Abstract: An apparatus and method for adjusting an injection device for administering a substance that includes a device housing with an array of fastening points. The apparatus has at least two housing-like shells, each having at least one holding device and at least one blocking device for attaching to the housing. The holding device of a first shell can be attached to a fastening point, and the holding device of a second shell can be attached to a further fastening point. Upon attaching all of the plurality of housing-like shells to the housing, the blocking devices of the plurality of housing-like shells prevent the disengagement of the plurality of housing-like shells from the housing by blocking detachment of the holding devices from the fastening points. At least one of the housing-like shells comprises an electronic assembly and shell attachment to the housing activates the electronic assembly.

Abstract: An adjustable injection device for administering a substance includes a housing with an array of fastening points and at least two housing-like shells, each having at least one holding device and at least one blocking device for attaching to the housing. The holding device of a first shell can be attached to a fastening point, and the holding device of a second shell can be attached to a further fastening point. The holding device of the first shell is prevented from disengagement therefrom by the blocking device of the second shell, and the holding device of the second shell is prevented from disengagement therefrom by a blocking device of a further shell, or, in the event that the injection device has only two shells, is prevented from disengagement from the further fastening point by a blocking device of the first shell whereby the shells are non-detachably connected to the housing.

Abstract: The coating is particularly suited for identifying and characterizing surgical implants and instruments as well as for providing a diffusion barrier for surgical implants and instruments. The coating comprises a biocompatible, transparent and, in itself, colorless interference layer, which is joined to the surface of the implant or of the instrument, has a constant layer thickness, and which is not, or only slightly, electrically conductive, i.e., is dielectric. The coating is also suited for generating interferences and interference colors over the entire visible spectrum.

Abstract: A bioactive surface layer that is particularly suited for medical implants and prostheses. A variable portion of the 0.1 to 50.0 ?m thick, porous surface layer includes calcium phosphate phases. The surface layer contains amorphous or nanocrystalline calcium phosphates and the pore density on the surface of the surface layer ranges from 104 to 108 pores/mm2. The ratio of Ca/P over the entire surface layer ranges from 0.5 to 2.0. The surface layer has a high solubility so that it can act as a contributor of calcium phosphate for the formation of bone.
