Patent ID: 8731676

Claim:
A method of ameliorating sensory nerve pain in a patient in need thereof, the method comprising (a) connecting a waveform generator operatively to an implanted electrode contacting a trunk of a sensory peripheral nerve having a diameter exceeding 3 mm and up to 12 mm in the patient, resulting in prevention of action potential transmission in the nerve upon application of a waveform of at least 5 kHz up to 50 kHz where the frequency blocks but does not stimulate and is not used to generate an action potential in a nerve but rather to block conduction of an action potential at one of a voltage ranging from 4 Vpp to 20 Vpp, or a current ranging from 4 mApp to 26 mApp at a plurality of contact surfaces with the nerve trunk for an interval sufficient to effect substantially immediate pain relief in the patient, and (b) optionally repeating step (a) as needed to ameliorate nerve pain.
