Abstract: A method for producing x-ray markers. During the process, a predetermined breaking point is severed in order to detach x-ray markers from part of a material layer. There is also described an x-ray marker, a medical implant, and a semifinished product.

Abstract: A method produces a marker element, which is composed of two radiopaque layers and an interposed adhesive layer. The marker element is heated and joined into the eyelet of a stent. The introduction of the mechanical force causes the two layers of the marker element to be compressed, whereby the available volume is reduced for the softened adhesive of the adhesive layer. Consequently, the softened adhesive from the adhesive layer is pushed out of the side of the marker element, so that the adhesive flows into the empty volume of the adhesive gap between the marker element and the inner edge of the eyelet of the scaffold and bonds to the inner edge of the eyelet.

Abstract: Packaging has an outer sleeve, which surrounds an interior space for receiving an object, such as a sterilized medical implant. A separate container is arranged in the interior space and surrounds an absorber in a gas-tight manner, such that a gas present in the interior space cannot pass to the absorber. The container is configured to be opened by the application of force when the outer sleeve is closed, such that a gas disposed in the interior space can pass to the absorber and can be absorbed thereby. In preferred embodiments, the absorber absorbs air with the reactive constituents O2 and/or H2O. Depending on the application, however, other gases can also be absorbed by the absorber. A method for packaging is also provided.

Abstract: An actuator having a housing, a connecting element, a shape memory element which changes shape when heated, a heating element and a heat conducting element. The shape memory element is configured in substantially elongate form and is arranged in the housing such that it displaces the connecting element when it changes shape. The heating element, when activated, heats the shape memory element. The heat conducting element is in contact with the shape memory element at least some of the time, at a contact surface which is larger than 0.1 times the total surface of the shape memory element. While in contact with the shape memory element, the heat conducting element bears at least partially displaceably against the latter and has a free surface which is not in contact with either the shape memory element or the heating element that is at least 1.6 times larger than its contact surface.
