Abstract

A suturing apparatus is adapted for joining two objects which define a near side and a far side. The apparatus includes an elongate support structure having a working channel and an axis extending between a proximal end and a distal end. The structural support is adapted to be positioned over a guidewire extending between the two objects, in an operative position wherein the proximal end is disposed on the near side and the distal end as disposed on the far side. Removal of the guidewire permits use of a stylet for positioning a suture to extend within the working channel from the proximal end to the distal end. A pair of hooks are movable from a proximal position at the proximal end of the support structure through the objects and a pair of slots in the support structure, to a distal position wherein the hooks engage the suture within the working channel at the distal end of the support structure. The actuator is then operable to move the hooks and the engaged suture from the distal position to the proximal position in order to facilitate tying of the suture and joining of the two objects. Alternatively, suture loops can be carried through the objects by unidirectional hooks and into the working channel. The hooks can then be withdrawn leaving the suture loops in the working channel where they can be engaged by a snare and withdrawn proximally between the two objects. Suturing pledgets can be added to the suturing apparatus prior to operative disposition, and a backing member can be provided to support at least the pledgets when the hook passes through the object.
