Abstract

An apparatus for applying a signal to a nerve for the treatment of a disorder includes a first electrode and a second electrode. Each of the electrodes is adapted to be secured to a nerve of a patient. A signal generator is electrically connected to each of the first and second electrodes. The signal generator is adapted to create a signal having a first waveform at the first electrode and a second waveform at the second electrode. The waveforms have parameters selected to block propagation of neural action potentials. The waveforms have a repeating pattern of cycles of pulses with a delay period between at least selected ones of said pulses. In one embodiment, the first and second waveforms are out of phase for a cycle of one of the waveforms to occur during a delay period of the other of the waveforms.
