This invention is related to a tissue ablation system and method that treats atrial arrhythmia by ablating a circumferential region of tissue at a location where a pulmonary vein extends from an atrium. The system includes a circumferential ablation member with an ablation element and also includes a delivery assembly for delivering the ablation member to the location. The circumferential ablation member is generally adjustable between different configurations to allow both the delivery through a delivery sheath into the atrium and the ablative coupling between the ablation element and the circumferential region of tissue.
L'invention concerne un système et procédé d'ablation tissulaire qui traite l'arythmie atriale en réalisant une ablation d'une région circonférentielle de tissu à un emplacement, où une veine pulmonaire s'étend de l'atrium. Le système comprend un élément d'ablation circonférentiel doté d'un composant d'ablation, et un dispositif d'acheminement servant à amener l'élément d'ablation audit emplacement. Ledit élément d'ablation circonférentiel peut généralement être ajusté selon différentes dispositions pour permettre à la fois l'acheminement dans l'atrium à travers une enveloppe d'acheminement et le couplage ablatif entre le composant d'ablation et la région circonférentielle de tissu.
