1. An implantable medical device comprising:
- a) hermetically sealed biocompatible housing;
b) an RFID microelectronics chip disposed within the housing;
c) an antenna wire having a first end portion electrically connected to a first end of the RFID chip inside the housing and extending along a length to a second end portion electronically connected to a second end of the RFID chip inside the housing with at least an intermediate portion of the length of the antenna wire between the first and second end portions residing outside the housing; and
d) a sealing material that hermetically seals against an outer surface of the first and second end portions of the antenna wire and against respective perimeter openings in the housing through which the antenna wire extends, wherein the intermediate portion of the antenna wire external to the housing serves as an antenna for the RFID microelectronics chip.

Abstract
A non-hermetically sealed and biocompatible multi-turn RFID loop antenna is electrically connected to a RFID chip which is enclosed within its own hermetically sealed miniature container. The hermetic seal can be very small and the loop antenna can be relatively large, wherein the entire package is both highly reliable, resistant to body fluids and completely biocompatible. The RFID structure can be implanted in a patient and later communicate with an RFID interrogator to provide information relating to the patient and/or implantable medical devices.
