"In another embodiment, the invention provides an implantable medical device including a processor and a memory. The memory stores instructions that, when executed by the processor, cause the implantable medical device to identify an external device that sent a message and then determine whether to process the message based in part on the identity of the external device that sent the message. The implantable medical device is configured to receive a message from an external device and identify an external device ID in the received message. The external device ID identifies the external device that sent the message. The implantable medical device is also configured to then compare the external device ID from the message to a stored list of approved external device IDs and to process the message when the external device ID matches one of the approved external device IDs in the stored list of approved external device IDs. The message is disregarded when the external device ID does not match any of the approved external device IDs in the stored list of approved external device IDs.
"In another embodiment, the invention provides a method of communicating between an implanted medical device implanted in a patient and an external device external to the patient. The external device initiates communication with one or more implanted medical devices within range of the external device. The external device then sends a message to at least one of the implanted devices. The message includes an external device ID of the external device. The external device then receives a response message indicating whether the external device ID matches an external device ID from a list of approved external device IDs stored on a memory of the implanted medical device. When the response message indicates that the external device ID matches an approved external device ID, the external device stores an implanted device ID corresponding to the implanted device to a memory or the external device and sends subsequent command messages to control the operation of the implanted medical device corresponding to the stored implanted device ID.
"Other aspects of the invention will become apparent by consideration of the detailed description and accompanying drawings.
