Abstract: A method for treating pain or discomfort in a patient is disclosed. The method comprises stimulating a cranial nerve with an electrical signal. The pain or discomfort may be a withdrawal symptom. The cranial nerve may be in an auricular area of the patient. The cranial nerve may be cranial nerve V, cranial nerve VII, cranial nerve IX, cranial nerve X, or branches of greater and lesser occipital nerves thereof and their associated neurovascular bundles. The withdrawal symptom may result from cessation of an opioid. The method may further comprise administering a secondary drug treats one or more of the withdrawal symptoms and addiction. The secondary drug may be administered about one day to about one week after initiating the stimulating step.

Abstract: An auricular peripheral nerve field stimulator includes at least one therapy electrode configured for percutaneous insertion into an auricle of a human ear near at least one neurovascular bundle, and an electrical stimulation device electrically coupled to the at least one therapy electrode, the electrical stimulation device programmed to generate and deliver electrical stimulation signals, with defined stimulation parameters, to the percutaneously inserted at least one therapy electrode to stimulate at least one auricular peripheral nerve field within the auricle, the defined stimulation parameters including a defined signal amplitude, a defined pulse frequency, a defined pulse width, a defined duty cycle and a defined stimulation signal duration.

Abstract: An auricular nerve field stimulation device may include a first plurality of electrodes arranged to contact a ventral aspect of an auricle, a second plurality of electrodes arranged to contact a dorsal aspect of the auricle, and electrical circuitry coupled to the electrodes and configured to selectively apply electrical stimulation signals to the electrodes to cause a first set of trans-auricular currents to flow through the auricle between the first plurality of electrodes and respective ones of the second plurality of electrodes paired therewith according to a first pairing, and to cause a second set of trans-auricular currents to flow through the auricle between the first plurality of electrodes and respective ones of the second plurality of electrodes paired therewith according to a second pairing different from the first pairing, the first and second sets of trans-auricular currents to stimulate at least one auricular nerve field within the auricle.
