Patent abstract
A helical electrode for nerve stimulation includes an insulative helical substrate, having an inner surface, configured to wrap around a nerve. An electrical conductor is disposed upon the inner surface of the substrate. The conductor defines a helix of about one revolution and produces an electric field in which an injected current in similar axons varies by no more than about 25%. The conductor may include tapered end sections, which may be counter-tapered.
