ABSTRACT:
A device operable to electrically stimulate living tissue, including body organs, muscles and nerves. The device can be applied to the surface of the body or implanted in the body. The device has an electrical circuit containing a pulse width control for variation of the stimulus intensity, pulse repetition rate, and on-time of the pulse to vary the pulse width. A variation in pulse width causes the stimulus variation of the stimulus intensity in a prescribed mathematical manner so as to approximately follow the curves of the strength-duration pulse stimulus amplitude versus pulse width. This provides for an optimal selection among the various classes of stimulated nerve fibers within a nerve tract or bundle. A precise adjustment of stimulation can be achieved so as to optimize sensation of pain relief.
