Patent ID: 8849371

Claim:
A method of analyzing and treating abnormality of human or animal tissues, comprising the steps of: outputting by a pulse generator circuit a sequence of electrical pulses at a pulse frequency, the electrical pulses having a pulse width, the pulse generator circuit including current and voltage limiting means; the pulse generator controlling the pulse frequency and the pulse width of the electrical pulses, wherein the pulse width is not less than 0.34 milliseconds and is not greater than 0.74 milliseconds, wherein the maximum current output of the pulse generator circuit is not greater than 8.9 milliamps, wherein the maximum charge of electrical pulse does not exceed 7 micro-coulombs, and wherein the pulse frequency does not exceed 1 GHz when treating a pain condition of a patient; contacting a body of the patient by a pair of probes that are electrically coupled to the pulse generator via respective electrodes separately connected to the patient treatment unit by respective first and second wires, wherein the electrical pulses are substantially rectangular pulses when the probes have an open circuit between them, wherein one of the probes includes a potentiometer for adjusting a characteristic of the electrical pulses; sensing, using a voltage and current sensing circuit, a voltage or a current via the probes when contacting the body of the patient, wherein a peak voltage of the electrical pulses across the probes when a 500 ohm resistance is present across the probes does not exceed 4 volts; and detecting an overvoltage or an overcurrent in the electrical pulses.
