Abstract
Abstract Electrical medical devices and methods are disclosed for the therapeutic treatment of cells and/or tissue in a living body. The electrical medical devices and methods of the invention are useful in the therapeutic treatment of cells and/or tissue which require a ''''bioelectrical signal'''' to artificially stimulate healing of the cells and/or tissue. The devices and methods of the invention provide for the generation of an undulating electrical signal having a wave-form whose rise time differs from its fall time which when coupled to the living body induces currents at the tissue level which currents in turn produce a voltage at the tissue level that is bipolar with the amplitude and frequency components of one polarity thereof being different from those of the opposite polarity thereof; the voltage that is bipolar effecting the bioelectrical signal at the cellular or tissue level for artificially stimulating healing of the cells and/or tissue.
