1. A process for identifying a leadwire system implanted within a patient, comprising the steps of:

  • a) providing a leadwire system comprising a leadwire having a length extending from a proximal end that is electrically connectable to an active implantable medical device (AIMD) to a distal end electrically connected to an electrode, wherein a bandstop filter is electrically connected in series with the leadwire somewhere along the length thereof;

    b) attaching a radio frequency identification (RFID) tag to the leadwire system, the RFID tag having retrievable information relating to the leadwire system;

    c) interrogating the RFID tag; and

    d) retrieving information from the RFID tag relating to the magnetic resonance imaging MRI compatibility of the leadwire system under at least one of a static magnetic field and the ability of the bandstop filter to attenuate current flow through the leadwire system at one or more selected frequencies or ranges of frequencies.
