BIMODAL TRICUSPID ANNULOPLASTY RING
First Claim
1. A tricuspid annuloplasty ring for use in a tricuspid valve repair procedure, the tricuspid annulus having peripheral landmarks as viewed from above in a clockwise direction of an antero-septal commissure, anterior leaflet, posterior commissure, posterior leaflet, postero-septal commissure, and septal leaflet, comprising a core made of a relatively rigid material defined by:
- a septal-anterior segment located around portions of the septal and anterior leaflets when implanted having a free first end and a second end;
an anterior-lateral segment located around portions of the anterior and posterior leaflets when implanted having a second end and a first end adjacent the second end of the septal-anterior segment;
a lateral-posterior segment located around the posterior leaflet when implanted having a second end and a first end adjacent the second end of the anterior-lateral segment; and
a posterior-septal segment located around the septal leaflet when implanted having a free second end and a first end adjacent the second end of the lateral-posterior segment,wherein the ring is configured such that a gap exists between the free first end of the septal-anterior segment and the free second end of the posterior-septal segment, the ring having a bimodal saddle shape having a first and second high point and a first and second low point, the first high point being located within the septal-anterior segment, the second high point being located within the lateral-posterior segment, the first low point being located within the anterior-lateral segment, and the second low point being located within the posterior-septal segment.

Abstract
A prosthetic remodeling tricuspid annuloplasty ring having two free ends can be configured to more accurately mimic native valve anatomy (e.g., shape) and movement during the cardiac cycle. A tricuspid ring can be provided with a substantially elliptical shape in the X-Y plane, and a bimodal saddle shape in the Z direction. The tricuspid ring can be configured to contract and expand during each cardiac cycle such that the area of the orifice and/or the diameter of the ring decrease with each contraction. Further, the elevation or non-planarity of the bimodal saddle shape can increase with each contraction. Movement of the tricuspid ring can vary in each different segment of the tricuspid ring. Tricuspid annuloplasty rings can be provided in a set, with changing ratios of diameter, changing out-of-plane static amplitudes, and changing amounts of dynamic movement in each different size of tricuspid ring.
