Abstract

La sonde médicale décrite comporte un cathéter (2) pourvu d'un extrémité commande et d'une extrémité sonde. Cette dernière comprend une gaine (6) de guidage du stylet possédant au moins un orifice et un moyen de guidage permettant de faire passer un stylet souple (8) à travers au moins un orifice et à travers les tissus intermédiaires pour parvenir aux tissus ciblés. Un stylet (8) est positionné dans au moins l'un desdits moyens de guidage, ce stylet comprenant un manchon (30) non conducteur présentant un canal (50) d'électrode H.F. et éventuellement un canal (60) d'amenée de fluide ainsi qu'un canal (58) pour détecteur de température. Au moins une partie d'une surface opposée du canal d'électrode et cette dernière (32) peuvent être espacées pour définir un passage d'amenée de liquide pour l'apport d'un médicament liquide. L'électrode H.F. enserrée au sein du manchon non conducteur présente une longueur distale possédant éventuellement au moins un rainurage (70) de concentration de courant et une pointe distale façonnée pour concentrer la conduction localisée sur son extrémité.
