PERCUTANEOUS TRANSCATHETER REPAIR OF HEART VALVES

摘要

Apparatus, systems, and methods are provided for repairing heart valves through percutaneous transcatheter delivery and fixation of annuloplasty rings to heart valves. An annuloplasty ring includes an outer hollow member including a plurality of segments. Adjacent segments cooperate with one another to change the outer hollow member from an elongate insertion geometry to an annular operable geometry. The annuloplasty ring also includes an internal anchor member located at least partially within the outer hollow member. The internal anchor member includes a plurality of anchors configured to attach the annuloplasty ring to tissue of a heart valve annulus. The internal anchor member is configured to move the plurality of anchors with respect to a plurality of windows in the outer hollow member to selectively deploy the plurality of anchors through the respective windows.
