Annuloplasty rings and methods for heart valve repair
First Claim
1. A tricuspid annuloplasty ring configured for implantation in a tricuspid valve annulus having an anterior annulus section, a septal annulus section and a posterior annulus section, the annuloplasty ring comprising:
- a triangular shaped continuous body having an anterior segment, a septal segment and a posterior segment, wherein each of the anterior, septal and posterior segments are geometrically shaped to conform to the anatomic shape of the anterior, septal and posterior sections of tricuspid valve annulus, wherein at least one of the anterior segment, the septal segment, and the posterior segment comprises a plurality of sub-segments, wherein a one of the plurality of sub-segments is detachable to create a triangular shaped discontinuous body to facilitate implantation, the triangular shaped continuous body having a first connection between the anterior segment and the septal segment, a second connection between the septal segment and the posterior segment, and a third connection between the anterior segment and the posterior segment, triangular shaped continuous body being flexible at at least one of the first connection, the second connection, and the third connection and rigid elsewhere,wherein the ring further comprises an adjustment device attached to the ring, wherein the adjustment device comprises;
a gearbox; and
at least one flexible wire, wherein the at least one flexible wire connects the gearbox to the at least one of the flexible connections.

Abstract
An annuloplasty ring, configured for implantation in the annulus of a heart valve, comprising multiple segments each of which are geometrically shaped from a three dimensional perspective to conform to the anatomic shape of the valve annulus. In one embodiment, at least one of the multiple segments of the annuloplasty ring is configured to facilitate a reduction of tension on heart valve tissue and eliminate a substantial portion of potential pressure or force that may be applied to the atrio-ventricular node by the annuloplasty ring when inserted into a heart valve. In another embodiment, at least one of the multiple segments of the annuloplasty ring are configured to include an assembly that facilitates selective adjustment of a segment'"'"'s respective length and/or shape. The adjustment of the length of one of the ring segment'"'"'s results in an adjustment of at least one angle between at least one set of other ring segments, thereby causing an adjustment to the geometric characteristics of the ring.
