Abstract
A method and apparatus for dehydrating, electro-oxidizing, or electro-reducing a target tissue is described. The apparatus utilizes an electrochemical probe or other device to deliver one or more beneficial agents into the target tissue. Water from the target tissue provides a precursor that may be split by electrolysis to generate the beneficial agent. Alternatively, water is provided from an external source to generate the beneficial agent. The beneficial agent facilitates in situ oxidation and/or reduction of a material within the tissue. One type of beneficial agent is ozone.
