The invention relates to a device, in particular for medical use as an endoprosthesis, preferably as an intraluminal endoprosthesis, having a base body (1, 1′), comprising at least partially a metallic material, and having a function element (3, 3′) that is attached to the base body and has a different metallic material composition in comparison with the material of the base body (1, 1′) in at least a portion of its volume, preferably having at least partially radiopaque and/or radiologically opaque material. To reduce direct metal contact between the base body (1,1′) and the function element (3, 3′) in the area where the base body (1, 1′) and the function element (3, 3′) are adjacent to one another, a first layer (5, 5′) is applied to and/or introduced into the borderline area (9, 9′) between the base body (1, 1′) and the function element (3, 3′), extending to the surface, such that said first layer is produced by plasma-chemical treatment in an aqueous solution containing phosphate ions, or comprises magnesium stearate. Furthermore, a method for producing such a device is proposed.
A device, which may be used as an endoprosthesis, optionally as an intraluminal endoprosthesis, having a base body comprising at least partially a metallic material, and having a function element attached to the base body and having a different metallic material composition in comparison with the material of the base body in at least a portion of its volume, optionally having at least partially radiopaque and/or radiologically opaque material, characterized in that a first layer is applied to and/or introduced into the borderline area between the base body and the function element, extending to the surface, such that said first layer
