Title
(EN) MAGNETICALLY GUIDED CATHETERS
(FR) CATHÉTERS À GUIDAGE MAGNÉTIQUE
Abstract
(EN)
A magnetically-guided catheter 100 includes a tip positioning magnet in the distal electrode assembly configured to interact with externally applied magnetic fields for magnetically-guided movement. A magnetically-guided mapping catheter 100 includes an electrically-conductive capsule in the form of a casing 146 that includes a distal ablation surface and isolates the positioning magnet from bio-fluids to prevent corrosion. An open irrigation ablation catheter includes an isolated manifold that isolates the positioning magnet from contact with irrigation fluid to prevent corrosion.
(FR)
Cette invention concerne un cathéter à guidage magnétique (100) comprenant un aimant de positionnement de la pointe situé dans l'ensemble électrode distale configuré pour interagir avec des champs magnétiques appliqués en externe et dirigeant le mouvement dudit cathéter. Un cathéter de cartographie à guidage magnétique (100) comprend une capsule électroconductrice se présentant sous forme d'un étui (146) qui comporte une face d'ablation distale et isole l'aimant de positionnement des liquides biologiques pour éviter toute corrosion. Un cathéter ouvert d'ablation par irrigation comprend un collecteur isolé qui isole l'aimant de positionnement du contact avec le liquide d'irrigation pour éviter toute corrosion.
