Abstract

A communication pathway is established between an implanted medical device (IMD) and a proximate electronic device. Performance of one or more functions by the electronic device is known to have a potential to cause at least one adverse effect on the implanted medical device. The implanted medical device can wirelessly conveying a message over the communication pathway to the electronic device detailing an existence of the implanted medical device (IMD) within wireless communication range of the electronic device and detailing a safety requirement or operational data specific to the implanted medical device. The conveyance of the message from the implanted medical device can place the proximate electronic device on notice to minimize the adverse effects on the implanted medical device resulting from executing the one or more functions.
