Title (EN) ATRIAL FIBRILLATION RF TREATMENT DEVICE AND METHOD
(FR) DISPOSITIF ET METHODE DE TRAITEMENT RF DE FIBRILLATION AURICULAIRE
Abstract:
(EN) A radiofrequency treatment device of the present invention includes one or two radio frequency electrode holders (42) each having multiple electrodes (44) arranged to create a transmural lesion through tissue. The treatment device is placed with one holder (42) on the endocardial surface of the heart and the other optional holder placed on the epicardial surface of the heart to form a bipolar arrangement of equally spaced parallel tissue penetrating electrodes. The invention creates a transmural lesion in heart tissue to treat atrial fibrillation by blocking passage of abnormal electrical currents through the heart tissue. The devices may also be used to apply other types of energy, including cryo, ultrasound, microwave, heat, or other electrical means of providing an interruption in abnormal electrical circuits.
(FR) L'invention concerne un dispositif de traitement RF comprenant un ou deux supports d'électrodes radiofréquences comportant chacun une pluralité d'électrodes conçues pour former une lésion transmurale à travers le tissu. Ce dispositif de traitement est disposé avec un support placé sur la surface endocardique du coeur, l'autre support facultatif étant placé sur la surface épicardique du coeur, de manière à former un agencement bipolaire d'électrodes de pénétration tissulaire parallèles et équidistantes. L'invention permet de former une lésion transmurale dans le tissu cardiaque en vue de traiter la fibrillation auriculaire par blocage du passage des courants électriques anormaux dans le coeur. Elle permet également de former des lésions transmurales continues dans le tissu cardiaque et d'autres tissus et organes corporels en vue de traiter d'autres états pathologiques. Ces dispositifs peuvent également servir à appliquer d'autres types d'énergie, tels que la cryoénergie, les ultrasons, les micro-ondes et la chaleur, ou d'autres moyens électriques destinés à provoquer une interruption dans les circuits électriques anormaux.
