Abstract: 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.

Abstract: Annuloplasty rings are employed to treat heart valve defects, such as regurgitation. Synching the heart tissue to the ring restores the valve opening to its approximate original size and operating efficiency. Adjustable annuloplasty rings allow for a proper degree of synching both during open heart surgery and over the patient's lifetime. A subcutaneous port may be coupled to an adjustable annuloplasty ring such that an external activation energy generator can be used to heat the adjustable annuloplasty ring and thereby adjust the size of the annuloplasty ring.

Abstract: Annuloplasty rings reduce or eliminate tricuspid regurgitation and/or tricuspid annulus dilation. An adjustable annuloplasty device includes a ring body having a first free end and a second free end. The ring body includes a shape memory material to provide a shape change to the adjustable annuloplasty device upon activation. The ring body includes a first segment including the first free end and following a curved path corresponding to an anterior leaflet region of a tricuspid annulus, a second segment following a curved path corresponding to a posterior leaflet region of the tricuspid annulus, and a third segment including the second free end and at least partially following a linear path corresponding to a portion of a septal leaflet region of the tricuspid annulus. Activation of the shape memory material changes a dimension of the adjustable annuloplasty device.
