First Claim
Patent Images
1. An electrosurgical method of treating ulcer tissue, comprising:
- positioning an active electrode in close proximity to the ulcer tissue, the active electrode disposed on a distal end of a shaft; and
applying a high-frequency voltage between the active electrode and a return electrode;
modifying the ulcer tissue, wherein modifying the ulcer tissue comprises;
removing at least first and second ulcer tissue portions, wherein the at least first ulcer tissue portion is debrided and the at least second ulcer tissue portion is perforated;
inducing blood flow from an underlying tissue adjacent the at least second ulcer tissue portion for restoring blood flow to and in the presence of the ulcer tissue; and
passing a minimal current flow through the ulcer tissue;
wherein modifying the ulcer tissue results in stimulating healthy tissue growth and promoting the healing of the ulcer tissue.

Abstract
An electrosurgical method for treating foot ulcer, including diabetic foot ulcer, comprising: positioning an active electrode in close proximity to the ulcer, the active electrode being disposed on a distal end of an electrosurgical shaft; applying a high-frequency voltage potential difference across the active electrode and a return electrode in the presence of an electrically conductive fluid, the voltage potential being sufficient to generate plasma at the active electrode; and stimulating the ulcer with the active electrode to increase blood flow, remove unhealthy tissue and induce the body'"'"'s natural healing response.

20. An electrosurgical method of treating ulcer tissue, comprising:
-
positioning an active electrode in close proximity to the ulcer tissue, the active electrode disposed on a distal end of a shaft; and applying a high-frequency voltage between the active electrode and a return electrode; modifying the ulcer tissue, wherein modifying the ulcer tissue comprises the steps of; perforating at least a portion of the ulcer tissue with the active electrode wherein perforating comprises removing the at least a portion of the ulcer tissue; inducing blood flow from an underlying tissue, wherein the induced blood flow restores blood flow to and in the presence of the ulcer tissue; and passing a minimal current flow through the ulcer tissue; wherein modifying the ulcer tissue results in stimulating healthy tissue growth promotes the healing of the ulcer tissue.

21. An electrosurgical method of treating ulcer tissue, comprising:
-
positioning an active electrode in close proximity to the ulcer tissue, the active electrode disposed on a distal end of a shaft; and applying a high-frequency voltage between the active electrode and a return electrode; modifying the ulcer tissue, wherein modifying the ulcer tissue comprises the steps of; removing at least first and second ulcer tissue portions with the high-frequency voltage at the active electrode, wherein the removing comprises debriding the at least first ulcer portion and perforating the at least second ulcer tissue portion; inducing a blood flow from an underlying tissue, wherein inducing blood flow and restores blood flow to and in the presence of the ulcer tissue; and passing a minimal current flow through the ulcer tissue; wherein modifying the ulcer tissue results in stimulating healthy tissue growth to promotes the healing of the ulcer tissue.
