  • Patent number: 12036408
    Abstract: Apparatus and methods for managing pain uses separate varying electromagnetic fields, with a variety of temporal and amplitude characteristics, which are applied to a particular neural structure to modulate glial and neuronal interactions as a mechanism for relieving chronic pain. In another embodiment, a single composite modulation/stimulation signal which has rhythmically varying characteristics is used to achieve the same results as separate varying electromagnetic fields. Also, disclosed is an apparatus and method for modulating the expression of genes involved in diverse pathways including inflammatory/immune system mediators, ion channels and neurotransmitters, in both the Spinal Cord (SC) and Dorsal Root Ganglion (DRG) where such expression modulation is caused by spinal cord stimulation or peripheral nerve stimulation using the disclosed apparatus and techniques.

  • Publication number: 20240091539
    Abstract: Systems, devices, and techniques for adjusting electrical stimulation based on sensed ECAP signals. For example, processing circuitry is configured to control delivery of a first train of electrical stimulation pulses at a first frequency to a first target tissue and control delivery of a second train of electrical stimulation pulses at a second frequency to a second target tissue different from the first target tissue. The processing circuitry can also receive an ECAP signal elicited by a pulse of the second train of electrical stimulation pulses, adjust, based on the ECAP signal, a first value of a parameter that at least partially defines the first tram of electrical stimulation pulses to a second value, and, responsive to adjusting the first value of the parameter to the second value, control delivery of subsequent pulses of the first tram of electrical stimulation pulses according to the second value of the parameter.

  • Patent number: 11890473
    Abstract: An apparatus, system and technique selectively eliminates the noxious signal components in a neuronal signal by creating an interfering electrical signal that is tuned to a given frequency corresponding to the oscillatory pattern of the noxious signal, resulting in a modified neuronal signal that substantially reproduces a normal, no-pain neuronal signal. The disclosed system and technique of pain relief is based on the hypothesis that the temporal profile of pain signals encodes particular components that oscillate at unique and quantifiable frequencies, which are responsible for pain processing in the brain.

  • Publication number: 20240009463
    Abstract: Examples for controlling electrical stimulation therapy are described. One example includes delivering a pulse train at a frequency to a patient, the pulse train comprising a plurality of first pulses at least partially interleaved with a plurality of second pulses, wherein the plurality of first pulses are configured to facilitate sensing elicited electrical signals, each pulse of the plurality of first pulses having an active first phase and active second phase. Each pulse of the plurality of second pulses may include an active first phase and a passive second phase. Additionally, or alternatively, the plurality of second pulses may alternate between a cathodic active first phase and an anodic active first phase according to a ratio. At least one pulse of the plurality' of second pulses may have an interphase interval that is longer than an interphase interval of at least one pulse of the plurality of first pulses.

  • Publication number: 20230414945
    Abstract: Disclosed is a method of treating sleep apnea in a patient by operating an implanted neurostimulator implant to stimulate the genioglossus nerve branch and/or the genioglossus muscle. Also disclosed is a method of implanting a neurostimulator implant in the genioglossus muscle proximal to the genioglossus nerve branch. Further disclosed is a sleep apnea treatment system and a guide for the sleep apnea treatment system.
