1. An apparatus for epidermal tissue ablation comprising:

  • a shaft having proximal and distal end portions with an active electrode terminal disposed on the distal end portion;

    a return electrode disposed on the shaft;

    a fluid delivery element defining a fluid path in electrical contact with the return electrode and the active electrode terminal, the fluid path having an inlet adapted to be fluidly coupled to an electrically conducting fluid supply for directing fluid along the fluid path to generate a current flow path between the return electrode and the electrode terminal; and

    a high frequency power supply power coupled to the return electrode and the active electrode for applying a voltage difference there-between, the voltage difference being sufficient to volumetrically remove a portion of the epidermal tissue.
