1. A method of applying energy to tissue, said method comprising:
engaging a dielectric wall against the tissue, the dielectric wall defining a chamber therein;
delivering an electrically non-conductive gas into the chamber;
applying a voltage between a first electrode and a second electrode to initiate ionization of the gas into a plasma completely contained within the chamber and separated from the tissue by the dielectric wall; and
capacitively coupling the plasma across the dielectric wall and into the tissue.
