Abstract: A surgical clamp and method of use of same. The surgical clamp has (a) a shaft with proximal and distal ends; (b) two opposing jaw members with proximal ends, distal ends, cooperating faces, and lateral faces, the jaw members hingedly attached at their proximal ends to the distal end of the shaft, the jaw members adapted to clamp tissue placed between the cooperating faces; (c) a cylinder slidably disposed around the shaft, the cylinder adapted to urge the opposing jaws together when is axially displaced toward the distal end of the shaft and over the lateral faces of the jaw members; and (d) the shaft the jaw members and the cylinder is formed of radiolucent material.

Abstract: A novel subcutaneous tunnelling instrument and method for placing a subcutaneous catheter between two remote incisions in a patient, comprising making a subcutaneous tunnel by pushing a rod having an elongated bullet-shaped tip removably threaded upon male threads disposed at the distal end thereof into one incision and subcutaneously tunnelling to and out through the second incision, removing the bullet-shaped tip from the distal end of the rod, sliding the open end of a catheter over the male threads disposed at the distal end of the rod until the catheter abuts the rod, thereafter pulling the distal end of the rod back into the second incision and through the subcutaneous tunnel to and through the first incision, and thereafter removing the open end of the catheter from the male threads at the distal end of the rod.

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.
