Abstract

L'invention concerne un appareil cathéter (10) pour effectuer un diagnostic et des interventions thérapeutiques sur l'arbre biliaire, constitué d'un cathéter (11) avec des canaux multiples. Un premier canal (16) est conçu pour recevoir un fil de guidage et il peut servir pour le transport de l'agent de contraste. Un second canal (17) porte un fil coupant (31) pour effectuer une sphinctérotomie. Un troisième canal (20) peut être utilisé comme canal pour gonfler un ballon disposé à l'extrémité distale. L'expansion du ballon ferme une portion de l'arbre biliaire et permet au cathéter d'évacuer les calculs biliaires par le sphincter d'Oddi dans le duodénum.
