1. An electrosurgical method of treating a chronic wound tissue comprising:

  • positioning an active electrode in proximity to the chronic wound tissue, wherein the chronic wound tissue comprises a wound bed;

    delivering an electrically conductive fluid proximate the active electrode;

    applying a high frequency voltage between the active electrode and a return electrode in the presence of the electrically conductive liquid sufficient to generate an ionized vapor layer at the active electrode and induce a discharge of energy from the vapor layer, wherein the ionized vapor layer and the discharge of energy molecularly dissociates at least a portion of the chronic wound tissue; and

    applying the energy induced from the vapor layer to a target tissue in the vicinity of the chronic wound tissue to sterilize at least a portion of the wound bed.
