Patent attributes
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.
