First Claim
1. An apparatus engagable with a power supply and manipulable by a person to apply electricity to biological tissue, comprising:
- a housing for movement proximate to the biological tissue;
an amplifier attachable to the power supply for generating a high voltage direct current;
a controller having a switch engaged with said amplifier for receiving said high voltage direct current from said amplifier and for generating a square voltage wave output from said high voltage direct current; and
an electrode assembly attached to said housing and engaged with said controller for electrical contact with the biological tissue and for transmitting said square voltage wave output to the biological tissue without further amplification of said square voltage wave output, when said electrode assembly is moved relative to the biological tissue, wherein said electrode assembly comprises at least one negative electrode and at least one positive electrode proximate to said negative electrode for transmitting electricity from said square voltage wave output through the biological tissue between said positive and negative electrodes.

Abstract
An apparatus for applying electrical current to biological tissue such as skin, bone or muscle. A portable housing can be powered with a battery or attached cord leading to an alternating current or direct current power supply. An extendible arm permits a person to apply the treatment without assistance, and the housing can be operated with a single hand. An amplifier generates a high voltage direct current, and a controller generates a high quality square waveform output. Such waveform comprises an output to an electrode assembly in electrical contact with the biological tissue. The electrode assembly comprises at least one negative electrode and at least one positive electrode which generate an electric current through the biological tissue between the positive and negative electrodes. The electrode assembly is movable relative to the biological tissue so that the current path is continually changing. The electrode assembly can comprise a plurality of negative and positive electrodes to create multiple current paths through the biological tissue. The controller can selectively modify output signal functions such as the amplitude, pulse rate, pulse sweep, frequency, and frequency sweep rate to provide different electrical currents to the biological tissue during operation. A display engaged with the controller indicates the output signal functions and provides controls for selectively modifying the output signal function.
