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.

Claims (5)

1. A device for applying energy to a treatment site on living tissue during electrosurgery of a subject comprising:

an active electrode electrically coupled to an electric current power supply;

a lumen;

a non-conductive plenum disposed on a distal end of said lumen, said plenum at least substantially surrounding said active electrode; and

at least two elongated openings extending along the sides of said plenum wherein a primary axis of the elongation is at least substantially parallel with a primary axis of said lumen wherein said active electrode and said elongated openings in said plenum provide a current density that is dispersed into an interfacing media via said elongated openings in said plenum for indirect treatment of living tissue by preventing direct contact of said active electrode with the living tissue at the treatment site.
