Collecting sleep quality information via a medical device
First Claim
1. A method comprising:
- monitoring a level of melatonin within a bodily fluid of a patient via a medical device that delivers a therapy to the patient;
determining, with a processor, a plurality of values of a metric that is indicative of sleep quality over time, each of the values of the sleep quality metric determined based on the melatonin levels that were determined during delivery of the therapy according to at least one of a plurality of therapy parameter sets;
for each of the plurality of sleep quality metric values, identifying, with the processor, at least one of the plurality of therapy parameter sets used to deliver the therapy by the medical device when the sleep quality metric value was determined;
associating, with the processor, each of the determined values of the sleep quality metric values with the at least one of the plurality of therapy parameter sets;
for each of the plurality of therapy parameter sets, determining, with the processor, a representative value of the sleep quality metric based on the values of the sleep quality metric associated with the therapy parameter set; and
for each of the plurality of therapy parameter sets, storing, with the processor, the representative value associated with the therapy parameter set in a computer-readable memory.

Abstract
At least one of a medical device, such as an implantable medical device, and a programming device determines values for one or more metrics that indicate the quality of a patient'"'"'s sleep. Sleep efficiency, sleep latency, and time spent in deeper sleep states are example sleep quality metrics for which values may be determined. In some embodiments, determined sleep quality metric values are associated with a current therapy parameter set. In some embodiments, a programming device presents sleep quality information to a user based on determined sleep quality metric values. A clinician, for example, may use the sleep quality information presented by the programming device to evaluate the effectiveness of therapy delivered to the patient by the medical device, to adjust the therapy delivered by the medical device, or to prescribe a therapy not delivered by the medical device in order to improve the quality of the patient'"'"'s sleep.

7. A method comprising:
-
delivering a therapy to a patient; monitoring, with a processor, a plurality of signals, each of the signals generated by a sensor as a function of a level of melatonin within a bodily fluid of the patient; identifying when the patient is attempting to sleep; identifying, with the processor, when the patient is asleep based on at least one of the signals; and determining, with the processor, a value of a metric that is indicative of sleep quality based on the identifications of when the patient is attempting to sleep and when the patient is asleep; associating, with the processor, the sleep quality metric value with a therapy parameter set used to deliver the therapy to the patient at least one of when the patient was attempting to sleep and when the patient was asleep; and storing, with the processor, the sleep quality metric value and the associated therapy parameter set in a computer-readable memory. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
