DEVICE AND METHOD FOR THE THERMAL ABLATION OF TUMORS BY MEANS OF HIGH-FREQUENCY ELECTROMAGNETIC ENERGY UNDER OVERPRESSURE CONDITIONS

摘要

A device for the TA by means of high frequency comprising a thin hollow element (1) and one or more electrodes (4) being arranged in proximity of the tip (2) of said hollow element (1) and connected to an electromagnetic energy generator set at high frequencies, e.g. radiofrequencies or microwaves, wherein said hollow element (1) is tightly inserted into an expandable balloon (3). Said balloon (3) transmits to the tumoral tissues surrounding it a pressure being higher than the atmospheric one, thus increasing their boiling temperature. The invention also relates to a method for the TA by means of high frequency under overpressure conditions, employing the above-mentioned device.
