Abstract

Un ensemble permettant d'accéder à un canal anatomique comporte un trocart (41) servant à perforer le canal anatomique. Une canule (43) incluse dans le trocart comporte une paroi cylindrique caractérisée par un diamètre externe et un diamètre interne. Un tube en élastomère (10) pourvu d'une lumière joignant l'extrémité proximale à l'extrémité distale est mobile entre, d'une part, un état normal dans lequel le tube prend un premier diamètre externe supérieur au diamètre externe de la canule, et d'autre part, un état déployé dans lequel le tube prend un second diamètre extérieur inférieur au diamètre intérieur de la canule. Un stylet (170) dont la longueur est supérieure à celle du tube dans son état normal, s'introduit dans le tube par son extrémité distale, et peut être manoeuvré de sorte qu'il passe de l'état normal à l'état déployé, le tube pouvant être ainsi inséré dans la canule, et au travers de la canule, dans le canal anatomique.
