摘要: Apparatus, systems, and methods are provided for repairing heart valves through percutaneous transcatheter delivery fixation of annuloplasty rings to valves. An ring includes an outer hollow body member including a plurality regions. Adjacent regions cooperate with one another change the from elongate insertion geometry annular operable geometry. coupled by biasing element or stepped connector allow expansion expanded state contraction contracted in The also internal anchor located at least partially within having anchors configured attach tissue valve annulus. angled closure lock allows coupling ends apex D-shape
