Title
(EN) DEVICE FOR THE TREATMENT OF ATRIAL ARRHYTHMIA
(FR) PROCEDE POUR LE TRAITEMENT DE L'ARYTHMIE AURICULAIRE
Abstract
(EN)
A process for the treatment of atrial arrhythmia by use of ablation procedures comprising circumferential ablation of vessels, particularly pulmonary veins, associated with the left atrium of the heart. Also medical devices for such process including a pair of balloons secured to a catheter with one balloon located within the other balloon and an ablation catheter located within one of the balloons, which devices are used for the formation of a circumferential ablation lesion in the pulmonary vein.
(FR)
L'invention concerne un procédé pour le traitement de l'arythmie auriculaire au moyen de procédures d'ablation comprenant l'ablation circonférentielle de vaisseaux, en particulier de veines pulmonaires, associés à l'oreillette gauche du coeur. L'invention concerne en outre des dispositifs médicaux destinés à un tel procédé comprenant, l'un à l'intérieur de l'autre, deux ballonnets fixés à un cathéter, et un cathéter d'ablation à l'intérieur d'un des ballonnets. Lesdits dispositifs servent à la formation d'une lésion par ablation circonférentielle dans la veine pulmonaire.
