  • Implantatble identification marker
    Publication number: 20020083951
    Abstract: An implantable identification marker comprises an electronic device (4) enclosed within a vial (1; 2) isolating the device (4) from body fluids of the animal after insertion of the marker into the body of an animal. The marker further comprises a fixation structure (8; 5) providing a significantly in-creased total surface of the marker and/or a reduced specific weight of the marker. This improves the integration of the marker into the surrounding tissue avoiding migration within the animal.
