Abstract: The invention relates to a multi-layer structure having at least one flexible backing layer, at least one electrically insulating layer, and at least one electrically conductive layer, the electrically insulating layer being arranged between and connected to the backing layer and the electrically conductive layer, at least the backing layer being able to be elongated by at least 0.5% and comprising a shape memory material that is adapted to transmit restoring forces to mend cracks in the electrically insulating layer.

Abstract: A medical device with structure elements is made by providing a substrate; optionally depositing a layer of a sacrificial material on the substrate; and applying of a photoresist layer to the substrate. The layer of sacrificial material and structuring of the photoresist layer according to the shape of the structure elements are produced such that first free spaces are formed which are open on the side facing away from the substrate and are delimited by side faces of the photoresist layer. An angle is set between the side faces and the substrate. Sacrificial material is deposited in the first free spaces so first mask elements from sacrificial material are adapted to the inner contour of the first free spaces. The photoresist layer is removed so that second free spaces are formed between the first mask elements.

Abstract: A method for producing a medical device with a lattice structure, connected at least in some areas to a cover. The lattice structure is arranged on a substrate via the side to be connected to the cover, the lattice structure has the side arranged on the substrate pressed at least partially into the substrate, the lattice structure is coated with a first layer of a sacrificial material. At least some of the interstices of the lattice structure are covered by the first layer, and the first layer with the lattice structure on the side to be connected to the cover forms a substantially closed surface, the substrate is removed, making the side of the lattice structure accessible for connection to the cover. A second layer for forming the cover is applied to the side of the lattice structure previously pressed into the substrate, and the sacrificial material is removed.

Abstract: A method for producing a medical functional element having a self-supporting lattice structure which has interconnected webs. The method applies a first layer to the substrate layer, the first layer is structured by an etching process, the structured first layer is under-cut of a wet chemical etching process acting on the substrate layer, the substrate layer is removed in order to form the self-supporting lattice structure, a web constructional layer is applied to the first layer. The method is distinguished by the forming the first web attachment layer which has a smaller layer thickness than the web constructional layer and is intimately bonded to the web constructional layer in such a way that the web attachment layer, together with the web constructional layer, forms the webs of the self-supporting lattice structure.
