IMPLANTABLE MINIATURE TRANSPONDER AND METHOD FOR THE PRODUCTION THEREOF
First Claim
1. Method of assembling an implantable miniature transponder comprisingan elongate tubular plastic enclosure havinga hollow interior enclosed by a generally cylindrical wall, defining a longitudinal axis,a first end of the cylindrical wall defining a first circular open mouth and =a second end opposite to the first end, anda transponder unit havingan antenna andan integrated circuit, electrically connected to the antenna and so designed that in response to received transmitted energy obtained from the antenna, a response signal which is retransmitted to and through the antenna is generated,the method comprising the steps of:
- inserting said transponder unit within the hollow interior of said enclosure,externally touching the first end with a forming tool, andcompletely closing the first end by reducing the width of the first mouth by means of deforming the first end inwards with the forming tool until the first mouth is totally closed.

Abstract
The invention relates to a method of assembling an implantable miniature transponder (1) comprising an elongate tubular plastic enclosure (2) having a first end (6) of a cylindrical wall (4) defining a first circular open mouth (7), and a transponder unit (11). The method comprises the steps of inserting said transponder unit (11) into the enclosure (2), externally touching the first end (6), in particular being exposed to heat, with a forming tool (21a; 21b), and completely closing the first end (6) by reducing the width of the first mouth (7) by means of deforming the first end (6) inwards with the forming tool (21a; 21b) until the first mouth (7) is totally closed. In a further embodiment, a relative rotation between the enclosure (2) and the forming tool (21a; 21b) is caused. Further, the invention relates to a transponder (1) with a completely closed plastic enclosure (2), having a closed first end (6) and a closed second end (8), being a single thermoplastic piece.

27. Implantable miniature transponder comprising
an elongate tubular plastic enclosure having a hollow interior enclosed by a generally cylindrical wall, a first end of the cylindrical wall and a second end opposite of the first end, wherein both the first end and the second end are completely closed, and a transponder unit within the hollow interior and completely enclosed within the enclosure, having an antenna and an integrated circuit, electrically connected to the antenna and so designed that in response to received transmitted energy obtained from the antenna, a response signal which is retransmitted to and through the antenna is generated, wherein the elongated tubular plastic enclosure comprising the cylindrical wall, the closed first end and the closed second end is a single thermoplastic piece.
