Abstract: The invention relates to an implantable stimulator electrode for stimulation of nerves adapted to be surgically implanted around a nerve bundle, said stimulator comprising one or more electrode means which, when implanted around said nerve bundle, surrounds the nerve bundle totally or partly. Electrode means and electronic circuit means are coupled to and powered by one or more receiving coils mounted on the stimulator housing. One advantage of the invention is that the electrode, when implanted, acts as a remote addressable maintenance free unit.
