A system is provided for treating tumor tissue sites of a patient. At least first and second mono-polar electrodes are configured to be introduced at or near the tumor tissue site of the patient. A voltage pulse generator is coupled to the first and second mono-polar electrodes. The voltage pulse generator is configured to apply sufficient electrical pulses between the first and second mono-polar electrodes to induce electroporation of cells in the tumor tissue site, to create necrosis of cells of the tumor tissue site, but insufficient to create a thermal damaging effect to a majority of the tumor tissue site.

L'invention concerne un système destiné à traiter des sites d'un tissu cancéreux d'un patient. Au moins une première et une seconde électrodes monopolaires sont configurées pour être introduites dans ou à proximité du site du tissu cancéreux du patient. Un générateur d'impulsions électriques est couplé aux électrodes monopolaires. Le générateur d'impulsions électriques est configuré pour appliquer entre la première et la seconde électrodes monopolaires des impulsions électriques suffisantes pour déclencher dans le site du tissu cancéreux une électroporation de cellules pouvant provoquer la nécrose de cellules du site du tissu cancéreux, mais insuffisantes pour créer un effet thermique destructeur sur la majeure partie du site du tissu cancéreux.
