<p>A suturing apparatus (10b) is adapted for joining two objects (281, 283) which define a near side (27b), and a far side (30b). The apparatus includes an elongate support structure (47b) having a working channel (54b). The structural support is adapted to be positioned over a guide wire (21b) extending between the two objects. Removal of the guide wire (21b) permits use of a stylet for positioning a suture (291) to extend within the working channel (54b) from a proximal to a distal end. A pair of hooks (70b, 72b) are movable from a proximal position at the proximal end of the support structure through the objects, and a pair of slots (167b, 170b) in the support structure, to a distal position wherein the hooks (70b, 72b) engage the suture (291) within the working channel (54b) at the distal end of the support structure. The actuator (285, 287) is then operable to move the hooks (70b, 72b), the engaged suture (291) from the distal position to the proximal position in order to facilitate tying of the suture, and joining the two objects.</p> |
