Claim One:
1. A method of percutaneous treatment of a prostate lesion using radio frequency, comprising: with an imaging device, acquiring an image of a patient's prostate; identifying within the prostate at least one location to be treated; selecting a bipolar electrode assembly for radio frequency treatment, the assembly comprising an outer helical electrode and at least one inner electrode arranged concentric with the outer electrode; representing a planned target region on the image of the prostate, the planned target region corresponding to a target position of at least an active part of the outer helical electrode, wherein the planned target region is placed such that it encloses the location to be treated; positioning the bipolar electrode assembly in proximity of the patient's perineum and in alignment with the planned target region's position; inserting at least the outer helical electrode of the bipolar electrode assembly percutaneously into the prostate; and capturing the inserted outer helical electrode with the imaging device and representing the inserted, captured outer helical electrode on the image of the prostate together with the planned target region so as to obtain a direct verification of the degree of match between the position of the outer electrode and the planned target region.
