Patent

CA 2612679

Devices, systems and methods are disclosed for the mapping of electrical signals and the ablation of tissue. Embodiments include an ablation catheter that has an array of ablation elements attached to a deployable carrier assembly. The carrier assembly can be transformed from a compact, linear configuration to a helical configuration, such as to map and ablate pulmonary vein ostia.

L'invention concerne des dispositifs, des systèmes et des procédés permettant d'établir une représentation graphique des signaux électriques et de l'ablation de tissus. Certaines formes d'exécution comprennent un cathéter d'ablation qui comporte une matrice d'éléments d'ablation reliés à un ensemble de support déployable. On peut transformer l'ensemble de support d'une configuration compacte, linéaire en une configuration hélicoïdale de façon à établir une représentation graphique et à procéder à l'ablation des orifices pulmonaires.
