  • System and method of bridging a transreceiver coil of an implantable medical device during non-communication periods
    Patent number: 6510345
    Abstract: The present invention discloses a method of and a system for preventing unwanted alternating current magnetic fields transmitted from an external source from disrupting electrical circuitry within an implantable medical device, while permitting desired communications between the implantable medical device and a programmer detected in proximity to the implantable medical device. The implantable medical device is capable of communication with at least one implantable lead position within a heart of a patient. The method includes activating an electrical device to create a short circuit in parallel with an inductive transreceiver coil of the implantable medical device, thereby shorting out the inductor transreceiver coil. In this mode, alternating current magnetic fields do not effect electrical circuitry within the implantable medical device. The method further includes detecting a direct current magnetic field indicating the presence of a programmer located in proximity to the implantable medical device.
