Tactile feedback for indicating validity of communication link with an implantable medical device
First Claim
1. A communication device for establishing a communication link with an implantable medical communication device having a transceiver circuit, the device comprising:
- a first transceiver circuit coupled to an external communication device;
a hand-held communication head coupled to the first transceiver circuit to establish a communication link between the transceiver circuit and a second transceiver circuit coupled to the implantable medical device;
a tactile feedback generation device coupled to the communication head and providing a tactile response feedback in response to detection of a valid communication link between the first transceiver circuit and the second transceiver circuit; and
control circuitry operable to detect the valid communication link and upon detection of the valid communication link produce an activation signal;
wherein said tactile feedback generation device producing vibratory motion transmitted through the communication head in response to the activation signal, the vibratory motion produced being modified as a function of differing signal strengths between the first transceiver circuit and the second transceiver circuit and wherein the first transceiver comprises an automatic gain control amplification stage providing an adjustment in gain based on an inverse relationship to the signal strength between the first transceiver circuit and the second transceiver circuit, and wherein the control circuitry comprises an amplifier providing a drive signal to the tactile feedback generation device to modify the vibratory motion based upon the gain adjustment provided by the automatic gain control amplification stage.

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.
