Far field telemetry communication with a medical device during a recharge session where a prior pairing with the medical device may not exist
First Claim
1. A method of creating a recharging session between an implantable medical device to be recharged and an external device, comprising:
- while the implantable medical device stores a programming session key, exchanging a recharge key between the external device and the implantable medical device to be recharged;
beginning a recharge session through a proximity wireless recharge coupling between the external device and the implantable medical device to be recharged;
exchanging information related to the recharge session over a far field telemetry connection between the external device and the implantable medical device to be recharged using the recharge key; and
discontinuing current and future use of the recharge key upon termination of the recharge session while the implantable medical device continues to store and utilize the programming session key for programming sessions.

Abstract
Far field telemetry communications are conducted during recharge sessions between an external device and an implantable medical device. The two devices may not have been previously paired together for far field telemetry and may have been paired with other devices for far field telemetry during previous recharge sessions and/or programming sessions. Embodiments provide for temporary bonding of the two devices for far field telemetry during the recharge session. The implantable medical device of the recharge session may maintain a programming bond with an external device other than the external device conducting the recharge session. Safeguards against establishment of inadvertent programming sessions between the external device that has conducted a recharge session and implantable medical devices that may or may not be bonded to that external device are provided.

17. A method of creating a recharging session between an implantable medical device to be recharged and an external device, comprising:
-
storing at the external device an identifier of a program bonded implantable medical device; exchanging an identifier of the implantable medical device to be recharged between the external device and the implantable medical device to be recharged; providing an external annunciation indicating whether the implantable medical device to be recharged is the program bonded implantable medical device based on a comparison of the stored identifier to the exchanged identifier; beginning a recharge session through a proximity wireless recharge coupling between the external device and the implantable medical device to be recharged; and exchanging information related to the recharge session over a far field telemetry connection between the external device and the implantable medical device to be recharged. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method of creating a recharging session between an implantable medical device to be recharged and an external device, comprising:
-
storing at the external device a programming session key and an identifier of an implantable medical device that is program bonded by the programming session key; exchanging an identifier of the implantable medical device to be recharged between the external device and the implantable medical device to be recharged; beginning a recharge session through a proximity wireless recharge coupling between the external device and the implantable medical device to be recharged; exchanging information related to the recharge session over a far field telemetry connection between the external device and the implantable medical device to be recharged; detecting whether the identifier of the implantable medical device to be recharged matches the identifier of the program bonded implantable medical device; and if the identifier of the implantable medical device to be recharged does not match the identifier of the program bonded implantable medical device, then deleting the programming session key stored at the external device. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A medical system, comprising:
-
an implantable medical device to be recharged; and an external device, wherein the external device; stores a programming session key and an identifier of an implantable medical device that is program bonded by the programming session key, receives an identifier of the implantable medical device to be recharged from the implantable medical device to be recharged, begins a recharge session through a proximity wireless recharge coupling between the external device and the implantable medical device to be recharged, exchanges information related to the recharge session over a far field telemetry connection between the external device and the implantable medical device to be recharged, detects whether the identifier of the implantable medical device to be recharged matches the identifier of the program bonded implantable medical device, and if the identifier of the implantable medical device to be recharged does not match the identifier of the program bonded implantable medical device, then deletes the programming session key stored at the external device.
