  • Patent number: 11975194
    Abstract: Systems and methods for stimulation of neurological tissue generate stimulation trains with temporal patterns of stimulation, in which the interval between electrical pulses (the inter-pulse intervals) changes or varies over time. Compared to conventional continuous, high rate pulse trains having regular (i.e., constant) inter-pulse intervals, the non-regular (i.e., not constant) pulse patterns or trains that embody features of the invention provide a lower average frequency. The systems and methods for stimulation of neurological tissue may be used to increase the efficacy of treatment in patients with Parkinson's Disease.

  • Publication number: 20230248975
    Abstract: Embodiments of the present invention provide systems and methods for the treatment of pain through activation of select neural fibers. The neural fibers may comprise one or more afferent neural fibers and/or one or more efferent neural fibers. If afferent fibers are stimulated, alone or in combination with efferent fibers, a therapeutically effective amount of electrical stimulation is applied to activate afferent pathways in a manner approximating natural afferent activity. The afferent fibers may be associated with primary receptors of muscle spindles, golgi tendon organs, secondary receptors of muscle spindles, joint receptors, touch receptors, and other types of mechanoreceptors and/or proprioceptors. If efferent fibers are stimulated, alone or in combination with afferent fibers, a therapeutically effective amount of electrical stimulation is applied to activate intrafusal and/or extrafusal muscle fibers, which results in an indirect activation of afferent fibers associated therewith.

  • Publication number: 20230028428
    Abstract: Systems and methods for stimulation of neurological tissue and generation stimulation trains with temporal patterns of stimulation, in which the interval between electrical pulses (the inter-pulse intervals) changes or varies over time. The features of the stimulation trains may be selected and arranged algorithmically to by clinical trial. These stimulation trains are generated to target a specific neurological disorder, by arranging sets of features which reduce symptoms of that neurological disorder into a pattern which is effective at reducing those symptoms while maintaining or reducing power consumption versus regular stimulation signals. Compared to conventional continuous, high rate pulse trains having regular (i.e., constant) inter-pulse intervals, the non-regular (i.e., not constant) pulse patterns or trains that embody features of the invention provide increased efficacy and/or a lower than average frequency.

  • Publication number: 20220323765
    Abstract: The present invention relates to methods that enable one to design temporal patterns for the optimal stimulation of a nervous system, one or more nerve cells, or nervous tissue. In one embodiment, the present invention relates to methods to design improved stimulation patterns and/or genetic algorithms for the optimal stimulation of a nervous system, one or more nerve cells, or nervous tissue. In one embodiment, the present invention utilizes a model-based design to achieve a more optimal stimulation pattern for use in connection with a nervous system, one or more nerve cells, or nervous tissue (e.g., a human nervous system). In another embodiment, the model-based design of the present invention utilizes a systematic search method to identify parameters (e.g., design variables) that minimize a cost function (e.g., optimize the fitness of a particular design).

  • Patent number: 11357983
    Abstract: Systems and methods for applying electrical stimulation to different sub-populations of targeted neurological tissue for optimizing spinal cord stimulation are disclosed. According to an aspect, a method includes applying a first pattern of electrical stimulation to a first sub-population of targeted neurological tissue of a subject. The method also includes applying a second pattern of electrical stimulation to a second sub-population of targeted neurological tissue of the subject, the second pattern of electrical stimulation being applied at a different frequency than the first pattern of electrical stimulation.
