An indwelling urinary catheter for transurethral introduction into a urinary bladder is shown and described herein. The catheter includes a flexible catheter shaft having a wall, a filling channel is integrated into the wall, and a thin foil balloon element having a film-like structure. The balloon element when positioned in the bladder is adapted to contact internal urinary bladder structures over at least about 30 percent of a balloon element surface area. The seal is greater than seals of equivalent balloon structures.

La présente invention concerne un cathéter urinaire à demeure pour une introduction par l'urètre dans une vessie. Le cathéter comprend un arbre de cathéter souple présentant une paroi, un canal de remplissage étant intégré à la paroi, et un ballonnet en feuille mince ayant une structure du type film. Ledit ballonnet, lorsqu'il est positionné dans la vessie, est conçu pour entrer en contact avec les structures internes de la vessie sur au moins environ 30 pour cent de la surface spécifique dudit ballonnet. L'étanchéité est supérieure à celle des structures à ballonnet équivalentes.
