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.
Claims36
An electrosurgical method of treating ulcer tissue, comprising:
- positioning an active electrode proximate to the ulcer tissue, the active electrode disposed on a distal end of a shaft;
- and
- applying a high-frequency voltage potential difference across the active electrode and a return electrode sufficient to form a plasma at the active electrode, whereby the plasma alters the expression of inflammatory response in the ulcer tissue and promotes the healing of the ulcer tissue.
