    摘要: A method and external device for providing sub-perception stimulation to a patient via an implantable stimulator device is disclosed. Stimulation parameters for the patient are determined that provide sub-perception stimulation to address a symptom of the patient. A schedule is determined to provide scheduled boluses of stimulation, where each bolus comprises a duration during which stimulation is applied to the patient in accordance with the stimulation parameters, and where the scheduled boluses are separated by off times when no stimulation is provided to the patient. Preferably, the duration of each of the scheduled boluses is 3 minutes or longer, and the duration of each of the off times is 30 minutes or greater. Additional boluses can be provided on demand in addition to the scheduled boluses by selecting an option on the external device, although the provision of such additional boluses may be constrained by a lockout period.

    摘要: This disclosure provides an SCS system comprised of an adaptive IPG. The IPG selectively chooses certain burst pulse parameters according to a pattern of frequencies and amplitudes that are determined by a low power hardware circuit. Alternatively, the patterns of frequencies and amplitudes are dictated by a predetermined list of parameters from a table of limited length. The IPG also is capable of receiving and storing vital sign telemetry, and spinal cord position to train an adaptive neural network to produce paresthesia pulses. Training of the IPG takes place after closing. Retraining the neural network allows the system to adapt to habituation, lead migration, and physiological changes in the patient's condition to maintain efficacy of the system over time. Training the neural network is also accomplished outside the IPG by a separate processor, which serves to conserve battery power and facilitate frequent retraining.

    摘要: The present disclosure provides a medical device (100) for electrical stimulation. The medical device (100) includes electric circuitry configured to perform active charge compensation, said electric circuitry being connectable to at least one electrode arrangement (102) for electrical stimulation. The electric circuitry includes monitoring means configured to monitor at least one voltage associated with a stimulation network (108, 116); at least one variable resistive element configured to provide an voltage drop used in the active charge compensation: and adjustment means configured to dynamically adjust a resistance value of the at least one variable resistive element during the active charge compensation based on the at least one monitored voltage, wherein the adjustment means (202) is a finite state machine for neurostimulation.
