Title (EN) STEERABLE CATHETER WITH PORTIONS OF DIFFERENT STIFFNESS
(FR) CATHÉTER ORIENTABLE À PARTIES DE RIGIDITÉ DIFFÉRENTE
Abstract:
(EN) A steerable catheter (10) comprises portions (100, 105) of different stiffness, having a proximal end (11), a distal end, a lumen extending there between, at least one magnet (20) at the proximal end (11), at least a magnetic field to influence the proximal end (11), wherein portions (100, 105) of the steerable catheter (10) can be of different stiffness. The portions (100, 105) of different stiffness are in fact portions of variable stiffness based on a phase change between a liquid phase and a solid phase of a liquid-solid material in a at least partly double walled catheter providing a cavity for this liquid-solid material and having additional control elements configured to influence the phase of the liquid-solid material.
(FR) L’invention concerne un cathéter orientable comprenant des parties (100, 105) de rigidité différente, ayant une extrémité proximale (11), une extrémité distale, une lumière s'étendant entre celles-ci, au moins un aimant (20) au niveau de l'extrémité proximale (11), au moins un champ magnétique pour influencer l'extrémité proximale (11), des parties (100, 105) du cathéter orientable (10) pouvant être de rigidité différente. Les parties (100, 105) de rigidité différente sont en effet des parties de rigidité variable sur la base d'un changement de phase entre une phase liquide et une phase solide d'un matériau liquide-solide dans un cathéter au moins partiellement à double paroi fournissant une cavité pour ce matériau liquide-solide et ayant des éléments de commande supplémentaires configurés pour influencer la phase du matériau liquide-solide.
