Abstract

L'invention concerne une électrode active destinée au traitement de tumeurs ou autres affections utilisant une hyperthermie induite par fréquence radio. L'électrode active (11) est réalisée dans un matériau tel que de la céramique ou du graphite conducteur (12), placé dans une extrémité distale d'un corps cathéter. L'électrode est connectée à un générateur de fréquence radio et a au moins un conduit longitudinal continuant dans un conduit correspondant dans le corps du cathéter pour permettre le passage d'un fil-guide ou arbre.
