Abstract

Implantable medical device telemetry is provided between an implantable medical device and an external communication device. The implantable medical device includes a device transmitter and/or a device receiver. The external communication device includes a moveable communication head including an antenna therein connected to at least one of an external transmitter and/or an external receiver for communication with the device transmitter and/or the device receiver of the implantable medical device. A user moves the moveable head apparatus relative to the implantable medical device. Tactile feedback is provided to the user via the moveable head apparatus upon movement of the moveable head apparatus to a position where valid telemetry can be performed.

Claims

1. A device comprising:

an antenna;

at least one of a transmitter and a receiver connected to the antenna for communication with an implantable medical device;

a tactile feedback device configured to provide a tactile indication as a function of a strength of a signal communicated between the device and the implantable medical device, wherein the tactile feedback device is configured to activate the tactile indication upon determining that the strength of the signal is greater than a reference strength and deactivate the tactile indication after a predetermined period of time.

2. The device of claim 1, wherein the tactile feedback device is configured to reactivate the tactile indication when the strength of the signal falls below valid communication link becomes invalid following discontinuation of the tactile indication.

3. The device of claim 1, further comprising:

a controller apparatus; and

a communication head electrically coupled to the controller apparatus, wherein the tactile feedback device provides the tactile indication to a user via the communication head.

4. The device of claim 1, wherein the tactile feedback device controls a frequency of vibration of the tactile indication as a function of the strength of the communicated signal.

5. The device of claim 4, wherein the tactile feedback device increases the frequency of vibration as the signal strength increases and decreases the frequency of vibration of the tactile feedback as the signal strength decreases.

6. The device of claim 1, wherein the external communication device includes a programming apparatus for the implantable medical device.

7. The device of claim 1, wherein the external communication device includes a patient activation apparatus for the implantable medical device.

8. The device of claim 1, further comprising a non-tactile position indicator used in conjunction with the tactile feedback device.

9. A device comprising:

means for communicating with an implantable medical device;

means for providing a tactile indication as a function of a strength of a signal communicated between the device and the implantable medical device, wherein the means for providing the tactile indication activate the tactile indication upon determining that the strength of the signal is greater than a reference strength and deactivate the tactile indication after a predetermined period of time.

10. The device of claim 9, wherein the means for providing the tactile indication reactivate the tactile indication when the strength of the signal falls below valid communication link becomes invalid following discontinuation of the tactile indication.

11. The device of claim 9, further comprising:

a controller apparatus; and

a communication head electrically coupled to the controller apparatus, wherein the means for providing the tactile indication provide the tactile indication to a user via the communication head.

12. The device of claim 9, wherein the means for providing the tactile indication control a frequency of vibration of the tactile indication as a function of the strength of the communicated signal.

13. The device of claim 12, wherein the means for providing the tactile indication increase the frequency of vibration as the signal strength increases and decrease the frequency of vibration of the tactile feedback as the signal strength decreases.

14. The device of claim 9, further comprising means for providing a non-tactile position indicator for use in conjunction with the means for providing the tactile indication.

15. A device comprising:

an antenna;

at least one of a transmitter and a receiver connected to the antenna for communication with an implantable medical device;

a tactile feedback device configured to provide a tactile indication as a function of a strength of a signal communicated between the device and the implantable medical device, wherein the tactile feedback device controls a frequency of vibration of the tactile indication as a function of the strength of the communicated signal.

16. The device of claim 15, wherein the tactile feedback device increases the frequency of vibration as the signal strength increases and decreases the frequency of vibration of the tactile feedback as the signal strength decreases.
