| 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 ( 21 a ; 21 b ), 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 ( 21 a ; 21 b ) until the first mouth ( 7 ) is totally closed. In a further embodiment, a relative rotation between the enclosure ( 2 ) and the forming tool ( 21 a ; 21 b ) 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. |
