1. An implantable electrical stimulator for neural prosthesis powered by an operative in response to an externally applied radio frequency (RF) signal having a power component and a control component for producing stimulation pulses operative to stimulate function of muscles and organs in a patient comprising:

  • a power storage circuit responsive to the power component of the RF signal for storing energy to a selected level at least sufficient to power the electrical stimulator;

    a control circuit coupled to the power storage circuit for receiving stored energy therefrom and being operative to produce the stimulation pulses at a selectable output level and rate; and

    a control circuit coupled between the power storage circuit of the pulse generating circuit being responsive to the energy level stored in the storage circuit for controlling the output level and rate of the stimulator pulses In accordance therewith.
