Abstract

Un système d'ablation comprend un dispositif d'électrode d'ablation qui peut être reliée de manière fonctionnelle aux sources d'énergie électrochirurgicale et au fluide de refroidissement. Le dispositif d'électrode comprend un moyeu définissant un logement à l'intérieur; au moins une aiguille d'ablation conductrice d'électricité se prolongeant du moyeu, l'aiguille d'ablation comprenant une portion d'extrémité distale configurée pour pénétrer dans le tissu, ladite portion d'extrémité distale étant conductrice d'électricité et de chaleur pour établir une communication électrique et thermique avec les tissus; un dissipateur de chaleur relié de manière fonctionnelle à l'aiguille d'ablation, le dissipateur de chaleur étant relié à l'aiguille d'ablation pour extraire l'énergie d'au moins sa portion d'extrémité distale, le dissipateur de chaleur comportant une extrémité proximale s'étendant dans le logement du moyeu et un conduit relié de manière fluidique au moyeu pour distribuer le fluide dans son logement à partir de la source de fluide, où le fluide extrait l'énergie de l'extrémité proximale du dissipateur de chaleur.
