Abstract
L'invention se rapporte au domaine des équipements médicaux pour traiter des patients souffrant d'une obstruction des uretères. Ce complexe de dérivation néphro-vésiculaire comprend un connecteur, un cathéter de néphrostomie à installer dans le pelvis rénal, un cathéter de cystostomie que l'on installe dans la vessie, un port pour l'administration de médicaments, le prélèvement d'échantillons et le lavage, un tube en silicone pour relier le connecteur au port, des raccords de connexion pour fixer les extrémités proximales des cathéter et du tube aux évacuations du connecteur. Le connecteur permet de connecter hydrauliquement le port et les cathéters. Dans l'ouverture longitudinale du cathéter de néphrostomie se trouve un fil traversant des ouvertures transversales formées sur son extrémité distale recourbée. L'extrémité proximale du cathéter de néphrostomie comporte deux évacuations. Les extrémités du fil traversent une membrane sur le couvercle disposé sur une des évacuations, et sont fixées par un plomb. L'extrémité proximale du cathéter de néphrostomie peut être taillée. On assure ainsi une dérivation sûre en réduisant au minimum les complications grâce à une diminution du risque d'inflammations, une commodité d'ajustement de la position du cathéter de néphrostomie dans le bassinet du rein et une meilleure fixation des cathéters de néphrostomie et de cystostomie dans le corps du patient.
