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.
