1. Apparatus comprising:

  • a torque-delivering cable, which comprises a first coupling, wherein the torque-delivering cable and the first coupling are shaped so as to collectively define a first passage therethrough;

    a tissue anchor, which comprises a tissue-engaging element and a second coupling, which second coupling is shaped so as to define a second passage therethrough open to a space surrounded by the tissue-engaging element, wherein the first and the second couplings are interlockingly coupleable to each other; and

    an elongate longitudinal locking element, which is configured to be advanceable into the space surrounded by the tissue-engaging element, and which;

    when reversibly disposed in the first and the second passages, maintains coupling together of the first and the second couplings, andwhen withdrawn from the second passage, allows decoupling of the first and the second couplings from each another,wherein the torque-delivering cable is configured such that rotation thereof, when the first and the second couplings are coupled together, rotates the first and the second couplings, and thereby the tissue anchor.
