Abstract
A prosthetic tricuspid remodeling annuloplasty ring having two free ends and at least one inward bow to help reduce chordal tethering. The ring may have segments corresponding to the anterior, posterior and septal leaflets, with inward bows located adjacent one, two or all leaflets. Convex corners separate the concave inward bows, with inflection points therebetween. The ring has a semi-rigid inner body covered by fabric or a suture interface such as silicone and fabric.

22. A prosthetic tricuspid annuloplasty ring, comprising:
a ring body peripherally arranged about an axis and being discontinuous so as to define two free ends at a break in continuity around the ring body, wherein a plan view of the ring body along the axis defines, in sequence; a first free end; a first septal segment adapted to attach to the tricuspid annulus adjacent a portion of the septal leaflet; an anterior segment adapted to attach to the tricuspid annulus adjacent the anterior leaflet; a posterior segment adapted to attach to the tricuspid annulus adjacent the posterior leaflet; a second septal segment adapted to attach to the tricuspid annulus adjacent a portion of the septal leaflet; and a second free end, wherein one or more of the first septal segment, anterior segment, posterior segment, and second septal segment is at least partly concave defining an inward bow. - View Dependent Claims (23, 24, 25, 26)
