Abstract

The invention is directed to a programmer for communication with different medical devices that utilize different telemetry communication techniques. The programmer receives telemetry signals from a given medical device, and selects an appropriate communication mode, which can be pre-programmed into the programmer as one of a plurality of possible communication modes. The programmer can configure itself for communication with a given medical device based on the telemetry signal it receives.

generate a second signal that complies with the selected communication mode; and

send the second signal to the medical device.

13. The programmer of claim 12, wherein the second signal requests information from the medical device, wherein the control unit receives requested information from the medical device in response to the second signal.

14. The programmer of claim 10, the control unit being configured to:

receive input specifying a therapy;

generate a second signal that complies with the selected communication mode to program the medical device to implement the therapy; and

send the second signal to the medical device.

15. The programmer of claim 10, wherein the memory stores a lookup table that maps numbers associated with the plurality of possible communication modes to numbers associated with a set of signatures, and wherein the control unit selects the communication mode from a plurality of possible communication modes based on the first signal by:

accessing the lookup table;

identifying a signature that substantially correlates to the first signal; and

selecting the communication mode based on the identified signature using the lookup table.

16. The programmer of claim 15, wherein the control unit configures for communication with the medial device in compliance with the selected communication mode.

17. The programmer of claim 10, the control unit being configured to initiate telemetry to cause the medical device to send the first signal.

18. The programmer of claim 17, wherein the control unit initiates telemetry by performing a plurality of possible telemetry initiation techniques.

19. The programmer of claim 10, wherein the programmer forms at least part of an apparatus selected from the following group:

a wrist watch, a belt, a necklace, a piece of jewelry, an adhesive patch, a pager, a key fob, and identification card, a laptop computer, an interrogator, and a hand-held computer.

20. The programmer of claim 10, wherein the memory comprises a removable memory card.

21. The programmer of claim 10, further comprising a patient activator to allow the a patient to activate the programmer.

22. The programmer of claim 10, further comprising a feedback device to indicate to a patient that telemetric communication has been initiated.

23. A computer-readable medium comprising instructions that cause a medical device programmer to select a communication mode from a plurality of possible communication modes based on a first signal received from a medical device.

24. The computer-readable medium of claim 23, further comprising instructions that cause the medical device programmer to select the communication mode based on the first signal by:
