Abstract
An instrument assembly for performing anatomical tissue ligation includes a passage defining member having a distal end for being disposed at an internal operative site, a proximal end for being disposed externally of the internal operative site and a passage between the distal and proximal ends. A grasping member is disposed at the distal end of the passage defining member for grasping anatomical tissue at the internal operative site. A contractible ligature loop of filamentous ligature material is carried by the passage defining member and is disposed externally of the distal end thereof for positioning around the anatomical tissue grasped by the grasping member. The ligature loop is contractible, from externally of the internal operative site, around the anatomical tissue to form a ligature allowing a complete anatomical tissue ligation to be performed with a single instrument assembly.
