A coil configuration and method for transcranial magnetic stimulation enabling stimulation of deep regions of the brain without excessively stimulating the cortex is provided. The coil configuration utilizes at least one coil to produce an off-plane magnetic field to enhance the magnetic field from a top TMS coil. In one configuration three coils, referred to as the Triple Halo Coil and oriented at +30°, 0°, and −30° relative to the plane of the TMS coil, are used. In another configuration a single variable position coil referred to as the Variable Halo Coil and positionable vertically and/or angularly is used.

A system for integrated electric field simulation and neuronavigation includes a neuronavigation system configured to track an electromagnetic coil used for neuromodulation of a brain of a subject and an electric field simulation neural network coupled to the neuronavigation system. The electric field simulation neural network is configured to generate a simulated electric field for a region of interest based at least on a coil position and orientation, a magnetic field profile of the electromagnetic coil, and multimodal neuroimaging data associated with the subject. The system further includes a display coupled to the electric field simulation neural network and configured to display the simulated electric field. The region of interest can be the brain of the subject and the electromagnetic coil can be a transcranial magnetic stimulation (TMS) coil.

The present disclosure provides, in part, methods of treatment for Alzheimer’s disease comprising applying repetitive transcranial magnetic stimulation (rTMS) therapy to a patient in need thereof. The present disclosure also provides devices that generate a low intensity pulsed magnetic field and variable frequencies.

Described herein are high-power pulsed electromagnetic field (PEMF) applicator apparatuses. These apparatuses are configured to drive multiple applicators to concurrently deliver high-power PEMF signals to tissue. The apparatuses may be further configured to wirelessly communicate with local computing device and a remote server for patient monitoring, prescription and/or device servicing.

A first magnetic field for application to body tissue is generated via a first inductor. A second magnetic field is also generated via a second inductor. Connecting circuitry, including at least first and second branches, is provided between an electric storage device such as a capacitor, or a capacitor arrangement comprising at least a first capacitor, and the first and second inductors. A switch forming part of the first branch electrically connects the electric storage device to the first inductor enabling electrical current to flow through the first branch and the first inductor, thereby causing the first inductor to generate the first magnetic field. The current flowing through the first branch represents a first direction of flow with respect to the electric storage device. A switch forming part of the second branch electrically connects the electric storage device to the second inductor enabling current to flow between the electric storage device and the second inductor through the second branch. The current flowing through the second branch represents a second direction of flow with respect to the electric storage device.

Combined methods for treating a patient using time-varying magnetic field are described. The treatment methods combine various approaches for aesthetic treatment. The methods are focused on enhancing a visual appearance of the patient.

A method comprising detecting an epileptic event in a patient; applying an electrical therapy to a first target area in at least one of a brain region or a cranial nerve of said patient in response to said detecting; receiving a body signal responsive to the electrical therapy, wherein said body signal is selected from an autonomic signal, a neurologic signal, a metabolic signal, an endocrine signal, or a tissue stress marker signal; determining whether said body signal indicates that said electrical therapy has an efficacious effect; and terminating the application of said electrical therapy if the response indicates that the electrical therapy has an efficacious effect. An apparatus capable of performing the method. A non-transitive, computer-readable storage device for storing data that when executed by a processor, perform the method.

A neurostimulation system is disclosed for providing treatment to a patient during a therapy session. The neurostimulation system includes a neurostimulator for transmitting magnetic or electrical signals based upon a treatment program. A programmer is connected to the neurostimulator to set a treatment session parameter value to calculate a therapy compliance value. A compliance module is connected to the neurostimulator and the programmer to calculate and store a therapy compliance value. A control module is connected to the compliance module, the programmer and the neurostimulator and determines whether the therapy compliance value is within a range of the treatment program. The neurostimulator transmits electrical or magnetic signals to the patient in a treatment session only if the therapy compliance value meets a compliance criteria.

An implantable medical device (IMD) includes one or more stimulation engines (SEs) and selectively connectable output switching circuitry for driving a plurality of output nodes associated with a respective plurality of electrodes of the IMD's lead system when implanted in a patient. The output switching circuitry may be configured to facilitate self-test mode (STM) functionality in the IMD (e.g., when it is in a hermetically sealed package) by using a dual mode switch in series with a stimulation engine selection switch with respect to each output node in the output switching circuitry under mode selection control.

Devices, systems and methods are disclosed for treating or preventing an autism spectrum disorder, a pervasive developmental disorder, or a disorder of psychological development. The methods comprise transmitting impulses of energy non-invasively to selected nerve fibers, particularly those in a vagus nerve. The nerve stimulation may be used as a behavior conditioning tool, by producing euphoria in an autistic individual. Vagus nerve stimulation is also used to modulate circulating serotonin levels in a pregnant woman so as to reduce the risk of having an autistic child; modulate the levels of growth factors within a child; promote balance of neuronal excitation/inhibition; modulate the activity of abnormal resting state neuronal networks; increase respiratory sinus arrhythmia; and avert episodes of motor stereotypies with the aid of forecasting methods.
