RFID DETECTION AND IDENTIFICATION SYSTEM INCLUDING AN RFID READER HAVING A LIMITED TRANSMIT TIME AND A TIME-OUT PERIOD TO PROTECT A MEDICAL DEVICE AGAINST RFID-ASSOCIATED ELECTROMAGNETIC INTERFERENCE

摘要

A system is provided for identifying implanted medical devices, leads and systems, as well as objects in close proximity to a patient having an implanted active medical device, using a radio frequency identification (RFID) tag having retrievable information relating to the AIMD, lead system and/or patient. An RFID tag communicator includes a circuit for limiting the total continuous transmit time of an interrogation signal, and a time-out circuit for delaying a second and any subsequent interrogation of the RFID tag.
