Abstract
A method and an apparatus for facilitating the healing of soft tissue wounds. The method includes the steps of selecting an area of tissue that is wounded, and applying therapeutic microcurrent excursions ranging from 100 to 1,000 microamperes and having a frequency of 10 to 50 hertz to the selected area of tissue. The apparatus includes a bandage containing circuitry for generating the therapeutic microcurrent excursions and a first and a second electrode coupled to the circuitry. A housing holds said first and second electrodes apart and adjacent to said selected area of tissue when the apparatus is placed over the selected area of tissue. During operation of the apparatus, an electric circuit is completed as microcurrent excursions propagate from the first electrode across the selected tissue wound to the second electrode.
