VARIABLE FREQUENCY EXCITATION PLASMA DEVICE FOR THERMAL AND NON-THERMAL TISSUE EFFECTS

摘要

PROBLEM TO BE SOLVED: To provide a plasma device and process for surface processing and tissue treatment.SOLUTION: A plasma system 10 includes: a plasma instrument 12 having an elongated body 120 defining a lumen therethrough and a first and a second electrode; an ionizable media source 16 in fluid communication with the lumen and configured to supply ionizable media to the lumen; and a variable frequency energy source configured to supply the first and second electrodes with energy sufficient to ignite ionizable media supplied by the ionizable media source to generate a plasma influent, where a frequency of the energy is adjustable to modify at least one property of a plasma effluent.SELECTED DRAWING: Figure 1
