Patent ID: 8060214

Claim:
A system for communicating with a medical device implanted in a vessel of a human body, the system comprising: an implantable medical device (IMD); an inductive coil electrically coupled to the implantable medical device; the inductive coil configured to expand from a collapsed position, capable of delivery through the vessel, to an expanded position within the vessel, the inductive coil configured to frictionally engage a wall of the vessel and secure the implantable medical device within the vessel in the expanded position; the implantable medical device comprising a physiologic sensor device including a physiologic sensor, a casing having a number of feedthroughs electrically coupling the implantable medical device to the inductive coil, a rechargeable power source, a recharge controller configured for controlling recharging of the power source, communication circuitry operable to transmit and receive data via the inductive coil, and a sensor device controller configured for controlling data transmission and data reception by the communication circuitry; wherein electromotive force (EMF) is induced in the inductive coil when an oscillating electromagnetic field is created near the inductive coil; and wherein the sensor device controller is configured to detect a command from a manager device in communication with the IMD to enter a recharge mode of operation and to responsively deactivate at least data transmission by the communication circuitry via the inductive coil during the recharge mode of operation.
