  • Patent number: 11291843
    Abstract: Devices, systems, and techniques are described for transitioning between different groups of electrical stimulation programs. For example, a system may control delivery of second electrical stimulation defined by one or more second programs of a second group of stimulation programs on a time-interleaved basis with first electrical stimulation defined by one or more first programs of the first group of stimulation programs. The system may change a first ratio of the one or more first programs used to define the first electrical stimulation to the one or more second programs used to define the second electrical stimulation delivered within a first period of time to a second ratio of the one or more first programs used to define the first electrical stimulation to the one or more second programs used to define the second electrical stimulation delivered within a second period of time.

  • Publication number: 20210093851
    Abstract: Techniques are disclosed for defining a homeostatic window for controlling delivery of electrical stimulation therapy to a patient. In one example, a method includes generating and delivering electrical stimulation therapy to tissue of a patient via electrodes. Further, the method includes adjusting a level of a parameter of the electrical stimulation therapy such that a signal of the patient is not less than a lower bound and not greater than an upper bound. The lower bound is determined to be the magnitude of the signal while receiving electrical stimulation therapy sufficient to reduce one or more symptoms of a disease while the patient was receiving medication for reduction of the one or more symptoms. Further, the upper bound is determined to be the magnitude of the signal while receiving electrical stimulation therapy sufficient to reduce the one or more symptoms when the patient was not receiving the medication.
