Title (EN) METHOD AND APPARATUS FOR PRECISELY CONTROLLING THE SIZE AND SHAPE OF RADIOFREQUENCY ABLATIONS
(FR) PROCÉDÉ ET APPAREIL DE MAÎTRISE DE LA DIMENSION ET DE LA FORME PRÉCISES D'ABLATIONS PAR RADIOFRÉQUENCE
Abstract: front page image
(EN)Various embodiments of multielectrode radiofrequency (RF) ablation probes are described herein that disclose methods and apparatus for improved control and predictability of the size and shape of RF thermal electrocoagulations. The features of the invention include the ability to make irregularly shaped ablations in order to conform to irregularly shaped target tissue volumes, and to make very large ablations without the requirement for electrode cooling.
(FR)Selon différents modes de réalisation, la présente invention concerne des sondes d'ablation par radiofréquence (RF) à plusieurs électrodes, ainsi que des procédés et un appareil qui permettent de mieux maîtriser et de mieux prédire la dimension et la forme d'électrocoagulations thermiques RF. Les caractéristiques de l'invention comprennent la capacité d'effectuer des ablations de forme irrégulière de façon à se conformer à des volumes de tissus cibles de forme irrégulière, et d'effectuer des ablations très larges sans nécessiter de refroidissement d'électrode.
