  • Patent number: 11801389
    Abstract: A neuromodulation customization system includes a field definition user interface, a neuromodulation signaling engine, and a supervisor engine. The field definition user interface is to facilitate entry of a customized electrotherapy field definition, with the field definition user interface including a set of input controls for defining field shape, field intensity, and field steering parameters of the customized electrotherapy field. The neuromodulation signaling engine is to produce commands for neuromodulation output circuitry to control generation of a customized electrotherapy field via a set of electrodes based on the customized electrotherapy field definition. The supervisor engine is to assess compliance of the customized electrotherapy field to be generated with applicable predefined criteria, and to modify generation of the customized electrotherapy field in response to an assessed non-compliance with the criteria.

  • Patent number: 10029102
    Abstract: A neuromodulation system and method of providing therapy to a patient. Electrical energy is delivered to the patient in accordance with a modulation parameter, thereby providing therapy to the patient, and the modulation parameter of the delivered electrical energy is varied over a period of time, such that the delivered electrical energy is continually maintained at a sub-threshold level throughout the period of time. The sub-threshold level may be referred to as a patient-perception threshold, which may be referred to as a boundary below which a patient does not sense delivery of the electrical energy. For example, in a spinal cord modulation system, the patient-perception threshold may be a boundary below which a patient does not experience paresthesia.
