<p>A device for the thermal ablation (TA) of tumors by means of electromagnetic energy at high frequency comprising a thin hollow element (1), one or more electrodes (1, 8) connected to an electromagnetic energy generator at high frequency, e.g. radiofrequencies or microwaves, said element (1) being suitable for injecting a substance (4) into a tumoral mass, through one or more openings (3) provided in proximity of the tip (2) of the same hollow element (1). The substance (4) is biocompatible, dehydrates or boils at higher temperatures than the boiling temperature of the tissue liquids, has a higher viscosity than that of the blood and has an electrical conductivity comprised between one tenth and one hundred times that of the tissue liquids. The invention also relates to a method using the above-mentioned device for the thermal ablation.</p> |
