Abstract

A system and method for repeating radio frequency (RF) transmissions between a programmer and an implantable medical device (IMD) is provided. One aspect of this disclosure relates to an RF repeater. According to various embodiments, the repeater includes a first antenna and a first communication circuit electrically connected to the first antenna. The first communication circuit is adapted to communicate with an IMD, the IMD including a built-in active telemetry transceiver, over a first channel. The device also includes a second antenna and a second communication circuit electrically connected to the second antenna. The second communication circuit is adapted to communicate with a programmer over a second channel different from the first channel. The device also includes a control circuit coupled to the first and second communication circuits. The control circuit is adapted to enable or disable the first and second communication circuits. Other aspects and embodiments are provided herein.

Claims

1. A method, comprising:

receiving a radio frequency communication between an implantable medical device (IMD) and a programmer over a first channel; and

transmitting the radio frequency communication over a second channel different from the first channel to improve transmission quality and reduce potential for lost or interrupted communication.

2. The method of claim 1, wherein receiving a radio frequency communication includes receiving the radio frequency communication at a first frequency.

3. The method of claim 2, wherein transmitting the radio frequency communication includes transmitting the radio frequency communication at a second frequency different from the first frequency.

4. The method of claim 1, wherein transmitting the radio frequency communication includes transmitting the radio frequency communication from a higher elevation than either the IMD or the programmer.

5. The method of claim 1, wherein transmitting the radio frequency communication includes transmitting the radio frequency communication at an amplitude sufficient to improve transmission quality and reduce potential for lost or interrupted communication compared to direct communication between the IMD and the programmer.

6. The method of claim 1, further comprising:

forwarding data received in the radio frequency communication to a monitoring station.

7. The method of claim 6, wherein forwarding data received in the radio frequency communication to a monitoring station includes forwarding data to a website.

8. The method of claim 6, wherein forwarding data received in the radio frequency communication to a monitoring station includes forwarding data to a local area network.

9. The method of claim 1, wherein receiving a radio frequency communication includes using the programmer to control the receiving.

10. The method of claim 1, wherein transmitting the radio frequency communication includes using the programmer to control the transmitting.

11. A method for using a radio frequency telemetry repeater having a first communication circuit and a second communication circuit, the method comprising:

receiving a first radio frequency communication from an implantable medical device (IMD) over a first channel using the first communication circuit;

transmitting the first radio frequency communication to a programmer over a second channel different from the first channel using the second communication circuit.

receiving a second radio frequency communication from the programmer using the second communication circuit; and

transmitting the second radio frequency communication to the IMD using the first communication circuit.

12. The method of claim 11, further comprising determining when the programmer is sending data to the IMD or receiving data from the IMD.

13. The method of claim 12, further comprising, upon determining that the programmer is sending data to the IMD, enabling the second communication circuit to receive and the first communication circuit to transmit.

14. The method of claim 12, further comprising, upon determining that the programmer is not sending data to the IMD, enabling the first communication circuit to receive and the second communication circuit to transmit.

15. The method of claim 11, wherein transmitting the first radio frequency communication includes increasing signal strength of the received first communication.

16. The method of claim 11, wherein transmitting the second radio frequency communication includes increasing signal strength of the received second communication.

17. The method of claim 11, wherein receiving and transmitting using the first communication circuit includes using a first transceiver.

18. The method of claim 11, wherein receiving and transmitting using the first communication circuit includes using a first transmitter and a first receiver.

19. The method of claim 11, wherein receiving and transmitting using the second communication circuit includes receiving using a second transceiver.

20. The method of claim 11, wherein receiving and transmitting using the second communication circuit includes using a second transmitter and a second receiver.
