Abstract

Cette invention a trait à un cathéter de longueur et de forme variables, utilisable à des fins médicales ou autres, exigeant l'introduction de différents dispositifs dans un milieu susceptible d'être lésé par un intervention mécanique et/ou dépourvu de parois de confinement en forme de puits. On obtient le résultat désiré en effectuant une rotation de la section terminale d'un tube souple de manière que la partie extérieure tourne de manière à se placer de façon concentrique par rapport au tube intérieur initial. On provoque un durcissement immédiatement après le point de transition, soit en congelant le liquide que renferme le tube, soit en faisant le vide dans des canaux creux remplis de fines particules, soit en gonflant des enroulements toroïdaux que renferme le tube, soit en déployant des anneaux d'éléments solides, soit encore en faisant s'engrener les éléments de profil que contiennent les parois du tube.
