1. A method of endoscopic tubal ligation comprising the steps ofintroducing a distal end of an instrument assembly at an internal operative site in a patient'"'"'s body through a small size port providing communication with the internal operative site from externally thereof with a proximal end of the instrument assembly disposed externally of the operative site;

  • visualizing the internal operative site with an endoscope from externally of the internal operative site;

    grasping an anatomical tubular structure at the internal operative site with a grasping member of the instrument assembly disposed at the distal end;

    manipulating the grasping member from externally of the internal operative site to draw the anatomical tubular structure into a loop formation through a contractible ligature loop of filamentous ligature material of the instrument assembly disposed externally of the distal end;

    contracting the ligature loop around the loop formation of the anatomical tubular structure, from externally of the internal operative sites to form a ligature while the anatomical tubular structure remains grasped by the grasping member;

    cutting a segment of the loop formation proximally of the ligature with a cutting member carried by the grasping member;

    capturing the cut segment within the cutting member; and

    withdrawing the grasping member from the patient'"'"'s body to retrieve the cut segment externally of the patient'"'"'s body.
