ABSTRACT:
A improved biliary catheter is disclosed. The catheter comprises a tube constructed from a polyurethane or nylon having a durometer of about 60D and coated with a hydrophilic coating to provide lubricity, kink resistance and suppleness. The tube has substantially cylindrical sidewalls and a proximal end for connection to a source of contrast medium and a distal end for entry into the common biliary duct of a patient. The tube contains a first crescent-shaped lumen channel extending between the proximal and the distal end, the first lumen channel transporting the contrast medium from the source of contrast medium to the biliary duct; and a second circular lumen channel extending between the proximal end and said distal end for facilitating the insertion and threading of a spring wire guide into the dual-lumen biliary catheter.
