Abstract

An annuloplasty system including an annuloplasty prosthesis and a holder for the prosthesis.

Claims

1. A system for repair of a patient'"'"'s mitral valve comprising:

a holder having a first side, a second side generally opposite the first side, the holder defining a central portion that generally defines a radial direction relative to the center portion, and an outer circumferential surface corresponding generally to the configuration of a heart mitral valve annulus, the holder comprising a substantially transparent polymer;

a rigid annuloplasty ring having a metal insert and an outermost circumferential surface, the annuloplasty ring being located adjacent to and extending along the outer circumferential surface of the holder;

a cuttable suture adapted to releasably secure the rigid annuloplasty ring to the outer circumferential surface of the holder, the cuttable suture including at least a portion thereof that is permanently fixed in position relative to the holder even after being cut;

the first side of the holder having slots adapted to permit cutting of the cuttable suture prior to removing the rigid annuloplasty ring from the holder, and

wherein no portion of the holder is located radially away from the central portion and the outermost circumferential surface of the rigid annuloplasty ring.

2. A system according to claim 1 wherein the holder is generally in the form of an oblate ring.

3. A system according to claim 1 wherein the holder comprises first and second holder components.

4. A system according to claim 1 further comprising a handle adapted to be releasably associated with the holder by virtue of screw threads.

5. A system according to claim 4 wherein the handle is snap fit to the holder.

6. A system according to claim 1 wherein the second side of the holder includes at least two pins projecting therefrom to assist in holding said ring to said holder.

7. A system according to claim 6 wherein said pins do not pierce said ring.

8. A system for repair of a patient'"'"'s mitral valve comprising:

a holder having a first side, a second side generally opposite the first side, the holder defining a central portion that generally defines a radial direction relative to the center portion, and an outer circumferential surface corresponding generally to the configuration of a heart mitral valve annulus, the holder comprising a first holder component and a second holder component that are movably disposed to one another;

a rigid annuloplasty ring having a metal insert and an outermost circumferential surface, the annuloplasty ring being located adjacent to and extending along the outer circumferential surface of the holder;

a cuttable suture adapted to releasably secure the rigid annuloplasty ring to the outer circumferential surface of the holder by permitting movement of the first holder component with respect to the second holder component, the cuttable suture adapted to be permanently connected to the holder even after being cut;

the first side of the holder having slots adapted to permit cutting of the cuttable suture prior to removing the rigid annuloplasty ring from the holder, and

wherein no portion of the holder is located radially away from the central portion and the outermost circumferential surface of the rigid annuloplasty ring.
