Abstract

A passive communication scheme between one or more external instruments communicable with one or more implanted medical devices (IMDs) provides a system to collect data from the IMDs. Further, the one or more programmers are communicable with a remote central server or a network where the collected data is stored. The one or more external instruments exchange data by passively interrogating each other and any proximate IMD or IMDs. Specifically, the external instruments may be represented by a programmer type device. The programmer is enabled to interrogate and exchange data with one or more IMDs in one or more patients when they come within telemetry or wireless communication range. Similarly, two or more programmers interrogate and exchange data with each other when placed within a telemetry or wireless communication range. Further, data collected by the programmer or programmers is transferred to a central location using network and equivalent data transmission medium.

Claims

1. A data exchange and transmission system wherein one or more external instruments communicate with each other and with one or more implantable medical devices (IMDs), the system comprising:

at least two programmers;

at least one IMD; and

a wireless communication between said at least two programmers and said at least one IMD;

said wireless communication upon activation enabling said at least one programmer to passively collect data or transmit data between said at least two programmers and said at least one IMD.

2. The system of claim 1 further comprising a network of one or more programmers adapted to passively interrogate and exchange data between themselves.

3. The system of claim 2 wherein said network of one or more programmers passively interrogates said one or more IMDs.

4. The system of claim 1 wherein said at least two programmers includes a sleep mode that enables communication between said at least two programmers.

5. The system of claim 1 wherein said data is ultimately transferred to a server.

6. A communication scheme between at least two programmers to passively exchange data gathered from one or more IMDs, the communication scheme comprising:

the at least two programmers;

a wireless communication scheme; and

means for passively activating the at least two programmers to exchange the data via said wireless communication.

7. The communication scheme of claim 6 wherein the at least two programmers include a sleep mode wherein sufficient power to sustain said wireless communication means is maintained.

8. The communication scheme of claim 6 wherein said means for passively activating includes a continuous interrogation means between the devices to transfer the data therebetween.

9. The communication scheme of claim 6 wherein said wireless communication means includes a one of telemetry, laser and Blue Tooth.

10. The communication scheme of claim 6 wherein said at lest two programmers interrogate and exchange said data therebetween contemporaneous with acquisition of additional data from said one or more IMDs.

11. The communication scheme of claim 6 wherein said at least two programmers interrogate one another to gather data from each other wherein one of said at least two programmer is misplaced and its location is unknown.

12. The communication scheme of claim 6 wherein said data resident in said at least two programmers is transmitted to a server.

13. A method of gathering data from one or more IMDs, using a passive interrogation scheme implemented in at least one programmer, the method comprising:

providing the one or more IMDs;

providing the at least one programmer, and

enabling a passive wireless communication between said one or more IMDs and the at least one programmer;

wherein said at least one programmer is provided with a sleep mode power source to continuously and passively interrogate the one or more IMDs and one or more programmers within a range of said wireless communication.

14. The method of claim 13 wherein a plurality of programmers exchange data via said passive wireless communication.

15. The method of claim 13, further comprising providing a plurality of additional programmers and exchanging data between said plurality of additional programmers via passive wireless communication.

16. The method of claim 13 wherein said at least one programmer is implanted to update software resident in said one or more IMDs after precisely checking a resident software in said one or more IMDs.

17. The method of claim 13, further comprising providing a network of programmers and wherein said at least one programmer communicates with said network of programmers.

18. The method of claim 13, wherein said at least one programmer communicates with one or more nomad programmers encountered at random.

19. The method of claim 13, wherein said at least one programmer communicates with one or more nomad IMDs encountered at random.
