Abstract
Cette invention se rapporte à un procédé permettant d'avoir accès par électrochirurgie à l'arbre biliaire et à visualiser un de ses conduits (40) à l'aide d'un cathéter (10) comportant au moins un premier lumen (32) et un second lumen (34). Dans le premier lumen (32) est placé un bistouri à aiguille (206) qui peut être déplacé entre une position déployée et une position rentrée et qui communique avec une source de courant électrique. Le procédé consiste à: (a) insérer le cathéter (10) dans un endoscope (36) et dans le duodénum (38) du patient à proximité de l'entrée menant au canal cholédoque (40); (b) déployer le bistouri à aiguille (206); (c) manipuler le bistouri à aiguille (206) et y appliquer un courant afin d'inciser le tissu proche de l'entrée menant au canal cholédoque (40); (d) dégager le bistouri à aiguille (206) et l'amener en position rentrée; (e) faire avancer le cathéter (10) dans le canal cholédoque jusqu'à un endroit désiré dans le canal (40); et (f) injecter un milieu de contraste dans le second lumen (34) du cathéter (10) afin de visualiser le canal cholédoque (40) à l'aide de ce milieu de contraste tout en laissant le bistouri à aiguille (206) dans le premier lumen (32) du cathéter.
