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

대표청구항 ▼

We claim: 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, the first holder component further comprising at least one outwardly extending member and the first holder component being deformable from a mount configuration to a reduced circumference configuration; an annuloplasty prosthesis, located adjacent to and extending at least partially around the circumferential surface of the first holder component in the mount configuration such that the outwardly extending member extends alongside a lower surface of the prosthesis, preventing the prosthesis from moving downward and off of the first holder component; a second holder component, coupled to and extending above the first holder component, movable upwardly relative to the first holder component and comprising means for preventing deformation of the first holder component to the reduced circumference configuration until movement of the second holder component relative to the first holder component; and wherein the second holder component is releasably secured adjacent to the first holder component by cuttable sutures. 2. A system as in claim 1 wherein the first holder component is an open ring with spaced ends and wherein the second holder component comprises a projection locatable between the spaced ends to prevent movement of the spaced ends toward one another and reduction of the circumference of the first holder component. 3. A system as in claim 2, wherein the projection extends downwardly from the second holder component and exits its location between the spaced ends upon upward movement of the second holder component. 4. A system as in claim 1 wherein the at least one outwardly extending projection comprises a series of spaced projections, located along the circumferential surface. 5. A system as in claim 1 wherein the at least one outwardly extending projection comprises a single elongated projection, extending along the circumferential surface. 6. A system as in claim 1 wherein the at least one outwardly extending projection comprises a lower edge of a groove extending along the circumferential surface. 7. 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, the first holder component comprising at least one outwardly extending member; and a suture cutter comprising a cutter element on the first holder component that is movable relative to another element of the first holder component; an annuloplasty prosthesis, located adjacent to and extending at least partially around the circumferential surface such that the outwardly extending member extends alongside a lower surface of the prosthesis, preventing the prosthesis from moving downward and off of first holder component; and a cuttable suture, holding the annuloplasty prosthesis adjacent the circumferential surface and passing through the suture cutter. 8. A system as in claim 7 wherein the first holder component is deformable to display a reduced circumference. 9. A system as in claim 8 wherein the cutter element is movable relative to the other element for cutting the suture responsive to deformation of the first holder component. 10. A system as in claim 9 wherein the first holder component is an open ring having spaced ends and wherein the cutter is coupled to the spaced ends and comprises means for cutting the suture responsive movement of the spaced ends toward one another. 11. A system as in claim 10, further comprising a second holder component, coupled to and extending above the first holder component, movable upwardly relative to the first holder component and comprising means for preventing movement of the spaced ends toward one another until upward movement of the second holder component. 12. A system as in claim 11 wherein the second holder component comprises a projection locatable between the spaced ends to prevent movement of the spaced ends toward one another and reduction of the circumference of the first holder component. 13. A system as in claim 7, further comprising a second holder component, coupled to and extending above the first holder component, movable upwardly relative to the first holder component and comprising means for preventing deformation of the first holder component until upward movement of the second holder component. 14. 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, the first holder component being an open ring comprising an arcuate element extending from a first end to a second end, the first and second ends being spaced from one another and movable toward one another to reduce the ring's circumference and comprising at least one outwardly extending member; and an annuloplasty prosthesis, located adjacent to and extending at least partially around the circumferential surface such that the outwardly extending member extends alongside a lower surface of the prosthesis. 15. A system as in claim 14, wherein the first holder component comprises engaging means located at the ends of the spaced ring ends for facilitating movement of the spaced ends toward one another. 16. A system as in claim 15, wherein the engaging means comprises projections extending interiorly of the open ring. 17. A system as in claim 14, further comprising a second holder component, coupled to and extending above the first holder component, movable upwardly relative to the first holder component and comprising means for preventing movement of the spaced ends toward one another holder component until upward movement of the second holder component. 18. A system as in claim 17 wherein the second holder component comprises a projection locatable between the spaced ends to prevent movement of the spaced ends toward one another and reduction of the circumference of the first holder component. 19. A system as in claim 18, wherein the projection extends downwardly from the second holder component and exits its location between the spaced ends upon upward movement of the second holder component.
