Interfacing media manipulation with non-ablation radiofrequency energy system and method
First Claim
1. A method for inducing a therapeutic response in living tissue while minimizing current deposition in living tissue, the method comprising:
- providing a probe to an aqueous salt ion solution of a treatment site where a therapeutic response in living tissue is desired wherein the probe includes an active electrode and a return electrode separated by an insulator and wherein the living tissue is separated from the active electrode by a plenum housing the active electrode;
immersing of at least the portion of the probe and plenum including the active electrode and the return electrode in the aqueous salt ion solution;
positioning the plenum housing the active electrode in close proximity to the treatment site, the active electrode and return electrode being immersed in the aqueous salt ion solution; and
applying a high voltage potential between the electrodes to deliver an electromagnetic non-ionizing radiation to the living tissue at the treatment site to induce a therapeutic response in the living tissue.

Abstract
The effects produced by surgical devices that deploy an electrical circuit between electrodes are dependent on the nature of electrical work perform upon the conductive media in an around biologic tissues. Non-ablation radiofrequency surgical devices utilize a protective housing that provides, based upon procedure-specific needs, the ability to 1. move, manipulate, and segregate near-field effects both tangentially and perpendicularly to the tissue surface, 2. deliver far-field electromagnetic effects to tissue unencumbered by current deposition, and 3. serve as a 20 mechanical adjunct to and a selective throttling vent/plenum for energy delivery. Because the electrodes are non-tissue-contacting, this study characterizes the effects that non-ablation radiofrequency energy exerts upon interfacing media typically encountered during surgical applications. These devices create a Repetitive Molecular Energy Conversion Loop for surgical work; and, non-ionizing electromagnetic forces are deployed in strength levels that can produce thermal and non-thermal biologic tissue effects. A differential between current density dispersion and electromagnetic field strength is exploited to allow normal tissue healing responses to the near-field effects of tissue modification and preconditioning while permitting far-field effects, which are useful for inducing therapeutic biologic responses, to manifest in treated tissues that have been protected from electrical current generated collateral damage.
