Abstract
A device for delivering a loop of suture material for use in endoscopic ligation is described. The device has a pair of coaxial slidable cylindrical tubes. The outer tube contains a hook for snaring the free end of the suture material; the inner tube contains a groove for retaining the suture loop circumferentially about the bore of the inner tube and also a hole beyond which the slip knot cannot move proximally. When the inner tube is pushed in a distal direction relative to the outer tube, the loop is pulled off the groove and is tightened. In use a grasping tool is inserted through the bore of the inner tube and is used to grasp a piece of tissue to be ligated. The device is then deployed, ligating the tissue piece.
