1. An apparatus for insertion or implantation into a living body comprising:
- a marker element made of an X-ray visible material which is inserted into a cutout in an implant structure, the cutout having expansions on both of its opening sides so that a conical shape of an exterior side of the implant structure lies adjacent to a conical expansion of an interior side of the implant structure to form a double cone, wherein the marker element is pressed or riveted into the cutout.

Abstract
A bodily implant, in particular a stent, for insertion or implantation into a living body, having a marker element made of an X-ray visible material which is inserted into a cutout in an implant structure is disclosed. The cutout has expansions on both of its opening sides, and the marker element is pressed or riveted into the cutout so that a positive fit is formed between the marker element and the implant structure.

7. A method for increasing or enabling the X-ray visibility of a bodily implant, the method comprising:
-
forming a cutout in an implant structure by means of a laser so that the cutout assumes a conical shape on an exterior side of an implant structure;
providing a conical expansion of an interior side of the implant structure so that the conical shape lies adjacent to the conical expansion to form a double cone;
inserting an essentially cylindrical marker element into the cutout; and
pressing the marker element. - View Dependent Claims (8, 9)

10. A method for manufacturing a bodily implant having an X-ray visible marker element, the method comprising:
-
forming a cutout in an implant structure;
expanding the cutout outwardly on both opening sides so that a conical shape on an exterior side of the implant structure lies adjacent to a conical expansion of an interior side of the implant structure to form a double cone; and
pressing or riveting in the marker element. - View Dependent Claims (11, 12)
