The invention relates to a device (1), especially a tube or a catheter, for at least partially introducing into a body passage, said device comprising a long outer envelope body (10), a long inner body (11) that is partially peripherally surrounded by the envelope body (10), and a device (12) by which means the possibility of a relative movement between the envelope body (10) and the inner body (11) is enabled or impeded in a targeted, controllable manner. According to the invention, the control device (12) is formed by the arrangement and embodiment of the envelope body (10) and the inner body (11) and comprises no additional mechanical means in the annular intermediate region (13) between said two bodies (10, 11). Preferably, the control device is embodied in such a way that it acts on the friction between the envelope body and the inner body (10, 11).
L'invention concerne un dispositif (1), notamment un tube ou un cathéter, destiné à être introduit au moins partiellement dans un conduit du corps, comportant au moins une gaine externe (10) allongée, un élément intérieur (11) allongé, entouré au moins partiellement sur sa périphérie par la gaine (10), et une unité (12) qui, de manière ciblée, autorise ou au moins rend difficile un mouvement relatif entre la gaine (10) et l'élément intérieur (11). Selon l'invention, l'unité de commande (12) est créée par l'agencement et la conception de la gaine (10) et du corps intérieur (11) et ne présente aucun moyen mécanique supplémentaire dans l'espace intermédiaire (13) annulaire entre la gaine (10) et le corps intérieur (11). De préférence, l'unité de commande agit sur la friction entre la gaine (10) et le corps intérieur (11).
