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, at least a portion of which comprises necrotic tissue;

    delivering an electrically conductive fluid proximate the active electrode; and

    applying a high frequency voltage between the active electrode and a return electrode in the presence of the electrically conductive fluid sufficient to generate an ionized vapor layer at the active electrode;

    removing at least a portion of the necrotic tissue in a substantially non-thermal manner by application of the ionized vapor layer to the chronic wound tissue, wherein the step of removing further comprises;

    sterilizing at least a portion of the wound bed while applying the ionized vapor layer; and

    preparing a uniform tissue surface more conducive to wound healing.
