First Claim
Patent Images
1. An implantable medical device, comprising:
- a) 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
An implantable radio frequency identification (RFID) tag includes a hermetically sealed biocompatible housing for an active implantable medical device (AIMD), an RFID microelectronics chip is disposed within the housing, and a biocompatible antenna extends from the RFID microelectronic chip and exteriorly of the housing. In a preferred form of the invention, the antenna is disposed within a header block of the AIMD, and the RFID chip is disposed within the AIMD housing.
