Abstract: A method for connecting an X-ray marker to a medical implant includes providing a medical implant having an opening for receiving the X-ray marker. An X-ray marker is provided. The X-ray marker is glued into the opening with a liquid adhesive that includes at least one first component including a fibrinogen.

Abstract: A tool for processing an inner surface of a seamlessly drawn tube is sized and configured to be inserted into the interior of the tube. The tool has an outer side defining multiple flow channels in the form of grooves arranged adjacently to each other in a circumferential direction of the tool, wherein each groove on the outer side forms a cutting edge and preferably at least two cutting edges. The tool is moved along a longitudinal axis (x) of the tube while simultaneously rotating the tool in the circumferential direction (U) of the tool by applying a gaseous medium (G) to the tool and/or by acting on the tool with an alternating magnetic field to remove contaminations of the tube which protrude from the inner surface.

Abstract: A marker element for an implant is made from a planar or hollow body-shaped semi-finished product. The semi-finished product is subjected to a plasma-electrolytic treatment on one side, so that a marker element with a surface that is porous on one side is produced.
