EVALUATING PATIENT INCONTINENCE
First Claim
1. A method comprising:
- detecting a sleep state of a patient afflicted with sleep event voiding;
monitoring an activity level of the patient via an implanted medical device; and
determining a number of interruptions in the sleep state of the patient based on the monitored activity level to evaluate the sleep event voiding.

Abstract
Systems and methods for determining a number of interruptions in a sleep state of a patient attributable to an urge or need to void during a sleep event include monitoring an activity level of the patient. The urge or need to void may be attributable to fecal or urinary incontinence. The patient activity level may be determined with one or more sensors that detect motion and/or one or more sensors that monitor a physiological parameter of the patient that varies as a function of patient activity. In one embodiment, a clinician selects a therapy parameter set for the patient based on the severity of the patient'"'"'s incontinence. In another embodiment, the number of interruptions in the sleep state is associated with a therapy parameter set that was implemented during the sleep state in order to evaluate the efficacy of the therapy parameter set. In another embodiment, a medical device automatically adjusts a therapy parameter to treat the incontinence if the number of interruptions in the sleep state exceeds a threshold.

26. A system comprising:
-
an implantable activity sensor that generates a signal that varies as a function of activity of a patient; and at least one processor that receives the signal from the activity sensor, detects a sleep state of the patient, determines a first number of interruptions in the sleep state of the patient based signal, and determines a second number of sleep event voiding events based on the number of interruptions in the sleep state of the patient. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. A system comprising:
-
an activity sensor that generates a signal that varies as a function of activity of a patient; a therapy delivery module configured to deliver a therapy to the patient to control sleep event voiding; and a processor that receives the signal from the activity sensor, detects a sleep state of the patient, determines a number of interruptions in the sleep state of the patient based on the signal, and adjusts a parameter of the therapy based on the number of interruptions in the sleep state. - View Dependent Claims (40, 41, 42)
