Title (EN) FLEXIBLE TISSUE ABLATION ELEMENTS FOR MAKING LONG LESIONS
(FR) ELEMENTS FLEXIBLES D'ABLATION TISSULAIRE DESTINES A PRATIQUER DES LESIONS LONGUES
Abstract:
(EN) This invention is devices and methods for ablating body tissue which use wire (44) wound about a support body (12) in adjacent windings to form one or more elongated electrodes. A connection couples the wire to a source of ablation energy for transmission by the elongated electrode to ablate tissue. The adjacent windings are spaced apart to impart enhanced flexibility to the elongated electrode during use.
(FR) Cette invention a trait à des dispositifs et des procédés d'ablation de tissus du corps, utilisant un fil (44) enroulé autour d'un corps de support (12) en enroulements adajacents, afin de former une ou plusieurs électrodes oblongues. Une connexion relie le fil à une source d'énergie d'ablation destinée à être transmise par l'électrode oblongue afin de procéder à l'ablation de tissus. Les enroulements adjacents sont espacés afin de conférer une flexibilité accrue à l'électrode oblongue au cours de son utilisation.
