ABSTRACT:
A tool and method for transcystic duct operative cholangiography. A clip having a pair of spring biased jaws has an aperture formed on the jaws. The clip is positioned around the cystic duct and a catheter is extended through the aperture. A needle nose shaped clamp is releasably engageable with the clip and forces the jaws apart to extend around the cystic duct. Release of the clamp allows a spring within the clip to force the jaws together sealing the duct and catheter together.
