Abstract
A method is provided, including positioning a tissue anchor along an annulus of a patient'"'"'s valve. The anchor includes a distal tissue coupling element including (1) a pointed tip to puncture tissue of the annulus, and (2) a longitudinal element extending proximally from the distal tissue coupling element and including an implant-restraining element at a proximal end of the longitudinal element. The tissue coupling element couples the anchor to the patient'"'"'s tissue. The method includes restraining a valve-repair implant from separating from the annulus by the implant-restraining element, by, subsequently to the positioning of the anchor, facilitating movement between (1) the implant, and (2) the longitudinal element of the anchor, such that the implant-restraining element extends around at least a portion of the implant. The longitudinal element facilitates sliding between the implant and the tissue anchor. Other applications of the present invention are also described.

69. A method, comprising:
-
positioning along an annulus of a valve of a patient at least one tissue anchor including; a distal tissue coupling element including a pointed tip configured to puncture tissue of the annulus, the tissue coupling element being configured to couple the tissue anchor to the cardiac tissue of the patient; and a longitudinal element including an implant-restraining element at a proximal end of the longitudinal element, the longitudinal element extending proximally from the distal tissue coupling element; and restraining a valve-repair implant from separating from the annulus by the implant-restraining element, by, subsequently to the positioning of the at least one tissue anchor, facilitating movement between (1) the valve-repair implant, and (2) the longitudinal element of the tissue anchor, such that the implant-restraining element extends around at least a portion of the implant, the longitudinal element facilitating a slidable coupling arrangement between the valve-repair implant and the tissue anchor. - View Dependent Claims (70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84)
