1. A method comprising:

  • monitoring, by a low-power processor at a medical device, a power state of the medical device;

    determining, by the low-power processor, to periodically wake at least one data processor and memory in the medical device based on the power state, wherein the determining to periodically wake comprises causing the at least one data processor and memory to exit a fully off state by enabling the at least one data processor and memory to operate, wherein the low-power processor and the at least one data processor are different processors, wherein the low-power processor increases a frequency of periodically waking the at least one data processor when the power state indicates that the medical device is attached to an external power source, and wherein the low-power processor decreases the frequency of periodically waking the at least one data processor when the power state indicates that medical device is attached to a battery;

    waking the at least one data processor and memory in the medical device;

    determining, at the medical device, a first current version of executable code associated with the at least one data processor and a second current version of configuration information associated with the at least one data processor;

    polling at least one of a network server and a medical device controller to determine whether at least one of a first update to the first current version of executable code and a second update to the second current version of configuration information are available for the at least one data processor;

    receiving the at least one of the first update and the second update from the network server;

    deploying the at least one of the first update and the second update to an appropriate one of the at least one data processor; and

    activating the at least one of the first update and the second update at a clinically appropriate time, wherein the medical device controller operates in conjunction with the medical device, wherein the clinically appropriate time comprises a time at which the at least one of the first update and the second update will not interfere with patient therapy.
