Abstract

An electrosurgical device includes a high dielectric material and at least one conductor arranged relative to the high dielectric material such that, in use, the high dielectric material is disposed between the conductor and target tissue. A second conductor is arranged relative to the high dielectric material such that, in use, the high dielectric material is disposed between the second conductor and target tissue. Each conductor includes a plurality of conductive fingers interleaved, e.g. in a comb-like fashion or as concentric circles. A method for performing electrosurgery includes delivering energy to a target tissue through a high dielectric material. The electrosurgery includes, e.g., ablation, coagulation, or the treatment of skin lesions.
