A medical device operates in conjunction with a medical device controller. The medical device can include a low-power processor that monitors the states of the medical device. The low-power processor can determine to wake data processors and memory in the medical device based on the states. The data processors can further determine the current versions of executable code and configuration information associated with the data processors by polling a network server or a medical device controller to determine whether at least one update to the current versions is available. If an update is available, the medical device can receive the at least one update from the network server or medical device controller, and deploy it to the appropriate data processor. After deployment the medical device controller can activate the at least one update at a clinically appropriate time.
