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.

Ce cathéter des voies biliaires comprend une lumière distale commune, un axe de forme allongée présentant une portion proximale définissant une lumière annexe, et une portion distale définissant un guide métallique commun et une lumière annexe. La lumière distale commune permet de réduire le profil de la portion distale de l'axe, lequel comprend également un orifice de guide métallique proximal, situé entre l'extrémité proximale et l'extrémité distale de l'axe, de manière à faciliter l'utilisation du cathéter par un seul opérateur. On peut placer un scellement au voisinage de l'orifice du guide métallique proximal, de manière à sceller l'orifice. De préférence, l'axe comporte une portion distale à une seule lumière et une portion proximale à deux lumières. La portion à une seule lumière de l'axe peut être courbe et peut comprendre un embout distal de forme conique ou sphérique.
