Automatic validation techniques for validating operation of medical devices
First Claim
1. A method of testing a medical device, comprising:
- recording therapy parameter values describing therapy being delivered to a patient;
recording a sequence of patient parameter values indicative of at least one of posture and activity of the patient occurring while the therapy is being delivered;
controlling an automated device to reproduce the sequence of patient parameter values; and
validating that the medical device is delivering therapy in accordance with the recorded therapy parameter values while the medical device is experiencing conditions resulting from controlling of the automated device.

Abstract
Techniques for validating operation of a medical device are disclosed. A data collection phase utilizes a first sensor carried by a patient to record patient parameter values indicative of conditions experienced by the patient (e.g, posture states.) Therapy parameter values describing therapy adjustments requested by the patient in response to the conditions are also recorded. Associations formed between the therapy parameter values and the patient parameter values are used to develop a closed-loop algorithm for control of an IMD having a sensor similar to the first sensor. An automated device such as a robotic arm uses the recorded patient parameter values to automatically reproduce, and to subject the IMD to, conditions present during the data collection phase. Therapy delivered by the IMD while under control of the closed-loop algorithm and while being subjected to the conditions is compared to the recorded therapy parameter values e to validate IMD operation.
