RFID detection and identification system for implantable medical lead systems
First Claim
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.

Abstract
A system for identifying active implantable medical devices (AIMD) and lead systems implanted in a patient using a radio frequency identification (RFID) tag having retrievable information relating to the AIMD, lead system and/or patient. The RFID tag may store information about the AIMD manufacturer, model number, serial number; leadwire system placement information and manufacturer information; MRI compatibility due to the incorporation of bandstop filters; patient information, and physician and/or hospital information and other relevant information. The RFID tag may be affixed or disposed within the AIMD or leadwires of the lead system, or surgically implanted within a patient adjacent to the AIMD or leadwire system.
