Abstract
A system for providing neurostimulation includes an external device (“external exciter”) and an implanted device. The external exciter includes an energy source which inductively powers the implanted device. Examples of such external exciters include devices having at least one of: ultrasonic transducers, Radio Frequency (RF) transmitters, and solar cells. The implanted device includes circuitry that limits its maximum energy output to a predetermined saturation threshold such that excess stimulation from the external exciter does not raise the output of the implanted device beyond the saturation threshold. The output signal of the external exciter is then pulse-width modulated in order to produce a desired amount of output stimulation from the implanted device to stimulate the bioelectrically excitable tissue at a desired level.
