摘要：
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, 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 atrioventricular node by the annuloplasty ring when implanted. In another embodiment, at the annuloplasty ring is configured to include an assembly that facilitates selective adjustment of a segments respective length and/or shape. The adjustment of the length of one of the ring segments 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.
