Closed-loop therapy adjustment
First Claim
1. A method comprising:
- sensing a parameter of a patient via a sensor; and
,using one or more processors;
receiving a plurality of therapy adjustments from a user over time, wherein each of the plurality of therapy adjustment received from the patient comprises an adjustment of a value of at least one parameter of the therapy delivered by the medical device to the patient;
determining therapy information for each of the therapy adjustments based on the therapy adjustment;
determining, for each of the plurality of therapy adjustments, a value of the sensed parameter in response to the receipt of the therapy adjustment from the patient;
automatically associating the therapy information with the value of the sensed parameter of the patient for each of the therapy adjustments in response to receipt of the therapy adjustment;
subsequently detecting the values of the sensed parameter; and
for each of the detected values, automatically controlling delivery of therapy to the patient according to the therapy information associated with the value in response to the subsequent detection.

Abstract
Techniques for detecting a value of a sensed patient parameter, and automatically delivering therapy to a patient according to therapy information previously associated with the detected value, are described. In exemplary embodiments, a medical device receives a therapy adjustment from the patient. In response to the adjustment, the medical device associates a sensed value of a patient parameter with therapy information determined based on the adjustment. Whenever the parameter value is subsequently detected, the medical device delivers therapy according to the associated therapy information. In this manner, the medical device may “learn” to automatically adjust therapy in the manner desired by the patient as the sensed parameter of the patient changes. Exemplary patient parameters that may be sensed for performance of the described techniques include posture, activity, heart rate, electromyography (EMG), an electroencephalogram (EEG), an electrocardiogram (ECG), temperature, respiration rate, and pH.
