Instrument assemblies for performing anatomical tissue ligation
First Claim
1. An instrument assembly for performing anatomical tissue ligation at an internal operative site in a patient'"'"'s body comprisingan elongate passage defining member having a distal end for being disposed at an internal operative site in the body, a proximal end for being disposed externally of the internal operative site and a passage extending longitudinally therethrough;
- a pair of grasping members carried by said passage defining member and disposed at said distal end, said grasping members being selectively movable, from said proximal end of said passage defining member, between an open position to receive anatomical tissue at the internal operative site therebetween and a closed position to grasp the anatomical tissue therebetween;
a ligature supply disposed in said passage defining member and having a preformed, contractible ligature loop of filamentous ligature material disposed at said distal end for being positioned around the anatomical tissue grasped by said grasping members, said ligature loop being contractible, from said proximal end of said passage defining member, around the anatomical tissue to form a ligature; and
a pair of cutting members carried by said grasping members, respectively, said cutting members being operable, from said proximal end of said passage defining member, to cut a segment of the anatomical tissue proximally of the ligature, said cutting members being configured to capture the cut segment of the anatomical tissue therebetween for withdrawal and retrieval of the cut segment from the patient'"'"'s body.

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.
