Abstract

Systems and methods are provided for updating medical devices. An exemplary system includes a medical device and a remote device. The medical device is operable to regulate a condition of a user. The remote device receives measurement data correlative to the condition of the user, determines control information for the medical device based at least in part on the measurement data, and transmits the control information via a first peer-to-peer communication session. The medical device receives the control information via a second peer-to-peer communication session and thereafter regulates the condition of the user based at least in part on the control information and subsequent measurement data.
