Abstract

An annuloplasty ring having a three-dimensional discontinuous form generally arranged about an axis with two free ends that are axially offset. The ring is particularly suited for repair of the tricuspid valve, and more closely conforms to the annulus shape. The ring is more flexible in bending about radially extending axes than about the central axis. The ring may have an inner structural support covered by a pliable sleeve and/or a fabric tube. The structural support may have a varying cross-section, such as a C-shaped cross-section in a mid-section between two free ends and a rectangular cross-section at the free ends. A deliver template having a mounting ring with about the same shape as the ring facilitates implant, and may be releasably attached to a delivery handle. The deliver template may include a plurality of cutting guides for releasably attaching the annuloplasty ring thereto while presenting maximum outer surface area of the ring. The template may have an outwardly-facing groove to receive and retain the ring.

Claims (33)

1. An annuloplasty ring, comprising:
a ring body generally arranged about an axis and being discontinuous so as to define two free ends, wherein the ring body has a relaxed configuration following a three-dimensional path such that the free ends are axially offset from an annulus reference plane through a midpoint of the ring body.
2. The annuloplasty ring as in claim 1, wherein the two free ends are axially offset from each other.
3. The annuloplasty ring as in claim 2, wherein the distance that the two free ends are axially offset from each other is between about 2-15 mm.
4. The annuloplasty ring as in claim 1, wherein the ring is adapted to reinforce the tricuspid annulus and has a curvilinear anterior side ending in one of the free ends, a relatively straight septal side ending in the other of the free ends, and a curvilinear posterior side extending between the anterior and septal sides, the posterior side being shorter and having a smaller radius of curvature than the anterior side.
5. The annuloplasty ring as in claim 1, wherein the ring body comprises an inner structural support of multiple bands of elastic material.
6. The annuloplasty ring as in claim 5, further including a low friction material interposed between each two adjacent bands.
7. The annuloplasty ring as in claim 5, wherein the multiple bands are embedded in a matrix of a pliable material.
8. The annuloplasty ring as in claim 7, wherein the pliable material is molded silicone.
9. The annuloplasty ring as in claim 8, wherein there are two concentrically disposed bands embedded in the matrix of pliable material.
10. The annuloplasty ring as in claim 5, wherein each of the multiple bands of elastic material has a relatively wider radial dimension than its axial dimension.
11. The annuloplasty ring as in claim 1, wherein the ring body comprises an inner structural support band surrounded by a pliable matrix, and wherein the matrix includes a tubular inner portion that surrounds the band and an outer flange through which implantation sutures can pass.
12. The annuloplasty ring as in claim 11, wherein the outer flange is curved so as to be convex on its outer surface.
13. The annuloplasty ring as in claim 11, wherein the outer flange is connected to the inner tubular portion with a plurality of circumferentially spaced apart radial walls so as to create a celled structure.
14. The annuloplasty ring as in claim 1, wherein the ring body comprises an inner structural support having two free ends, a curvilinear anterior side ending in one of the free ends, a relatively straight septal side ending in the other of the free ends, and a curvilinear posterior side extending between the anterior and septal sides, wherein a majority of the posterior side lies generally in a plane perpendicular to the axis.
15. The annuloplasty ring as in claim 14, wherein the two free ends are both axially offset in the same direction from the plane.
16. The annuloplasty ring as in claim 14, wherein the structural support has a cross-section that changes around its length.
17. The annuloplasty ring as in claim 16, wherein the cross-section is partly C-shaped.
18. The annuloplasty ring as in claim 17, wherein the C-shaped part of the cross-section is in the posterior side, and wherein the two free ends are rectangular.
19. An annuloplasty ring, comprising:
a three-dimensional ring body generally arranged about a central axis and being discontinuous so as to define two free ends, wherein the ring body has a construction that renders it more flexible in bending at the two free ends than in a midpoint thereof.
20. The annuloplasty ring of claim 19, wherein the ring body comprises an inner structural support covered by a flexible suture-permable outer layer.
21. The annuloplasty ring as in claim 20, wherein the outer layer is silicone.
22. The annuloplasty ring as in claim 21, wherein the inner structural support comprises two concentrically disposed bands.
23. The annuloplasty ring as in claim 19, wherein the ring body comprises an inner structural support having two free ends, a curvilinear anterior side ending in one of the free ends, a relatively straight septal side ending in the other of the free ends, and a curvilinear posterior side extending between the anterior and septal sides, wherein a majority of the posterior side lies generally in a plane perpendicular to the axis.
24. The annuloplasty ring as in claim 19, wherein the two free ends are both axially offset from an annulus reference plane through a midpoint of the ring body.
25. The annuloplasty ring as in claim 19, wherein the structural support has a cross-section that changes around its length.
26. The annuloplasty ring as in claim 25, wherein the cross-section is partly C-shaped.
27. The annuloplasty ring as in claim 26, wherein the C-shaped part of the cross-section is in a midpoint of the ring body, and wherein the two free ends have a cross-section that renders them more flexible in bending about the axis.
28. An annuloplasty ring template, comprising:
a rigid body having a peripheral mounting ring generally arranged about an axis and being discontinuous so as to define two free ends, the mounting ring following a three-dimensional path such that the free ends are axially offset from an annulus reference plane through a midpoint of the ring body.
29. The annuloplasty ring template of claim 28, wherein the template includes a central platform to which the peripheral mounting ring is connected via a plurality of generally radially extending spokes.
30. The annuloplasty ring template of claim 29, further including a handle-receiving hub extending generally axially from the central platform.
31. The annuloplasty ring template of claim 28, wherein the peripheral mounting ring extends about three-quarters circumferentially about the axis.
32. The annuloplasty ring template of claim 28, wherein the peripheral mounting ring defines a radially outwardly opening groove therein for receiving an annuloplasty ring.
33. The annuloplasty ring template of claim 28, further including a plurality of cutting guides provided on the peripheral mounting ring, wherein a pair of through holes in the mounting ring are provided on either side of each cutting guide such that a length of suture may extend through an annuloplasty ring positioned on the outside of the mounting ring, through one of the holes, over the cutting guide, through the other hole, and back into the annuloplasty ring.
