Abstract

La présente invention concerne un système cathéter comprenant un ballon à introduire de manière transdermique et transluminale dans un corps pour faire obstruction à l’organe creux d’un corps ; il est parfois nécessaire de fournir un adaptateur détachable pour gonfler et dégonfler le ballon. Il est également nécessaire de joindre/détacher l’adaptateur tout en maintenant le ballon à l’état gonflé. Les adaptateurs existants présentent la faiblesse qu’une procédure compliquée est nécessaire de sorte que le délai d’obstruction est prolongé. Ce problème peut être résolu en fournissant un système cathéter comprenant un ballon, un membre tubulaire à lumière de gonflement, le corps principal du cathéter comprenant un joint d’étanchéité aux liquides et un adaptateur à joindre au corps principal du cathéter, caractérisé en ce que le joint est ouvert en insérant le corps principal du cathéter et le joint d’étanchéité dans l’adaptateur et fermé en tirant le joint de l’adaptateur, ce qui épargne les problèmes de la procédure.
