1. An adjustment tool for adjusting the size of an annuloplasty ring, the tool comprising:

  • a housing having a distal end and a proximal end, the housing having an elongated central opening, a first bore extending through the distal end of the housing in communication with the opening, and a second bore extending through the proximal end in communication with the opening;

    an externally threaded hollow barrel non-rotationally arranged within the opening of the housing, the barrel having an axis in alignment with the first and second bores;

    an internally threaded knob rotationally engaged about and longitudinally moveable along the barrel and along the housing within the opening, the knob having a rotational axis in alignment with the axis of the barrel; and

    a central shaft extending along the rotational axis through the first bore and through the barrel into the knob, the shaft having a portion attached to the knob;

    whereby rotation of the knob about the barrel causes rotation of the shaft about the rotational axis and longitudinal movement of the knob along the barrel and along the housing within the opening.
