First Claim
Patent Images
1. A method comprising:
- receiving information sensed by a sensor relating to efficacy of electrical stimulation therapy delivered to a patient by an implanted neurostimulator to manage fecal incontinence, wherein the received information includes information regarding a physiological state of the patient at the time of a voiding event, the information regarding the physiological state of the patient comprising at least one of patient activity type at the time of the voiding event or patient posture at the time of the voiding event;
with a processor, adjusting one or more stimulation parameters of the electrical stimulation therapy based on the received information regarding the physiological state of the patient at the time of the voiding event and adaptation logic; and
providing the adjusted parameters to the implanted neurostimulator.

Abstract
In general, the disclosure is directed to an implantable neurostimulator and system capable of providing adaptive neurostimulation therapy to alleviate urinary or fecal incontinence. The neurostimulator operates according to a set of stimulation parameters stored in memory. During operation, information is obtained from the patient, the implanted neurostimulator, one or more implanted sensors, or some combination thereof. A processor analyzes the information to automatically generate proposed adjustments to the stimulation parameters applied by the neurostimulator. The adjustments provide an adaptive neurostimulation therapy that supports or enhances therapeutic efficacy based on the information.
