An implant, disposed within a catheter, comprises a ring, anchors, and adjustment elements. The ring comprises struts arranged in a pattern of alternating peaks and troughs. Each strut has a first end-portion and a second end-portion. Each peak is defined by convergence of adjacent first end-portions disposed at an angle with respect to each other, and each trough is defined by convergence of adjacent second end-portions. Each of the anchors has a longitudinal axis, is coupled to the ring at a respective trough, and is configured to be driven along the longitudinal axis with respect to the trough and into tissue of the heart. Each of the adjustment elements is configured to adjust an angular disposition between a respective pair of the struts. A first adjustment element is coupled to its pair, and a second adjustment element is coupled to its pair distal to the first adjustment element.

Adjustable annuloplasty device with alternating peaks and troughs

An implant that includes a ring, anchors, and adjustment elements is advanced to a subject's heart valve. The ring includes hinges, and struts arranged in a pattern of alternating peaks and troughs. The ring circumscribes a central axis. At least one hinge is disposed at each trough. Each strut has a first end-portion and a second end-portion. Each peak is defined by convergence of adjacent first end-portions. Each trough is defined by convergence of adjacent second end-portions. Each anchor has a longitudinal axis. Within the heart, the longitudinal axis of at least one of the anchors is deflected with respect to the central axis, and each of the anchors is driven along its longitudinal axis with respect to the trough and into tissue of the heart. Subsequently, tissue of the heart is contracted by rotating the plurality of adjustment elements. Other embodiments are also described.

Apparatus is provided, comprising a ring, comprising a plurality of struts arranged in a pattern of alternating peaks and troughs, each strut having a first end-portion and a second end-portion, each peak defined by convergence of adjacent first end-portions disposed at an angle with respect to each other, and each trough defined by convergence of adjacent second end-portions. The apparatus also comprises a plurality of anchors. Each anchor has a longitudinal axis, is configured to be driven along the longitudinal axis into tissue of the heart, and is coupled to the ring at a respective trough in a manner that facilitates (i) movement of the anchor along the longitudinal axis with respect to the trough, and (ii) deflection of the longitudinal axis with respect to the trough.
