Abstract
Described herein are techniques to ensure a user using an external device is authorized to connect and connecting to a correct implantable medical device using a wireless communication protocol. A request for authorization is sent to the external device from the implantable medical device, and the authorization can be provided by an authorization pulse sent using the implantable medical device charger over the inductive link between the charging device and the implanted device. The authorization pulse can be trusted because the inductive link is short range, ensuring the patient is aware of the connection to the implanted device. Once the implanted device receives the authorization pulse, it may finalize the pairing over the first connection.
