Abstract

The invention is a distributed implantable neuro-stimulation system, comprising an implant controller including control logic to transmit two time-varying power signals, varying between two levels and out of phase with the other, and a command signal modulated onto at least one of the power signals. One or more electrode cells, each having control logic to extract charge from the power signals and recover commands from the command signal. A two-wire bus interconnecting the implant controller and all the electrode cells, to carry one of the time varying signals in each of the two wires, and to carry the command signal.
