably connectable to a side of the valve support body opposite the post and the deflector, wherein the adaptor comprises a suture shield for covering sutures which connect a prosthetic heart valve to the prosthetic heart valve holder.

8. The prosthetic heart valve holder of claim 1 , further comprising a handle that is detachably connectable to a side of the valve support body opposite the post.

9. A prosthetic heart valve holder comprising:
a deflector having a hub and a plurality of arms extending radially outwardly from the hub, each of the arms having a first end connected to the hub and a free second end positioned radially outwardly from the hub;
a valve support body; and
a post extending between and connecting the valve support body and the hub, wherein each of the arms remains entirely spaced apart from the post;
wherein the arms are deflectable axially relative to the hub, such that in a first configuration the second ends of the arms are positioned closer axially to the valve support body than the hub is to the valve support body, and in a second configuration the second ends of the arms are positioned farther away axially from the valve support body than the hub is to the valve support body.

10. The prosthetic heart valve holder of claim 9 , wherein the deflector comprises at least three arms.

11. The prosthetic heart valve holder of claim 9 , wherein the hub is positioned between the post and each of the arms and prevents the arms from contacting the post.

12. The prosthetic heart valve holder of claim 9 , wherein each of the arms defines a transversely extending notch that forms a living hinge.

13. The prosthetic heart valve holder of claim 9 , wherein the post comprises a solid pin.

14. The prosthetic heart valve holder of claim 9 , wherein the post is molded or press-fit to the hub of the deflector.

15. The prosthetic heart valve holder of claim 9 , wherein an axial distance between the hub of the deflector and the valve support body remains fixed.

16. The prosthetic heart valve holder of claim 9 , further comprising an adaptor that is detachably connectable to a side of the valve support body opposite the post and the deflector, wherein the adaptor comprises a suture shield for covering sutures which connect a prosthetic heart valve to the prosthetic heart valve holder.

17. The prosthetic heart valve holder of claim 9 , further comprising a handle that is detachably connectable to a side of the valve support body opposite the post.

18. A prosthetic heart valve holder comprising:
a deflector having a hub and a plurality of arms extending radially outwardly from the hub, each of the arms having a first end connected to the hub and a free second end positioned radially outwardly from the hub;
a valve support body; and
a post extending between and connecting the valve support body and the hub;
wherein the arms are deformable axially relative to the hub, such that in a first configuration the second ends of the arms are positioned closer axially to the valve support body than the hub is to the valve support body, and in a second configuration the second ends of the arms are positioned farther away axially from the valve support body than the hub is to the valve support body.

19. The prosthetic heart valve holder of claim 18 , wherein the arms of the deflector comprise a material with a durometer in the range of shore A30 to shore A70.

20. The prosthetic heart valve holder of claim 18 , wherein each of the arms defines a transversely extending notch that forms a living hinge.
