Systems for treatment of a neurological disorder using electrical nerve conduction block
One aspect of the present disclosure is a system including a waveform generator, a controller, and an electrical contact. The waveform generator is for generating an electrical nerve conduction block (ENCB). The controller is coupled with the waveform generator. The controller is configured to receive an input comprising at least one parameter to adjust the ENCB. The electrical contact is coupled with the wave-form generator. The electrical contact is configured to be placed into contact with a nerve. The electrical contact comprises a high charge capacity material that prevents formation of damaging electro-chemical products at a charge delivered by the ENCB. The electrical contact is configured to deliver the ENCB to the nerve to block transmission of a signal related to a pain through the nerve.
