DEVICES AND METHODS FOR TREATING SKIN TISSUE USING COLD PLASMA

Abstract: disclosed herein is a system for treating skin and/or nails with cold plasma. the system includes a discharge device, which includes a handle and an applicator mounted thereon, and control infrastructure, which includes a waveform generator. the applicator includes an elongated tube housing therein a cathode. the handle includes a flyback amplifier. the waveform generator is configured to induce the flyback amplifier to establish a voltage at the cathode. the voltage produced by the flyback amplifier is configured to generate a self-sustaining townsend avalanche when a distal end of the tube is positioned sufficiently near a target site on a skin surface or a nail of a subject, such that a cold plasma discharge is produced and directed at the target site and having an average power between about 0.1 �w and about 10 �w, so that the target site is not heated.
