Title
(EN) DEVICE AND METHOD FOR TREATING TISSUE
(FR) DISPOSITIF ET PROCÉDÉ DE TRAITEMENT DE TISSU
Abstract
(EN)
A device and method for treating tissue. Two or more pairs of needle electrodes are spaced about a zone and each pair of needle electrodes includes a first needle electrode on one side of the zone and a second needle electrode on an opposite side of the zone. An energy source for each pair of needle electrodes is configured to induce current from the first needle electrode of the pair to only the second needle electrode of the pair through the interior of the zone to increase the total current density and temperature in the interior of the zone.
(FR)
La présente invention concerne un dispositif et un procédé de traitement de tissu. Au moins deux paires d'électrodes aiguilles sont espacées autour d'une zone et chaque paire d'électrodes aiguilles comprend une première électrode aiguille sur un côté de la zone et une seconde électrode aiguille sur un côté opposé de la zone. Pour chaque paire électrodes aiguilles, une source d'énergie est conçue pour induire un courant de la première électrode aiguille de la paire à seulement la seconde électrode aiguille de la paire à travers l'intérieur de la zone pour augmenter la densité de courant totale et la température à l'intérieur de la zone.
