  • Patent number: 11883670
    Abstract: Systems and methods for producing asynchronous neural responses to treat pain and/or other patient conditions are disclosed. A method in accordance with a particular embodiment includes selecting a target stimulation frequency that is above a threshold frequency, with the threshold frequency corresponding to a refractory period for neurons of a target sensory neural population. The method can further include producing a patient sensation of paresthesia by directing an electrical signal to multiple sensory neurons of the target sensory neural population at the stimulation frequency, with individual neurons of the sensory neural population completing corresponding individual refractory periods at different times, resulting in an asynchronous sensory neuron response to the electrical signal.

    Abstract: Spinal cord modulation for inducing paresthetic and anesthetic effects, and associated systems and methods are disclosed. A representative method in accordance with an embodiment of the disclosure includes creating a therapeutic effect and a sensation in a patient by delivering to the patient first pulses having a first set of first signal delivery parameters and second pulses having a second set of second signal delivery parameters, wherein a first value of at least one first parameter of the first set is different than a second value of a corresponding second parameter of the second set, and wherein the first pulses, the second pulses or both the first and second pulses are delivered to the patient's spinal cord.

  • Patent number: 11786731
    Abstract: Selective high-frequency spinal chord modulation for inhibiting pain with reduced side affects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient's spinal chord region to address low back pain without creating unwanted sensory and/or motor side affects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.
