<p>A system method for reconfigurating an atrioventricular heart valve. The system comprises a partial or complete annuloplasty ring (13, 43, 51, 61) having a size and shape proportioned to reconfigure a heart valve of a patient that has become in some way incompetent, a pair of trigonal sutures (67) or implantable anchors, and a plurality of staples (69) having pairs of legs that are sized and shaped for association with the ring at spaced locations along the length thereof. The system permits relative axial movement between the staples (69) and the ring, whereby a patient's heart valve can be reconfigured in a manner that does not deter subtle shifting of the native valve components. Staples may be made of a shape-memory alloy material and may have legs that have free ends that form an interlocking orientation following implantation Annuloplasty ring may be a complete or partial ring and may be fenestrated having a plurality of spaced-apart elongated windows (63). A partial ring may have a pair of aligned holes at one end which fit over posts of anchors. An alternate method routes a flexible wire which may be of shape-memory material through the bights of pre-implanted staples and permits adjustment of the effective length of a partially installed ring.</p> |
