Electrode line or electrode portion of an electrode line

摘要

An elongate implantable electrical line including an end component at one longitudinal end of the electrical line, wherein the end component includes at least one electrically conductive electrode surface electrically connected to the electrical line. The end component is a composite component that includes at least one thin metal layer with a layer thickness less than 1 μm. The at least one thin metal layer is applied to electrically insulating material of the composite component and is conductively connected to the electrical line, such that the at least one thin metal layer includes, or acts as, an electrode surface. The at least one thin metal layer includes an outer surface and is completely covered completely by at least one outer ceramic layer on the outer surface, such that the at least one thin metal layer is electrically insulated from a surrounding environment.

1. An elongate implantable electrical line comprising:
an end component at a first longitudinal end of the elongate implantable electrical line, wherein the end component comprises
at least one electrically conductive electrode surface electrically connected to the elongate implantable electrical line, and,a composite component that comprises
an electrically insulating main body comprising
a metal main body and,an inner insulating layer applied to the metal main body;at least one outer ceramic layer;at least one thin metal layer with an outer surface, and a layer thickness of less than 1 μm, which is coupled to the electrically insulating main body;wherein the at least one thin metal layer is conductively connected to the electrical line;wherein the at least one thin metal layer is applied to the electrically insulating main body; and,wherein the at least one thin metal layer is covered on said outer surface by the at least one outer ceramic layer, such that said at least one thin metal layer is between said electrically insulating main body and said at least one outer ceramic layer, wherein the at least one thin metal layer forms the at least one electrically conductive electrode surface, and wherein the at least one thin metal layer is electrically insulated by the at least one outer ceramic layer such that the at least one thin metal layer is configured to be electrically insulated from an environment surrounding the composite component.
