Abstract
Abstract A suture driver for clamping a suture in the hollow passage and a recessed channel thereof and manipulating the suture to and from a surgical site. The driver includes an outer member tube having a closed and pointed distal end for percutaneous introduction into the body of a patient. The outer tube also includes a recessed channel positioned proximal the closed distal end of the hollow passage extending longitudinally therein and for receiving the suture therein. An inner rod is positioned in the passage of the outer tube and has a clamping surface at the distal end thereof for engaging a suture positioned in the recessed channel. The inner rod is slid through the recessed channel to clamp the suture in the hollow passage of the outer tube against another clamping surface at the distal end of the tube. A handle positioned at the proximal end of the outer tube and inner rod is manipulated to slide the inner rod through the recessed channel and clamp the suture in the hollow passage between the two clamping surfaces. The inner rod positioned through the recessed channel also reinforces the outer tube during percutaneous introduction into the patient.
