1. A stimulation electrode, comprising:
- an electrode base body which has a basic geometric shape and a surface area; and
a porous surface coating which is provided on at least a portion of the electrode base body, which is comprised of an inert material having a low oxidation tendency effective to render the material substantially inert and being selected from the group consisting of a element, a chemical compound, and an alloy, which is porous and has a fractal spatial geometry, and which has an active surface area which is greater by a factor of at least one thousand times than the surface area of the electrode base body.

Abstract
A stimulation electrode having a porous surface coating whose active surface area is significantly greater than the surface area defined by the geometric shape of the electrode, wherein the surface coating comprises an inert material, i.e. a material having no or only a very slight oxidation tendency, wherein the material of the surface coating is formed from an inert element, an inert chemical compound and/or an inert alloy, and the active surface area, by virtue of its fractal-like geometry, is greater by a factor of at least one thousand than the surface area defined by the basic geometric shape of the electrode.

7. A stimulation electrode, comprising:
-
an electrode base body which has a basic geometric shape and a surface area; and a porous surface coating which is a thin film applied to the electrode by a thin-layer technology process, which is provided on at least a portion of the electrode base body, which is comprised of an inert material having a low oxidation tendency effective to render the material substantially inert and being selected from the group consisting of a element, a chemical compound, and an alloy, which is porous and has a fractal spatial geometry, and which has an active surface area which is greater by a factor of at least one thousand times than the surface area of the electrode base body. - View Dependent Claims (8)
