Transcranial current loop stimulation device

Abstract

A device is described, which provides electrical stimulation to the brain of a person, where the device comprises one or more modules, each module comprising an implantable pulse generator (IPG) and a lead with at least one subcranial electrode, which extends into or near the surface of the brain. Each module's IPG comprises a battery and a subcutaneous electrode. Each module is inserted into a burr hole, and a seal fills the space to minimize electric current flow between the subcutaneous electrode and subcranial electrode.

Description

BACKGROUND OF THE INVENTION[0001]This application claims the benefit of Provisional Application 62 / 711,915 (Attorney Docket No. 51576-705.101), filed on Jul. 30, 2018, the full disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]Electric brain stimulation has been shown to be a potentially effective treatment for a number of brain disorders, including epilepsy, migraine, fibromyalgia, coma, major depression, stroke rehabilitation, and Parkinson's disease, and is also used in electrocorticography and Cortical Stimulation Mapping (CSM). Traditional Deep Brain Stimulation (DBS) is a neurosurgical procedure involving implantation of an Implantable Pulse Generator (IPG) placed under the skin near the collarbone. The IPG is battery powered and sends electrical pulses through a lead, which is routed under the skin to an area near the top of the patient's head, where it separates into two leads, each with its own set of electrodes near the tip. The leads...

Benefits of technology

[0014]Positioning of the electrodes of the device to target a specific region of the brain of the person allows for the treatment of mental disorders and improving a psychological or physiological condition of the person. In one aspect, the lead of each module is configured to be implanted so that one or more of the subcranial electrodes are in or near an anterior nucleus of a thalamus, which allows for the treatment of epilepsy. In one aspect, the lead of each module is configured to be implanted so that one or more of the subcranial electrodes are in or near a nucleus accumbens, which allows for treatment of addiction, such as from alcohol or opioids. In one aspect, the lead of each module is configured to be implanted so that one or more of the subcranial electrodes are in or near a subthalamic nucleus or globus pallidus interna, which allows for the treatment of Parkinson's disease and other movement disorders. In one aspect, the lead of each module is configured to be implanted so that one or more of the subcranial electrodes are in or near a hip
