Abstract
A cholangiogram catheter for use in a laparoscopic cholecystectomy has a rigid tubular outer sheath dimensioned to slide within an associated trocar sleeve, and an outer tubular catheter is slidably seated within the outer sheath with its distal end portion formed into a 90.degree. bend and is resiliently deflectable for withdrawal into the sheath. A flexible inner tubular catheter is readily slidable within the outer catheter and is longitudinally dimensioned to extend outwardly of both ends of the outer catheter. The distal end of the inner catheter has a closed tip and a discharge aperture along its side adjacent the tip. Luer connectors are attached to the proximal ends of the several elements.
