Implantable medical device providing adaptive neurostimulation therapy for incontinence
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.
1. A method for use with a patient having a comfort level, comprising:
receiving, in an external programmer, information relating to efficacy of neurostimulation therapy delivered by an implanted neurostimulator to manage fecal incontinence, wherein the received information comprises information input from the patient;
adjusting, in a processor, one or more stimulation parameters of the neurostimulation therapy based on the received information and adaptation logic; and
inputting the adjusted parameters from the processor to the implanted neurostimulator;
wherein the information is information regarding fecal voiding, information regarding comfort, information regarding a need for different settings, or some combination thereof;
wherein the information regarding comfort is information regarding a subjective rating of the comfort level of the patient.
2. The method of claim 1 , wherein the information regarding fecal voiding comprises at least one of fecal voiding attempts, involuntary fecal voiding, timing of fecal voiding, or characteristics of a fecal bolus.
