Closed-loop therapy adjustment
First Claim
1. A method comprising:
- receiving a plurality of therapy adjustments from a user over time;
determining therapy information for each of the therapy adjustments based on the therapy adjustment;
automatically associating the therapy information with a value of a sensed parameter of a patient for each of the therapy adjustments in response to the therapy adjustment;
subsequently detecting the values of the sensed parameter; and
for each of the detected values, automatically delivering therapy to the patient according to the therapy information associated with the value in response to the 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.

12. A system comprising:
-
a medical device that delivers a therapy to a patient;
a sensor that senses a parameter of the patient;
a user interface; and
a processor that receives a plurality of therapy adjustments over time from a user via the user interface, determines therapy information for each of the therapy adjustments based on the therapy adjustment, automatically associates the therapy information with a value of a sensed parameter of a patient for each of the therapy adjustments in response to the therapy adjustment, subsequently detects the values of the sensed parameter, and, for each of the detected values, automatically controls the medical device to deliver therapy to the patient according to the therapy information associated with the value in response to the detection. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
