ABSTRACT:
A ligating instrument for forming ligatures at an internal operative site in the body includes an instrument body having a distal end for positioning at the operative site, a proximal end for positioning externally of the body and a lumen between the distal and proximal ends. A ligature supply including a plurality of preformed, contractible ligature loops of filamentous ligature material is disposed in the lumen. Each of the ligature loops has a fixed knotting element and a movement permitting knotting element permitting movement of the ligature material relative thereto to reduce the size of the ligature loops around anatomical structure. The ligature supply is movable distally relative to the instrument body to move a ligature loop through the distal end to deploy the ligature loop externally of the instrument body for positioning around anatomical structure. An operating member carried by the instrument body is operable to move the ligature material proximally relative to the instrument body to reduce the size of the ligature loop around the anatomical structure to form a ligature while the movement permitting knotting element of the ligature loop is maintained externally of the instrument body. A method of forming ligatures includes the steps of withdrawing a ligature loop of filamentous material through a distal end of an instrument body, positioning the ligature loop around anatomical structure, moving an operating member to move the filamentous material proximally relative to the instrument body to reduce the size of the ligature loop around the anatomical structure to form a ligature and withdrawing another ligature loop of the ligature supply through the distal end of the instrument body to form another ligature.
