The present invention provides methods, devices and systems for transcranial stimulation.

A skull-implantable electrode assembly for delivering pulses of electric current to a patient's brain, comprising a conductor housed in an insulated conduit and threaded through an electrically-conductive cannulated skull screw. Details of the exterior construction are discussed, as well as electrode arrangements and methods of treating a medical ailment of a patient.

A therapy method (for a patient having post-traumatic stress disorder (PTSD)) includes: providing an exposure event, to the patient, which is related to a traumatic event that contributed to the PTSD; and, during a therapy session which includes the exposure event, applying vagus nerve stimulation (VNS). A therapy method (for a patient having a given disorder, e.g., a phobia disorder or an obsessive-compulsive disorder (OCD) or an addiction disorder) includes: providing a therapy event (e.g., an extinction event for a phobia disorder), to the patient, which is related to one or more things that contributed to the given disorder; and during a therapy session which includes the therapy event, applying VNS.

Selective high-frequency spinal cord modulation for inhibiting pain with reduced side effects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient's spinal cord region to address low back pain without creating unwanted sensory and/or motor side effects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.

Methods are provided to treat a neurological disorder in a patient by adjusting connectivity between network nodes in a brain of patient using electrical stimulation. Connectivity between network nodes may be increased by synchronous stimulation at multiple network nodes depending upon the neurological disorder. Also, connectivity may be decreased by asynchronous or randomized stimulation at multiple network nodes depending upon the neurological disorder.

Devices and methods for manipulating devices such as micro-scale devices are provided. The devices can include a tether of various materials surrounded by a stiff body. The tether interfaces with microscale devices to draw them against the stiff body, holding the microscale devices in a locked position for insertion into or extraction out of tissue. The tensional hook and stiff body are configurable in a multitude of positions and geometries to provide increased engagement. Such configurations allow for a range of implantation and extraction surgical procedures for the device within research and clinical settings.

The present disclosure relates to methods, devices and systems used for the treatment of medical disorders via stimulation of the superficial elements of the trigeminal nerve. 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.

The present invention relates to methods of treating or preventing addiction and relapse use of addictive agents and treating or preventing addictive or compulsive behavior and relapse practice of an addictive behavior or compulsion. The methods and compositions of the invention are useful in the treatment or prevention of addiction to any agent, including alcohol, nicotine, marijuana, cocaine, and amphetamines, as well as compulsive and addictive behaviors, including pathological gambling and pathological overeating.
