Abstract

L'invention concerne une électrode d'ablation radiofréquence destinée au traitement de tumeurs, qui comprend une pointe d'aiguille (11), des sous-aiguilles (12), une tige d'aiguille (14) et un manche (18). Des couplages thermiques (120) sont fixés à la pointe des sous-aiguilles (12) et des trains intermédiaires (26, 27) sont logés à l'intérieur du manche (18) pour enrouler les sous-aiguilles (12). La pointe des sous-aiguilles (12) est conductrice, et les autres parties des sous-aiguilles (12), la pointe d'aiguille (11) et la tige d'aiguille (14) sont revêtues de couches isolantes. Les sous-aiguilles peuvent être complètement déployées pour former un ellipsoïde dont le diamètre le plus long est d'au moins 5 cm. La longueur du manche peut être inférieure à 10 cm.
