ABSTRACT:
Apparatus for needle grasping and performing a second modality comprising a sheath axially extending between distal and proximal ends thereof. The device includes an inner hollow tube with a slot formed therein for receiving a needle at the distal end. Retraction and extension of the inner tubular member relative to the sheath enable the grasping and releasing of a suture needle received in the slot. A handle is provided at the proximal end of the apparatus for selectively extending and retracting the inner tube relative to the sheath and for retaining the inner tube in its extended and retracted positions. A second switch can be provided in the handle to actuate a catheter slidably inserted through the inner tube to perform a second therapeutic modality. The catheter preferably includes a distal bight that forms a loop when extended from the distal end of the sheath for facilitating intracorporeal knot tying thereat. The catheter includes a lumen therethrough for receiving suture thread for use at the distal end of the sheath.
