Abstract

An implantable medical device comprises a near field telemetry module to wirelessly receive first information into the IMD, a far field telemetry module to wirelessly receive second information into the IMD, and a processor in electrical communication with the near field telemetry module and the far field telemetry module. The processor is configured to establish, in relation to a communication signal received by the near field telemetry module, a time period during which communication via the far field telemetry module is available, and operate the IMD according to the received second information upon receiving third information via the near field telemetry link.

Claims

1. An implantable medical device (IMD) including:

a near field telemetry module configured to wirelessly receive first information into the IMD;

a far field telemetry module configured to wirelessly receive second information into the IMD; and

a processor in electrical communication with the near field telemetry module and the far field telemetry module, wherein the processor is configured to;

establish, in response to the first information received by the near field telemetry module, a time period during which communication via the far field telemetry module is available; and

operate the IMD according to the received second information in response to receiving third information via the near field telemetry module.

2. The IMD of claim 1, wherein the second information includes at least one therapy parameter for operating the IMD.

3. The IMD of claim 1, wherein the second information includes instruction code for execution by the processor.

4. The IMD of claim 1, wherein the second information includes resynchronization information to synchronize a duty cycle of the far field telemetry module with a far field telemetry link of a second device.

5. The IMD of claim 1, wherein the first information to be received by the near field module includes a digital key.

6. The IMD of claim 1, wherein the third information to be received by the near field module includes an update command to trigger an operation of the IMD that uses the second information.

7. The IMD of claim 6, including a memory integral to or electrically coupled to the processor, wherein the processor is configured to:

store the second information in a first location of the memory upon receiving the second information, wherein the first location is allocated for temporary storage; and

transfer the second information from the first location of the memory to a second location of the memory after the near field module receives the update command, wherein the second location of the memory is allocated for storage of at least one of executable code and operating parameters.

8. The IMD of claim 1, wherein the far field telemetry nodule is configured to transmit fourth information via the far field telemetry link to a second device during the time period, wherein the fourth information includes diagnostic data generated by the IMD.

9. The IMD of claim 1, wherein the near field telemetry module is configured to receive information into the IMD during the time period when communication via the far field telemetry module of the IMD is available.

10. The IMD of claim 1,

wherein the first information to be received by the near field module includes a specified communication signal;

and

wherein the processor is configured to provide the time period during which communication via the far field telemetry module is available while the near field module continues to receive the specified communication signal.

11. A method of operating an implantable medical device (IMD), the method comprising:

receiving first information using a wireless near field telemetry link of the IMD;

establishing, in response to the received first information, a time period in the IMD when communication via a wireless far field telemetry link of the IMD is available;

receiving second information into the IMD via the far field telemetry link;

receiving third information using the near field telemetry link; and

operating the IMD according to the received second information in response to receiving the third information using the near field telemetry module.

12. The method of claim 11, wherein receiving the second information includes receiving at least one parameter for operating the IMD via the far field link.

13. The method of claim 11, wherein receiving the second information includes receiving instruction code via the far field link for execution by the IMD.

14. The method of claim 11, wherein receiving the second information includes receiving resynchronization information to synchronize a duty cycle of the far field telemetry link with a far field telemetry link of a second device.

15. The method of claim 11, wherein receiving the first information includes receiving a digital key using the near field telemetry link.

16. The method of claim 11, wherein receiving the third information includes receiving an update command via the near field telemetry link, wherein the update command triggers an operation of the IMD that uses the second information.

17. The method of claim 16, wherein the second information is transferred from a first temporary memory location of the IMD to a second executable memory location of the IMD after receiving the update command.

18. The method of claim 11, including transmitting fourth information via the far field telemetry link to a second device during the time period, wherein the fourth information includes diagnostic data generated by the IMD.

19. The method of claim 11, including receiving information into the IMD via the near field telemetry link during the time period when communication via a wireless far field telemetry link of the IMD is available.

20. The method of claim 11,

wherein receiving the first information includes receiving a digital key using the near field telemetry link;

and

wherein receiving the second information includes receiving the second information during the established time period when continuing to receive the digital key via the near field telemetry link.
