1. A single operator exchange biliary catheter for use in combination with a guidewire and an endoscope, comprising: an elongate shaft having a proximal end, a distal end and an injection lumen extending therethrough; a guidewire lumen extending through a distal portion of the shaft between a proximal guidewire ort and a distal guidewire port, the guidewire lumen being in fluid communication with the injection lumen of the shaft, the proximal guidewire port disposed proximal of the distal end of the shaft within the distal portion of the shaft, the distal guidewire port disposed at the distal end of the shaft; a tubular member connected to the shaft, the tubular member extending proximally from the proximal guidewire port to a proximal end disposed distal of the proximal end of the shaft, the tubular member defining a guidewire lumen extension in fluid communication with the guidewire lumen and adapted to permit the guidewire to be retracted from guidewire lumen and re-inserted therein, the guidewire lumen extension being external to but parallel with the shaft; wherein the guidewire lumen extension is axially aligned with the guidewire lumen; and wherein the tubular member has a length of approximately 5 to 30 cm.
