Abstract
An electrical stimulation system for selectively stimulating portions of the body. The system includes an external device for alternately transmitting stimulus signals and control signals to an implantable receiver. The receiver includes a plurality of output devies adapted to apply the stimulus signals to the body and circuitry for routing the stimulus signal to the output devices under the control of the control signals. In a preferred embodiment, the control signals are formed of an alterably preselected number of pulse signals with the routing circuitry routing each of the stimulus signals to the output devices in predetermined correspondance with the number of pulse signals within a different one of the control signals. The system of the present invention may be employed to sequentially stimulate several stimulation sites, with the stimulation sites being selected to combat the same or different body disfunctions. Alternatively, the system of the present invention may be employed to repetitively stimulate the same stimulation sites while allowing an alteration in the stimulation sites to combat nerve fatigue or to provide a more effective electrode configuration, for example.
