Abstract

A method and apparatus for destroying blood borne pathogens is disclosed which utilizes a low intensity direct current to generate positive particles from various metals which destroy viral pathogens. A first electrode comprised of a metal such as silver is inserted into a patient'"'"'s venous system. Then, a second electrode is placed on the patient'"'"'s exterior in the vicinity of the first electrode. A low intensity direct current is applied to the first metal electrode which releases silver cations to be bonded to the virus, resulting in the denaturing of the virus. The first electrode is placed in the venous system of the infected patient via a catheter.
