Abstract

Embodiments of the invention provide methods, systems, and devices for enabling data communication between an IMD and a host computer. In one embodiment, a device is provided that comprises a frequency and protocol agile transceiver capable of communicating with an IMD via a first communications link and with a host computer via a second wireless communications link, wherein the first wireless communication link is configured for substantially shorter communication range than the second wireless communication link. An apparatus is provided according to another embodiment of the invention that comprises an interface between an IMD and a communications device, such as a wireless telephone or a two-way wireless pager. The interface can communicate directly with the IMD to retrieve clinical data stored in the IMD and can utilize the communications device to transmit the clinical data to a host computer.

Claims

1. An apparatus for enabling data communication between an implantable medical device and a host computer, comprising:

a frequency and protocol agile transceiver configured to communicate with the implantable medical device via a short range wireless communications link in a first state and to communicate with the host computer via a long range wireless communications link in a second state;

a central processing unit;

a memory; and

a program capable of executing on the central processing unit operative to periodically interrogate the implantable medical device for clinical data in the first state.

2. The apparatus of claim 1, wherein the program, while interrogating the implantable medical device, is configured to:

unlock the implantable medical device;

receive the clinical data stored in the implantable medical device via the short range wireless communications link;

determine whether clinical data is stored in the memory;

in response to determining that clinical data is stored in the memory;

establish the communications link with the host computer via the communications device; and

transmit the clinical data to the host computer.

3. The apparatus of claim 1, wherein the program is configured to:

configure the transceiver for communication with the implantable medical device using the short range wireless communications link,

receive clinical data from the implantable medical device using the short range wireless communications link, and

store the clinical data in the memory for delivery to the host computer using the long range wireless communications link.

4. The apparatus of claim 3, wherein the program is operative to:

configure the transceiver for communication with the host computer using the long range wireless communications link;

determine whether clinical data is stored in the memory; and

establish a data communications channel with the host computer using the long range wireless communications link and to transmit the clinical data to the host computer using the channel if clinical data is stored in the memory.

5. The apparatus of claim 4, wherein the program is operative to:

determine whether the clinical data was successfully transmitted to the host computer; and

remove the clinical data from the memory if the clinical data was successfully transmitted to the host computer.

6. The apparatus of claim 5, wherein the program is operative to transmit the clinical data to the host computer on a schedule coordinated with the host computer.

7. The apparatus of claim 3, wherein the program is operative to:

configure the transceiver for communication with the host computer using the long range wireless communications link;

determine whether the clinical data should be delivered to the host computer if the clinical data is stored in the memory; and

establish a data communications channel with the host computer using the long range wireless communications link and to transmit the clinical data to the host computer using the channel if clinical data should be delivered to the host computer.

8. A method comprising:

periodically configuring a frequency and protocol agile transceiver to communicate with an implantable medical device via a short range wireless communications link;

periodically interrogating the implantable medical device for clinical data using the frequency and protocol agile transceiver and the short range wireless communication link;

configuring the frequency and protocol agile transceiver to communicate with a host computer via a long range wireless communications link; and

communicating the clinical data to the host computer using the frequency and protocol agile transceiver and the long range communication link.

9. The method of claim 8, further comprising:

determining whether the clinical data should be delivered to the host computer at a particular time; and

transmitting the clinical data to the host computer using the long range communication link if clinical data should be delivered to the host computer at the particular time.

10. The method of claim 9, further comprising:

storing the clinical data for delivery if the clinical data should not be delivered to the host computer at the particular time.

11. The method of claim 10, further comprising:

transmitting the stored clinical data to the host computer using the second wireless communications link on a schedule coordinated with the host computer.

12. The method of claim 8, including:

storing a serial number corresponding to the implantable medical device; and

transmitting the serial number to the implantable medical device as part of an authentication procedure.

13. The method of claim 12, including utilizing one or more implantable medical device support files that describe protocols for communicating with a plurality of different types of implantable medical devices to communicate with the implantable medical device.

14. A system comprising:

an implantable medical device, capable of communicating data wirelessly;

a host computer, capable of storing and communicating data;

an apparatus, capable of communicating wirelessly with both the implantable medical device and the host computer, the apparatus comprising;

a transceiver configured to communicate with the implantable medical device via a short range wireless communications link in a first state and to communicate with the host computer via a long range wireless communications link in a second state;

a central processing unit;

a memory; and

a program capable of executing on the central processing unit operative to periodically interrogate the implantable medical device for clinical data in the first state.

15. The system of claim 14, wherein the apparatus is configured to:

store a serial number corresponding to the implantable medical device; and

transmit the serial number to the implantable medical device as part of an authentication procedure.

16. The system of claim 14, wherein the program is operable to store the clinical data in the memory for delivery to the host computer using the long range wireless communications link.

17. The system of claim 16, wherein the program is operative to:

reconfigure the transceiver from the first state to the second state;

determine whether the clinical data should be delivered to the host computer if the clinical data is stored in the memory;

establish a data communications channel with the host computer using the long range wireless communications link; and

to transmit the clinical data to the host computer using the channel if clinical data should be delivered to the host computer.

18. The system of claim 17, wherein the program is operative to:

determine whether the clinical data was successfully transmitted to the host computer; and

remove the clinical data from the memory if the clinical data was successfully transmitted to the host computer.

19. The system of claim 18, wherein the program is operative to:

transmit the clinical data to the host computer on a schedule coordinated with the host computer.

20. The system of claim 18, wherein the apparatus includes a cellular phone.
