  • Patent number: 9844673
    Abstract: Example apparatus and methods cause activation of target neural tissue through electrical stimulation of a connected white matter tract to reduce the hyper-excitability of the target neural tissue and thus reduce seizures while preserving memory in humans. Example apparatus and methods apply low frequency (e.g., <10 HZ) electrical stimulation to the forno-dorso-commissure (FDC), detect an electrical signal generated in an area connected to, innervated by, or that can be activated by the FDC in response to the stimulation, and reconfigure the stimulation based on the detected signal and a desired therapeutic effect. The stimulation may be reconfigured to produce an electrical stimulation waveform that will produce the desired therapeutic effect. The desired therapeutic effect may be, for example, reducing hyper-excitability of neural tissue in a target area, reducing hippocampal spikes, reducing seizure odds, or improving recall.

  • Patent number: 9504846
    Abstract: Systems, methods, and devices relating to transcranial magnetic stimulation (TMS). A circuit having at least two inductors is used in a TMS device. A small inductor adjacent to the patient's head and a large inductor away from the patient is used. The inductors are coupled to the circuit using multiple semiconductor switching subsystems. The subsystems, when activated, couple the inductors to the circuit and the inductors act as a single inductance. When deactivated, the subsystems decouple the inductors from the circuit and each inductor individually recovers or dissipates/discharges energy stored within. Since each inductor dissipates energy separately from each other, a much shorter dissipation or recovery time is achieved in the inductor close to the patient's brain as compared to the larger inductor. While dissipating or discharging, the small inductor induces electric currents in the brain to thus achieve stimulation and elicit action potentials.

    Abstract: Methods, devices and systems for Transcranial Magnetic Stimulation (TMS) are provided for synchronous, asynchronous, or independent triggering the firing multiple of electromagnets from either a single power source or multiple energy sources. These methods are particularly useful for stimulation of deep (e.g., sub-cortical) brain regions, or for stimulation of multiple brain regions, since controlled magnetic pulses reaching the deep target location may combine to form a patterned pulse train that activates the desired volume of target tissue. Furthermore, the methods, devices and systems described herein may be used to control the rate of firing of action potentials in one or more brain regions, such as slow or fast rate rTMS. For example, described herein are multiple electromagnetic stimulation sources, each of which are activated independently to create a cumulative effect at the intersections of the electromagnetic stimulation trajectories, typically by means of a computerized calculation.

  • Publication number: 20150025297
    Abstract: Described herein are magnetic neural stimulation systems for the treatment of neurological disorders. One variation of a magnetic neural stimulation system includes magnetic stimulators shaped as helical or ramped coils, where each turn of the coil has an acute turning angle of less than 90 degrees. Also described herein are magnetic neural stimulation systems that include an array of stimulators and one or more shielding components. The shielding components modulate the density profile of the induced eddy currents to increase stimulation to targeted neural tissue regions while decreasing stimulation to non-targeted neural regions. Other variations of magnetic stimulation systems include one or more stimulators and a shield in which some of the induced eddy currents in the shield may act to attenuate the magnetic field in certain regions of the shield.

  • Publication number: 20150018598
    Abstract: A neurostimulation patch is affixed to a patient's skin (e.g., via a medical skin adhesive) and provides stimulation energy for an implanted lead. The patch may be used for SCS trials or other applications where is it desirable to avoid implanting a stimulation device within a patient. Circuitry in the patch generates stimulation signals and couples these signals to the implanted lead. The signals may be coupled to the lead via a direct physical connection or via a wireless connection. In some embodiments, the neurostimulation patch is configured in a manner that enables the patch to be placed immediately above the puncture site where an associated percutaneous lead passes through a patient's skin, thereby protecting the puncture site and facilitating secure routing of the lead.

  • Publication number: 20140371515
    Abstract: Stimulation treatments for medical disorders comprise providing stimulation parameters that create partial stimulation signals which combine into vector signals. The individual partial signals may have frequency or temporal content that is unique rather than all being identical. Vector signals may thus be designed with certain advantageous characteristics such as to influence target tissue in an intended manner while partial signals may be designed with other advantageous characteristics such as to avoid producing side effects in adjacent tissue. Roving of stimulation parameters can be designed to influence partial signals, vectors signals, or both. Partial and vector signals may be designed to match or avoid internal/endogenous activity patterns and rhythms of a patient. Methods for choosing, creating and using partial signals are disclosed. Tissue modulation may be accomplished with electrical and/or magnetic stimulation.
