Abstract

L'invention concerne un procédé de traitement de tissus du corps contenant des cellules cancéreuses ou des tumeurs non malignes par ablation RF seule ou combinée avec une chimiothérapie systémique ou localisée. Ledit procédé consiste à introduire un stylet comprenant une surface d'électrode sur laquelle se déplace longitudinalement un manchon à proximité des tissus du corps à traiter, à écarter le manchon d'une partie de la surface de l'électrode, à envoyer une énergie RF suffisante sur la surface de l'électrode pour porter le tissu à une température supérieure à 45 °C pendant un certain temps et réduire la masse tissulaire à proximité de l'électrode. L'énergie RF envoyée dans la surface de l'électrode est suffisante pour produire une capsule desséchée faisant barrage à la diffusion de fluide autour du tissu à traiter. Le stylet peut comprendre un tube creux dans lequel des orifices de distribution de fluide sont prévus, le fluide étant envoyé dans le tissu par un ou plusieurs orifices. Ledit fluide peut être salin ou chimiothérapeutique tel qu'un liquide ou un gaz contenant un agent cytotoxique. Celui-ci peut être administré de diverses manières: il peut être envoyé dans le corps à travers un orifice de distribution avant, pendant et/ou après que l'énergie RF a été envoyée sur la surface de l'électrode. Le fluide est, de préférence, introduit une fois la capsule de barrage formée. Le dispositif comporte des électrodes à noyau creux et à extrémité distale tranchante fermée. L'électrode présente une pluralité d'orifices de distribution conçus pour la distribution d'agents de traitement fluides dans le tissu à traiter.
