1. 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.
