Electrotherapy and neurostimulation medical device apparatus and method

A method for providing therapeutic electric current to a treatment site of a patient comprising the steps of:

• generating a first and second signal having a frequency difference between 1 Hz and 300 Hz, wherein the first and second signal are two sinusoidal alternating current signals having a base frequency value of between 200 Hz and 500 KHz which are amplified by Class D switching amplifiers;
• coupling a first electrode of at least one pair of electrodes to a patient's body on or beneath a first epidermal or mucous membrane surface;
• coupling a second electrode of at least one pair of electrodes to a patient's body on or beneath a second epidermal or mucous membrane surface;
• and
• forming a therapeutic signal configured to reduce pain at a treatment site by simultaneously sending a first signal from the first electrode to the second electrode and sending a second signal from a second electrode to the first electrode, and then simultaneously sending the first signal from the second electrode back to the first electrode and the second signal from the first electrode back to the second electrode, wherein the first and second signals are linearly independent off phase alternating current signals.

An electro therapy and neurostimulation device comprising:

• a substantially rectangular shape having at least one corner of the outer peripheral edge of the device at an angle, and a depression disposed within the angled portion of the device;
• a female port disposed within the depression configured to receive a male connector;
• and
• wherein the depression comprises a plurality of indentations configured to receive a cable attached to the male connector such that the cable is located against the side edges of the substantially rectangular device when the male connector is inserted into the female port.
