1. A wound closure apparatus for suturing a wound in a body wall, comprising:

  • a cannula having an axis extending between a proximal end and a distal end;

    a handle disposed at the proximal end of the cannula;

    a catheter coupled to the distal end of the cannula, the catheter being sized and configured to extend through the wound in the body wall;

    a pair of needles movable from a proximal position in proximity to the cannula to a distal position in proximity to the catheter, each of the needles having a proximal end and a distal end;

    a suture having a first end, a second end, and a suture loop disposed between the first and second ends;

    a suture manipulator in the catheter for containing the suture ends and moving the suture ends relative to the needles;

    an actuator mounted for reciprocation in cannula, the actuator includingfirst means for cooperating with the needles to move the needles from the proximal position to the distal position, andsecond means for cooperating with the suture manipulator to move the suture ends into threading engagement with the needles.
