Abstract:
1. A method of establishing communication between an external device and an intended implantable medical device, comprising: transmitting from an external device that is unaware of an identifier value of the intended implantable medical device a proximity communication to the implantable medical device, the proximity communication comprising a value that is unique to the external device; transmitting a far field discovery communication from the external device, the far field discovery communication being a far field inquiry from the external device to all implantable medical devices within range of the external device; after transmitting the far field discovery communication, receiving at the external device a far field response communication from a responding implantable medical device, the far field response communication comprising an identifier value that is unique to the responding implantable medical device and a second value; comparing at the external device the second value to the value that is unique to the external device; and if the second value is the same as the value that is unique to the external device, then confirming from the second value that the responding implantable medical device is the intended implantable medical device such that the identifier value of the responding implantable medical device is the identifier value of the intended implantable medical device and exchanging information at the external device with the responding implantable device using far field communication by the external device receiving from the responding implantable medical device the information together with the identifier value that is unique to the responding implantable medical device; confirming by the external device for all subsequent far field communications with the responding implantable medical device that the far field communication is from the intended implantable medical device on the basis of the responding implantable medical device including the identifier value that is unique to the responding implantable medical device in the far field communications.
