Abstract
Techniques for remotely calibrating an implanted patient sensor with a remote networking device are described. In some embodiments, the sensor is a component of an implantable medical device (IMD). The remote networking device communicates with the IMD via a network to which the IMD and/or external programmer is connected. The IMD may transmit sensor information to the remote networking device when the IMD detects a problem with the sensor or when the patient indicates that therapy is not correctly selected for different activities. New calibration settings may be remotely generated by directly interrogating the sensor and/or communicating with the patient in order to associate sensor output with patient activities, motions, or postures.
