The holder is also provided with one or more suture snuggers for tensioning the drawstring.

Claims

1. A holder and an annuloplasty ring in combination, comprising:

an annuloplasty ring having a ring body including an internal drawstring extending over a portion of the circumference of said ring body and located adjacent an inner surface of said ring body;

a holder member having an outer circumferential surface to which said annuloplasty ring is mounted, said member having an annular recess into which said portion of said circumference of said annuloplasty ring containing said drawstring is inserted such that said drawstring lies within said annular recess.

2. A holder and annuloplasty ring according to claim 1 wherein a portion of said internal drawstring extends exterior to said annuloplasty ring body, further comprising snugger means for applying and maintaining tension on said drawstring.

3. A holder and annuloplasty ring according to claim 2 wherein said snugger means comprises means for applying and maintaining tension on said drawstring, while said annuloplasty ring is mounted to said holder member.

4. A holder and annuloplasty ring according to claim 2 wherein said snugger means comprises means for applying and maintaining tension on said drawstring, while said annuloplasty ring is dismounted from said holder member.

5. A holder and annuloplasty ring according to claim 2 wherein said snugger is removably mounted to said holder.

6. A holder and annuloplasty ring according to claim 5 wherein said portion of said drawstring extending exterior to said annuloplasty ring body is employed to removably mount said snugger means to said holder.

7. A holder and annuloplasty ring according to claim 6 wherein said holder further comprises a handle member extending from said holder member and having an annular groove, around which said drawstring is wrapped to retain said snugger means.

8. A holder and annuloplasty ring according to claim 1 wherein said holder member is provided with a recess located extending inward of said annular groove such that an opening is defined between said ring and said holder member.

9. A holder and an annuloplasty ring in combination, comprising:

an annuloplasty ring having a ring body including an internal drawstring extending over a portion of the circumference of said ring body;

a holder member having an outer circumferential surface to which said annuloplasty ring is mounted, and

snugger means for tensioning said drawstring to retain said annuloplasty ring on said holder member.

10. A holder and annuloplasty ring according to claim 9 wherein said snugger means comprises means for applying and maintaining tension on said drawstring, while said annuloplasty ring is mounted to said holder member.

11. A holder and annuloplasty ring according to claim 9 wherein said snugger means comprises means for applying and maintaining tension on said drawstring, while said annuloplasty ring is dismounted from said holder member.

12. A holder and annuloplasty ring according to claim 9 wherein said snugger is removably mounted to said holder.

13. A method of implanting an adjustable annuloplasty ring of the type employing a drawstring, comprising:

mounting said ring to a holder;

passing said drawstring through a suture snugger and mounting said snugger to said holder;

suturing said ring to a heart valve annulus;

removing said ring and said suture snugger from said holder;

employing said suture snugger to temporarily adjust the configuration of said ring by temporarily securing said drawstring; and

permanently securing said drawstring.

14. A method according to claim 13 further comprising the step of employing said drawstring to removably secure said suture snugger to said holder.
