Abstract

Far field telemetry operations are conducted between an external device and an implantable medical device while power is being transferred to the implantable medical device for purposes of recharging a battery of the implantable medical device. The far field operations may include exchanging recharge information that has been collected by the implantable medical device which allows the external device to exercise control over the recharge process. The far field operations may include suspending far field telemetry communications for periods of time while power continues to be transferred where suspending far field telemetry communications may include powering down far field telemetry communication circuits of the implantable medical device for periods of time which may conserve energy. The far field operations may further include transferring programming instructions to the implantable medical device.

First claim

What is claimed is:

1. A method of recharging an implantable medical device, comprising:
a first external device communicating with the implantable medical device via a first communication protocol to begin a communication session for a recharge session and providing recharge energy to the implantable medical device according to a data command during the recharge session; and
a second external device communicating with the first external device via a second communication protocol that is different than the first communication protocol and that is a radio frequency protocol to provide the data command.

2. The method of claim 1 , wherein the second communication protocol utilizes propagation of a wave including an E-field.

3. The method of claim 2 , wherein the second communication protocol comprises a wireless communication protocol for communicating over a distance greater than a distance between the first external device and the implantable medical device.

4. The method of claim 1 , wherein the first communication protocol comprises a near field telemetry protocol.

5. A system for recharging an implantable medical device, comprising:
a first external device that communicates with the implantable medical device via a first communication protocol to begin a communication session for a recharge session and providing recharge energy to the implantable medical device according to a data command during the recharge session; and
a second external device that communicates with the first external device via a second communication protocol that is different than the first communication protocol and that is a radio frequency protocol to provide the data command.

6. The system of claim 5 , wherein the second communication protocol utilizes propagation of a wave including an E-field.

7. The system of claim 6 , wherein the second communication protocol comprises a wireless communication protocol for communicating over a distance greater than a distance between the first external device and the implantable medical device.

8. The system of claim 5 , wherein the first communication protocol comprises a near field telemetry protocol.

9. A system, comprising:
an implantable medical device;
a first external device that communicates with the implantable medical device via a first communication protocol to begin a communication session for a recharge session and providing recharge energy to the implantable medical device according to a data command during the recharge session; and
a second external device that communicates with the first external device via a second communication protocol that is different than the first communication protocol and that is a radio frequency protocol to provide the data command.

10. The system of claim 9 , wherein the second communication protocol utilizes propagation of a wave including an E-field.

11. The system of claim 10 , wherein the second communication protocol comprises a wireless communication protocol for communicating over a distance greater than a distance between the first external device and the implantable medical device.

12. The system of claim 9 , wherein the first communication protocol comprises a near field telemetry protocol.

13. The system of claim 9 , wherein the first external device comprises a near field inductive driver circuit.

14. The system of claim 9 , wherein the first external device comprises an RF antenna.

15. The system of claim 9 , wherein the second external device is configured to connect to a telephone network.

16. The system of claim 9 , wherein the second external device is a handheld device.

17. The system of claim 9 , wherein the second external device is configured to provide programming instructions for the implantable medical device.

18. The system of claim 17 , wherein the second external device provides programming instructions for the implantable medical device by the first external device receiving the programming instructions from the second external device and providing the programming instructions to the implantable medical device.

19. The system of claim 9 , wherein the second external device communicates with the implantable medical device while the implantable medical device is receiving the recharge energy.

20. The system of claim 19 , wherein the second external device communicates with the implantable medical device by the first external device receiving information from the second external device and providing the information to the implantable medical device.
