Abstract

An annuloplasty system including an annuloplasty prosthesis and a holder for the prosthesis. At least one rigid, downwardly extending penetrating member extends into the prosthesis. Preferably, at least one outwardly extending member extends alongside a lower surface of the prosthesis, preventing the prosthesis from moving downward and off of the penetrating member.

Claims

1. An annuloplasty system, comprising:

a first holder component having an upper surface, a lower surface and a circumferential surface corresponding generally to the configuration of a heart valve annulus;

an annuloplasty prosthesis, located adjacent to and extending at least partially around the circumferential surface; and

at least one rigid downwardly extending penetrating member mounted to the holder and extending through the prosthesis and holding it adjacent the circumferential surface.

2. A system as in claim 1, wherein the prosthesis is a flexible annuloplasty prosthesis.

3. A system as in claim 1, wherein the circumferential surface comprises a groove in which at least a portion of the prosthesis is located.

10. A system as in claim 1, wherein the holder comprises a second holder component, coupled to and extending above the first holder component.

11. A system as in claim 10, wherein the at least one penetrating member is mounted to the second holder component.

12. A system as in claim 11, wherein the second holder component is movable upwardly relative to the first holder component to withdraw the penetrating member from the prosthesis.

13. A system as in claim 12, wherein the second holder component is releasably secured adjacent to the first holder component, temporarily preventing upward movement of the second holder component.

14. A system as in claim 12, wherein the second holder component is releasably secured to the first holder component by a cuttable suture.

15. A system as in claim 12, wherein the second holder component is completely removable from the first holder component.

16. A system as in claim 12, comprising means for retaining the second holder component to the first holder component after upward movement of the second holder component.

17. A system as in claim 12, wherein the first holder component is deformable to display a reduced circumference.

18. A system as in claim 17, wherein the second holder comprises means for preventing deformation of the first holder component until upward movement of the second holder component.

19. A system as in claim 10, wherein the at least one penetrating member is mounted to the first holder component.

4. An annuloplasty system, comprising:

a first holder component having an upper surface, a lower surface and a circumferential surface corresponding generally to the configuration of a heart valve annulus;

an annuloplasty prosthesis, located adjacent to and extending at least partially around the circumferential surface; and

at least one rigid downwardly extending penetrating member mounted to the holder and extending into the prosthesis and holding it adjacent the circumferential surface

wherein the circumferential surface comprises at least one outwardly extending member extending alongside a lower surface of the prosthesis and preventing the prosthesis from moving downward and off of the penetrating member.

5. A system as in claim 4 wherein the outwardly extending member is located below the downwardly extending member.

6. A system as in claim 4 wherein the at least one downwardly extending member comprises a plurality of downwardly extending members and wherein the at least one outwardly extending member comprises a plurality of outwardly extending members, located below respective ones of the penetrating members.

7. A system as in claim 4 wherein the penetrating member extends into the outwardly extending member, preventing the prosthesis from moving downward and off of the penetrating member.

8. A system as in claim 4 wherein the at least one downwardly extending member comprises a plurality of penetrating members and wherein the at least one outwardly extending member comprises a plurality of outwardly extending members, into which respective ones of the penetrating members extend.

9. A system as in claim 4 wherein the at least one downwardly extending member comprises a plurality of penetrating members and wherein the at least one outwardly extending member extends around a portion the circumferential surface and is located below a plurality of the penetrating members.
