Abstract

An annuloplasty ring and support assembly includes a ring support that has a peripheral wall with a peripheral shoulder surface, and a flange extending at generally right angles to the shoulder surface. The flange is removed or terminated in a selected portion of the peripheral wall so that the shoulder surface is unobstructed and provides a backing support against which a cutting force will be reacted when the annuloplasty ring is cut.

Claims

1. An annuloplasty ring holder comprising a body having a peripheral wall including a peripheral surface for supporting an annuloplasty ring, and a flange extending from the peripheral wall along a substantial portion of the peripheral wall, and said flange terminating along at least one selected length of the peripheral wall to provide access to use the surface of the peripheral wall as a backing for forces moving against the surface.

2. The ring holder of claim 1, wherein the peripheral wall surface faces outwardly.

3. The ring holder of claim 2, wherein the flange extends outwardly from the peripheral wall along one edge of the peripheral wall surface.

4. The ring holder of claim 1, wherein the ring holder has a plurality of openings defined therein for sutures.

5. The ring holder of claim 4 including openings for sutures in the region of the length of the peripheral wall where the flange terminates.

6. The ring holder of claim 1, wherein the peripheral wall encircles an open center.

7. The ring holder of claim 6 and a reinforcing bar extending across the open center and being integral with the peripheral wall.

8. The ring holder of claim 6 and a handle connector supported within a space bounded by the peripheral wall.

9. The ring holder of claim 4, wherein the holder has a plurality of cutting grooves formed thereon and positioned between openings provided for suturing.

10. The ring holder of claim 9, wherein the cutting grooves are formed in a top surface of the holder and at least one cutting groove extending across the flange.

11. The ring holder of claim 1, wherein said surface is substantially perpendicular to a plane of the holder.

12. The ring holder of claim 7, wherein the flange is generally parallel to the plane of the holder and is flush with an upper surface of the peripheral wall.

15. The ring holder of claim 1 and a plurality of suture retainers formed on the holder, including grooves on top and bottom surfaces of the peripheral wall to define posts around which sutures may be looped.

13. An annuloplasty ring holder comprising a body having a peripheral wall including a peripheral surface for supporting an annuloplasty ring and a flange extending from the peripheral wall along a substantial portion of the peripheral wall, said flange terminating at two annularly spaced locations along the peripheral wall to provide access to use the surface of the peripheral wall as a backing for forces moving against the surface, wherein there is a tab comprising a flange section positioned between the two annularly spaced locations.

14. The ring holder of claim 13, wherein there are plurality of suture retainers on the peripheral wall, and including suture retainers aligned with said tab.

16. An annuloplasty ring assembly comprising a substantially flexible annuloplasty ring, a body defining a peripheral wall against which an annuloplasty ring is positioned and retained, said peripheral wall having a shoulder surface against which the annuloplasty ring rests, and a flange on the peripheral wall positioned at generally right angles to the shoulder surface to support the annuloplasty ring, said flange terminating at spaced locations along a selected length of the peripheral wall so that said shoulder surface is unobstructed and forms a reaction wall for cutting the annuloplasty ring at locations where the shoulder surface is unobstructed.

17. The annuloplasty ring assembly of claim 16 including a plurality of openings defined in the holder for retaining sutures to hold the annuloplasty ring against the shoulder and the flange.

18. The annuloplasty ring assembly of claim 16, wherein a side of said body has a plurality of slots extending thereacross, and wherein sutures retaining the annuloplasty ring pass across the slots.

19. An annuloplasty ring holder for supporting an annuloplasty ring, the holder including a body defining a peripheral wall against which an annuloplasty ring is positionable, suture retaining openings formed on the peripheral wall, said peripheral wall having a peripheral shoulder surface and a flange extending at generally right angles to the shoulder surface to support an annuloplasty ring, said flange terminating at spaced locations along a selected length of the peripheral wall so that said shoulder surface is unobstructed and forms a surface for supporting an annuloplasty ring on the holder under cutting forces toward the shoulder surface at locations where the shoulder surface is unobstructed.

20. The annuloplasty ring holder of claim 19 including a plurality of suture retainer openings on the body for retaining sutures to hold an annuloplasty ring against the shoulder and the flange.

21. The annuloplasty ring holder of claim 19, wherein a side of said body has a plurality of slots extending thereacross, and wherein sutures retaining an annuloplasty ring on the body pass across the slots.

22. The annuloplasty ring holder of claim 19, wherein there is a flange portion forming a tab between the spaced locations.

23. The annuloplasty ring of claim 19, wherein the peripheral wall has spaced first and second sides between which the shoulder surface extends, and a plurality of suture retainers on each of the first and second sides to retain sutures for an annuloplasty ring relative to both of said sides.

24. The annuloplasty ring holder of claim 23, wherein the suture retainer comprises posts for retaining a suture loop.

25. The annuloplasty ring of claim 24, wherein the peripheral wall has grooves formed therein to define the posts.

26. The annuloplasty ring of claim 23 wherein the suture retained by the suture retainers on first and second sides passes alternately between the first and second sides through an annuloplasty ring, to thereby resist axial and lateral forces on such annuloplasty ring.
