Abstract
An annuloplasty system including an annuloplasty prosthesis and a holder for the prosthesis.
Claims19
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 more elements
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.
2 more elements
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.
