A single operator exchange biliary catheter having a common distal lumen. The biliary catheter includes an elongate shaft having a proximal portion defining an ancillary lumen and a distal portion defining a common guidewire and ancillary lumen. The common distal lumen reduces the profile of the distal portion of the shaft. The elongate shaft also includes a proximal guidewire port disposed between the proximal end of the shaft and the distal end of the shaft to facilitate single operator use. A seal may be disposed adjacent the proximal guidewire port to thereby seal the port. Preferably, the shaft includes a single lumen distal portion and a bi-lumen proximal portion. The single lumen distal portion of the shaft may be curved and may include a tapered or spherically shaped distal tip.
A biliary catheter for use in combination with a guidewire and an endoscope, comprising an elongate shaft having a proximal end, a distal end and a lumen extending therethrough, the lumen having a proximal portion and a distal portion, the proximal portion defining an ancillary lumen, the distal portion defining a common guidewire and ancillary lumen, the elongate shaft also having a distal guidewire port disposed adjacent the distal end of the shaft, wherein the distal guidewire port is open to allow flow therethrough when a guidewire is disposed therein, and a proximal guidewire port disposed between the proximal end of the shaft and the distal guidewire port, wherein a seal is disposed adjacent the proximal guidewire port, wherein the seal provides a fluid seal about the guidewire disposed therein, thereby sealing the proximal guidewire port.
