Abstract
In some examples, the disclosure relates to system, devices, and techniques for delivering electrical stimulation therapy to treat patient disorders characterized by overactive nerve activity. In one example, the stimulation therapy may include high frequency and low frequency stimulation. The high frequency stimulation may be configured to substantially block overactive pathological nerve activity of the patient and the combination of the high frequency and low frequency simulation may be configured to result in nerve activity that mimics non-pathological nerve activity.
Claims22
A method comprising
- controlling delivery of electrical stimulation therapy to a patient via a medical device, wherein the stimulation therapy includes a plurality of pulse envelopes, each pulse envelope of the plurality of pulse envelopes including a plurality of individual pulses delivered at a first frequency, wherein the plurality of pulse envelopes are delivered at a second frequency less than the first frequency,
- wherein the first frequency is configured such that the stimulation therapy substantially blocks overactive pathological nerve activity of the patient, and wherein the second frequency is configured such that nerve activity not blocked by the stimulation therapy mimics non-pathological nerve activity.
A system comprising:
- a therapy module configured to deliver electrical stimulation therapy to a patient;
- and
- a processor configured to control the therapy module to deliver the stimulation therapy to the patient such that the stimulation therapy includes a plurality of pulse envelopes, each pulse envelope of the plurality of pulse envelopes including a plurality of individual pulses delivered at a first frequency, wherein the plurality of pulse envelopes are delivered at a second frequency less than the first frequency, wherein the first frequency is configured such that the stimulation therapy substantially blocks overactive pathological nerve activity of the patient, and wherein the second frequency is configured such that nerve activity not blocked by the stimulation therapy mimics non-pathological nerve activity.
A system comprising:
- means for delivering electrical stimulation therapy to a patient via a medical device;
- and
- means for controlling the delivery of electrical stimulation therapy to the patient via the medical device, wherein the stimulation therapy includes a plurality of pulse envelopes, each pulse envelope of the plurality of pulse envelopes including a plurality of individual pulses delivered at a first frequency, wherein the plurality of pulse envelopes are delivered at a second frequency less than the first frequency,
- wherein the first frequency is configured such that the stimulation therapy substantially blocks overactive pathological nerve activity of the patient, and wherein the second frequency is configured such that nerve activity not blocked by the stimulation therapy mimics non-pathological nerve activity.
A non-transitory computer-readable storage medium comprising instructions that cause a processor to:
- control a therapy module to deliver electrical stimulation therapy to a patient via a medical device, wherein the stimulation therapy includes a plurality of pulse envelopes, each pulse envelope of the plurality of pulse envelopes including a plurality of individual pulses delivered at a first frequency, wherein the plurality of pulse envelopes are delivered at a second frequency less than the first frequency,
- wherein the first frequency is configured such that the stimulation therapy substantially blocks overactive pathological nerve activity of the patient, and wherein the second frequency is configured such that nerve activity not blocked by the stimulation therapy mimics non-pathological nerve activity.
