Three-dimensional annuloplasty ring
First Claim
1. A tricuspid annuloplasty ring sized and configured for attaching to an interior wall of and reinforcing the tricuspid annulus, comprising:
- a relatively rigid single piece inner body defining an elongated path, the inner body generally arranged about an axis and being split and discontinuous so as to define two free ends with a break therebetween and no inner body therebetween, the inner body having, in plan view, a curvilinear anterior side terminating in one of the free ends, a relatively straight septal side terminating in the other of the free ends, and a curvilinear posterior side extending between the anterior and septal sides, wherein the inner body is sized to extend within and around the tricuspid valve annulus, andwherein the inner body has a radial cross-section that gradually changes around its length and is radially enlarged in a mid-point in comparison to the two free ends.

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 relatively rigid inner body defining an elongated path, the inner body generally arranged about an axis and being split and discontinuous so as to define two free ends with a break therebetween and no inner body therebetween, the inner body having, in plan view, a curvilinear anterior side terminating in one of the free ends, a relatively straight septal side terminating in the other of the free ends, and a curvilinear posterior side extending between the anterior and septal sides, wherein the inner body is sized to extend within and around the tricuspid valve annulus, and wherein a length of the posterior side lies generally in a reference plane perpendicular to the axis, and wherein in a relaxed, non-stressed state of the inner body, both free ends curve away from the reference plane in the same direction so as to be offset therefrom. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
