Abstract
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.
