Abstract

L'invention se rapporte à un appareil servant à amener un fluide dans l'urètre d'un patient. Le patient a une vessie. L'appareil comprend un cathéter, qui a une partie proximale et une partie distale. Un premier ballon est relié de manière opérationnelle au cathéter. Un second ballon, relié de manière opérationnelle à la partie distale du cathéter, peut être gonflé et dégonflé. Il est conçu de façon à avoir une partie gonflée qui se forme et s'allonge à mesure que le second ballon passe de l'état dégonflé à l'état gonflé. Par ailleurs, l'invention concerne un procédé pour faire parvenir un agent à une glande prostatique du patient. Le patient a une urètre et une vessie. Le procédé consiste à utiliser un cathéter qui a une partie distale, un premier ballon relié de manière opérationnelle au cathéter, un second ballon relié de manière opérationnelle à la partie distale et une partie intermédiaire située entre le premier et le second ballon. Le cathéter est inséré d'un bout à l'autre de l'urètre de façon à placer un second ballon dans la vessie. Le premier ballon est gonflé. Le second ballon est gonflé, ce qui fournit une tension axiale le long de la partie intermédiaire du cathéter, ferme hermétiquement le second ballon au niveau du col de la vessie et isole sensiblement la vessie de l'urètre.
