ABSTRACT:
A clip apparatus for use in cholangiography or the like includes a clip, a catheter and a tool for applying and removing the clip from the cystic duct or the like. The clip preferably has two opposed C-shaped surfaces in jaws which can be biased together such that opposed edges touch to apply the clip or spread apart such that at least one set of opposed edges is spread to allow removal of the clip. The clip includes arms attached to the jaws which are medially bent outward at the time the clip is applied and which are compressible to rotate the jaws relative to one another about a common fulcrum to space sides of the jaws opposite the fulcrum and allow easy removal of the clip. The catheter is inserted in the cystic duct during a cholangiography procedure and held therein by the clip. The catheter is serrated on the surface thereof which engages the duct beneath the clip.
