Adjustable annuloplasty device with alternating peaks and troughs
First Claim
1. Apparatus for use at a valve of a heart of a subject, the apparatus comprising an implant, the implant comprising:
- a ring, comprising (i) a plurality of struts arranged in a pattern of alternating peaks and troughs, and (ii) a plurality of hinges, the ring circumscribing a central axis,at least one hinge of the plurality of hinges being disposed at each trough,each strut having a first end-portion and a second end-portion,each peak defined by convergence of a pair of adjacent first end-portions disposed at an angle with respect to each other, andeach trough defined by convergence of a pair of adjacent second end-portions;
a plurality of adjustment elements, each of the adjustment elements being rotatably coupled to a respective pair of adjacent first end-portions such that rotation of the adjustment element with respect to the pair changes the angle at which the adjacent first end-portions of the pair are disposed with respect to each other; and
a plurality of anchors, each anchor;
having a longitudinal axis,configured to be driven along the longitudinal axis into tissue of the heart, andcoupled to the ring at a respective trough via the at least one hinge in a manner that facilitates;
movement of the anchor along the longitudinal axis with respect to the trough, anddeflection of the longitudinal axis with respect to the central axis.

Abstract
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.

17. A system comprising:
-
an implant comprising a ring having a plurality of struts arranged in a pattern of alternating peaks and troughs, each strut of the plurality of struts having a first end-portion and a second end-portion, each peak defined by convergence of a pair of adjacent first end-portions disposed at an angle with respect to each other, and each trough defined by convergence of a pair of adjacent second end-portions, the ring circumscribing a central axis; a plurality of adjustment elements, each of the adjustment elements being rotatably coupled to a respective pair of adjacent first end-portions such that rotation of the adjustment element with respect to the pair changes the angle at which the adjacent first end-portions of the pair are disposed with respect to each other; and a plurality of anchors, each anchor; having a longitudinal axis, configured to be driven along the longitudinal axis into tissue of the heart, and coupled to the ring at a respective trough in a manner that facilitates; movement of the anchor along the longitudinal axis with respect to the trough, and deflection of the longitudinal axis with respect to the central axis.
