Abstract: An installation tool set for producing an implantable medical device includes an installation tool with a rod longitudinal axis and an axially extending rod surface, along which a local recess is introduced. A fixing body defines a through channel, through which the installation tool is passable along a first rod section and into which an opening opens. The opening is oriented orthogonally to the through channel, around which an internal thread is arranged within the fixing body. An adjusting rod has a joining contour that is counter-contoured relative to the local recess in the installation tool and a counter-thread engageable with the internal thread of the fixing body. A receiving structure defines a recess into which the installation tool is inserted. The fixing body, an electrically conductive contact ring, and an electrically insulating, elastically deformable seal ring are arranged coaxially and in axially serial sequence along the installation tool.

Abstract: An implantable electrical contact arrangement has at least one electrode element arrangement enclosed entirely by biocompatible, electrically insulating material, and an electrode surface that is directly or indirectly enclosed by the biocompatible, electrically insulating material, the electrode element arrangement having a stack-shaped layer composite which has a metallization layer at least on a ceramic substrate over an adhesion promoter layer. The layer composite is bonded to a passivation layer such that covalent bonds are formed, and is otherwise completely encased by the passivation layer, except for at least one surface area of a metallization layer facing away from the layer composite. The passivation layer has a surface facing away from the layer composite and to which the biocompatible, electrically insulating material is directly or indirectly adjacent.

Abstract: A medical implant forms a sleeve for arranging about a nerve fiber bundle. The sleeve has a film-like substrate with a first section that converts into a hollow-cylindrical shape. A first end of the first section rests against a first surface of the first section in the wound state. The first surface faces an area enclosed by the wound first section. A second end lies opposite the first end and in the wound state is arranged laterally to a second surface of the first section. The second surface faces away from the first surface and from the radially enclosed area. An area of the first section end is monolithically connected with a second section, which in the wound state is adjacent to the second surface of the first section. The first and second sections have the set shape, with a winding direction oriented oppositely relative to the first end.
