NERVE BLOCKING METHOD AND SYSTEM

摘要

A device for pain relief, bowel and bladder control comprising a cyclical waveform, pulse generate, electrode system to block the propagation of action potentials in the axon only at that site, and a stimulus electrode system to generate action potentials in the axon. The stimulus electrode system is central and flanked on either side by a blocking electrode system. After applying stimulus electrical pulses to a first site on the nerve blocking cyclical waveform pulses are applied to a second site on the nerve. Then the blocking current amplitude is reduced so that the propagation of action potentials remains blocked in some axons but is no longer blocked in pre-selected axons.
