Extracranial implantable devices, systems and methods for the treatment of neuropsychiatric disorders
First Claim
1. A method for treating a neuropsychiatric disorder by trigeminal nerve stimulation, comprising:
- implanting a subcutaneous electrode assembly below an epidermis and above a pericranium of a patient so that a first electrode contact is in contact with an ophthalmic nerve on one side of the patient'"'"'s forehead and so that a second electrode contact is in contact with an ophthalmic nerve on an opposing side of the patient'"'"'s forehead; and
applying electrical signals to the electrode assembly so that current flows at the first electrode contact and the second electrode contact at specified operational parameters to treat the neuropsychiatric disorder, wherein the electrical signals are applied to minimize current penetration into a brain of the patient such that a charge density at the brain'"'"'s surface does not exceed 20 μ
C/cm2.

Abstract
The present disclosure relates to methods, devices, and systems used for the treatment of mood, anxiety, cognitive, and behavioral disorders (collectively, neuropsychiatric disorders) via stimulation of the superficial elements of the trigeminal nerve (“TNS”). More specifically, minimally invasive systems, devices and 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, nasal and mentalis nerves (also referred to collectively as the superficial trigeminal nerve) are disclosed herein.
