Abstract
The invention provides an apparatus and method for tissue ligation and transection. In a preferred embodiment, the apparatus comprises a shaft with a slot at the distal end in which a tissue structure may be positioned. A suture is mounted about the periphery of the slot with a free end of the suture on a first side of the slot and a knotted loop on a second side of the slot. The free end of the suture is retrieved and threaded through knotted loop so as to form a ligature surrounding the tissue structure. The free end is drawn proximally to tighten the ligature, and the knotted loops are cinched tight to lock the ligature in position. A blade slidably mounted in the shaft may be advanced to transect the tissue structure adjacent or between ligatures. A sleeve for compressing tissue within the slot during ligation, as well as electrodes for cauterizing the tissue, are also disclosed.
