Abstract

An implantation device for a prosthetic heart valve includes a valve holder for maintaining the prosthetic heart valve in a closed configuration and at least one protective sheet coupled to the valve holder, the at least one protective sheet being configured to cover a leaflet of the heart valve during implantation.

Claims

1. An implantation device for a prosthetic heart valve, comprising:

a valve holder for maintaining the prosthetic heart valve in a closed configuration; and

at least one protective sheet coupled to the valve holder, the at least one protective sheet being configured to cover a leaflet of the heart valve during implantation.

2. The implantation device of claim 1, wherein the at least one protective sheet includes three protective sheets.

3. The implantation device of claim 1, wherein the at least one protective sheet includes a protective sheet for each leaflet of the prosthetic heart valve.

4. The implantation device of claim 1, wherein the at least one protective sheet is comprised of at least one of Ultem, Delrin, Udel, and PEEK.

5. The implantation device of claim 1, wherein the valve holder includes suture features for coupling the at least one protective sheet to the heart valve.

6. The implantation device of claim 1, wherein each protective sheet includes a leg coupleable to a ring of a heart valve at a suture feature.

7. The implantation device of claim 1, wherein the valve holder includes a slot for receiving a handle.

9. The implantation device of claim 1, wherein the prosthetic heart valve is a mitral valve.

10. The implantation device of claim 1, wherein the at least one protective sheet includes three protective sheets.

11. The implantation device of claim 1, wherein the at least one protective sheet includes a protective sheet for each leaflet of the prosthetic heart valve.

12. The implantation device of claim 1, wherein the at least one protective sheet is comprised of at least one of Ultra-high-molecular-weight polyethylene (UHMWPE), PTFE, polyurethane.

13. The implantation device of claim 1, wherein the valve holder includes suture features for coupling the at least one protective sheet to the heart valve.

14. The implantation device of claim 1, wherein each protective sheet includes a leg coupleable to a ring of a heart valve at a suture feature on the leg.

15. The implantation device of claim 1, wherein the valve holder includes a slot for receiving a handle.

16. The implantation device of claim 1, wherein the at least one protective sheet is configured to wrap around the prosthetic heart valve.

17. The implantation device of claim 1, wherein the valve holder includes suture features for coupling the at least one protective sheet to the valve holder.

18. The implantation device of claim 1, further comprising a sheet clamp coupled to the valve holder for clamping a portion of the at least one sheet protector.

19. The implantation device of claim 18, wherein the sheet clamp includes complementary upper and lower portions configured to retain a protective sheet between the upper and lower portions.

20. The implantation device of claim 19, wherein the upper and lower portions include complementary suture holes for coupling the upper portion to the lower portion via sutures.

8. An implantation device for a prosthetic heart valve comprising:

a valve holder for maintaining the prosthetic heart valve in a closed configuration;

a chimney coupled to the valve holder, the chimney defining a lumen; and

at least one protective sheet coupled to the valve holder, and extending through the lumen of the chimney.
