Abstract: The present disclosure relates to a ligating instrument and end effector assemblies for use in laparoscopic tubal ligation procedures. The ligating instrument includes an integral grasping assembly and an integral end effector actuator and is configured to perform a ligating procedure by operation of a single hand of a user. The ligating instrument includes an integral grasper assembly for grasping a tubular tissue section and removable end effector or suture deployment mechanism for holding open a suture to be positioned about the tubular section. The grasper is configured to draw the tubular section into the open loop of suture material and cinch the suture material about the tubular tissue section. A rotator knob may be provided to orient grasper members associated with the grasper assembly relative to the tissue section.

Abstract: A surgical loop delivery device is disclosed in parent disclosures Ser. No. 09/071,811 and U.S. Pat. No. 5,766,217. This device is improved to permit tissue targets larger than the device to be ligated while also maintaining a clear sight path between the surgeon and the target. The surgical loop is also stable during the procedure.
