Development of a new implantable bio-telestimulator

The authors describe preliminarily an implantable bio-stimulating device for stimulation of peripheral nerves and the central nervous system. The receiving unit is totally implantable. The system works on radiofrequency transcutaneous coupling across the skin. This new telestimulating device has a wider band width and more flexibility than units currently being used in neurosurgery. The unit is independent of coupling efficiency and is designed to accept any symmetrical or nonsymmetrical waveform within limits listed in this presentation. The unit is designed so as to provide this waveform as a constant current signal at the output of the receiver.
