An implantable, bioresorbable vessel wall support, in particular a coronary stent, comprises a combination of metal materials which dissolves in the human body without any harmful effects on the person that wears the implant. The combination of metal materials can be an alloy or a local galvanic element.

An electrolytic capacitor, in particular a tantalum electrolytic capacitor, is provided with a metal anode, in particular a sintered tantalum anode (1), a non-conducting insulating layer applied on it by means of molding the metal anode (1) for forming the dielectric of the electrolytic capacitor, an electrolyte in liquid, pasty or solid form, which forms the cathode of the electrolytic capacitor, and a flat cathode contact (5, 17) for providing current to the electrolyte. The flat cathode contact (5, 7) is provided with an electrically conducting, fractal surface coating (6), at least in the area of its contact surface with the electrolyte.
