  • Patent number: 11167154
    Abstract: A system for use in managing a neuromodulation therapy includes an ultrasound transducer array controlled by a control unit to deliver ultrasound waveforms for causing modulation of neural tissue in a patient. The system acquires data indicating a response to the modulation, analyzes the acquired data to determine correlation data between a response to the modulation and an ultrasound control parameter, and reports the correlation data to enable identification of at least one therapy parameter to be used to deliver a neuromodulation therapy to the patient by a therapy delivery system.

  • Publication number: 20210299442
    Abstract: In some examples, a technique for delivering electrical stimulation therapy to a patient includes determining, by processing circuitry, one or more cycle settings associated with delivery of the electrical stimulation therapy, determining, by the processing circuitry, a cycle time period associated with each cycle setting, and delivering, by a medical device, electrical stimulation therapy based on the determined cycle settings and the determined cycle time periods. Each cycle setting may define an on-cycle, during which electrical stimulation is delivered, and an off-cycle, during which electrical stimulation is not delivered. The technique further may include delivering electrical stimulation to the patient to provide one or more reminders to the patient, such as a reminder to void or a reminder of the existence of electrical stimulation.

  • Publication number: 20210052890
    Abstract: Systems, devices, and techniques are disclosed for predicting a urinary event of a patient. In one example, a system comprises a fluid consumption cup comprising one or more sensors. The system may comprise communication circuitry configured to receive, from the fluid consumption cup, one or more signals that indicate an amount of fluid removed from the fluid consumption cup. The system may comprise processing circuitry configured to: update a patient log based on the one or more signals that indicate the amount of fluid removed from the fluid consumption cup; determine that the urinary event is predicted to occur, the occurrence of the urinary event predicted based on the patient log; and provide, in response to the determination and for receipt by the patient, a notification that the urinary event is predicted to occur.
