  • an elongate flexible catheter;

    a control housing at a proximal end of the catheter;

    a needle opening at a distal end of the catheter;

    two or more anchor assemblies within the catheter, with each anchor assembly including a first anchor attached to a second anchor via a suture, and with the first and second anchors each having a proximal tubular collar attached to a distal tubular collar by one or more flexible elements, with the suture extending through the proximal and distal collars of the first and second anchors;

    with the first and second anchors temporarily interlocked via a first pair of curved tabs on the distal tubular collar of the first anchor engaged with a second pair of curved tabs on the proximal tubular collar of the second anchor; and

    with the first and second pairs of curved tabs adapted to interlock the first and second anchors when they are within the catheter, and to unlock the first and second anchors from each other when the first anchor is moved out of the catheter.
