Abstract: An electrosurgical system and method for ablating, resecting, or cutting body structures, with minimal or no damage to tissue adjacent to the treatment site. The system includes an electrosurgical probe having a shaft with a shaft distal end bifurcated to provide first and second arms. First and second electrode supports are disposed on the first and second arms, respectively. At least one active electrode, in the form of a loop or partial loop, is arranged between the first and second electrode supports. A return electrode, also in the form of a loop or partial loop, is arranged between the first and second electrode supports distal to the active electrode. The active and return electrodes are configured to promote substantially high electric field intensities and associated high current densities between the active portion and the target site when a high frequency voltage is applied to the electrodes.
