Devices, systems and methods for treatment of neuropsychiatric disorders
First Claim
1. A system for stimulation of auriculotemporal nerves to treat a neuropsychiatric disorder, the system comprising:
- a pulse generator configured to apply electrical signals at a frequency between approximately 20 and 300 Hertz, at a pulse duration between approximately 50 and 500 microseconds, at an output current density of not greater than approximately 25 mA/cm2 and an output charge density of not greater than approximately 10 microCoulomb/cm2 at the cerebral cortex; and
a cutaneous electrode assembly in electrical communication with the pulse generator, the cutaneous electrode assembly comprising;
a first electrode comprising at least one contact configured for cutaneous placement directly over or adjacent an auriculotemporal nerve on one side of a patient'"'"'s face; and
a second electrode comprising at least one contact configured for cutaneous placement directly over or adjacent another auriculotemporal nerve on the other side of the patient'"'"'s face.

Abstract
The present disclosure relates to methods, devices and systems used for the treatment of mood, anxiety, post traumatic stress disorder, and cognitive and behavioral disorders (collectively, neuropsychiatric disorders) via stimulation of the superficial elements of the trigeminal nerve (“TNS”). More specifically, cutaneous methods of stimulation of the superficial branches of the trigeminal nerve located extracranially in the face, namely the supraorbital, supratrochlear, infraorbital, auriculotemporal, zygomaticotemporal, zygomaticoorbital, zygomaticofacial, infraorbital, nasal and mentalis nerves (also referred to collectively as the superficial trigeminal nerve) are disclosed herein.

12. A method for treating a neuropsychiatric disorder by auriculotemporal nerve stimulation, the method comprising:
-
placing a first electrode of a cutaneous electrode assembly directly over or adjacent to an auriculotemporal nerve on one side of a patient'"'"'s face; placing a second electrode of the cutaneous electrode assembly directly over or adjacent to another auriculotemporal nerve on the other side of the patient'"'"'s face; and applying electrical signals to the cutaneous electrode assembly at specified operational parameters to treat the neuropsychiatric disorder, wherein the applying comprises applying electrical signals at a frequency between approximately 20 and 300 Hertz, at a pulse duration between approximately 50 and 500 microseconds, at an output current density of not greater than approximately 25 mA/cm2 and an output charge density of not greater than approximately 10 microCoulomb/cm2 at the cerebral cortex. - View Dependent Claims (13, 14, 15, 16, 17, 18)
