The passivated product comprises a raw product and a passivation coating. The raw product is made at least partially of an alloy comprising Cr, Ni, Mo and Co, preferably with tightly controlled levels of impurities. The method for manufacturing the passivated product comprises a providing of a raw product and a passivating of a surface of the raw product at least partially to provide a passivated product with a passivation coating. The raw product is made at least partially of an alloy comprising the following alloy components:＜br /＞ a) Cr in the range from about 10 to about 30 wt. %;＜br /＞ b) Ni in the range from about 20 to about 50 wt. %;＜br /＞ c) Mo in the range from about 2 to about 20 wt. %;＜br /＞ d) Co in the range from about 10 to about 50 wt. %.The A1 content of the Cr, Ni, Mo and Co alloy is less than about 0.01 wt. % and each wt. % is based on the total weight of the alloy. ＜img id="iaf01" file="imgaf001.tif" wi="26" he="93" img-content="drawing" img-format="tif" /＞

[Heiko Specht] DE Hanau One aspect relates to an electrical bushing for use in a housing of an implantable medical device. The electrical bushing includes at least one electrically insulating base body and at least one electrical conducting element. The electrical bushing includes a holding element to hold the electrical bushing in or on the housing. The conducting element is set-up to establish, through the base body, at least one electrically conductive connection between an internal space of the housing and an external space. The conducting element is hermetically sealed with respect to the base body. The at least one conducting element includes at least one cermet. The holding element is made, to at least 80% by weight with respect to the holding element, from a material selected from the group consisting of a metal from any of the subgroups IV, V, VI, VIII, IX, and X of the periodic system.

[René RICHTER, Jörg-Martin GEBERT, Heiko SPECHT, Francis E. SCZERZENIE, Radhakrishnan M. MANJERI, Weimin YIN, Sai Srikanth GOLAGANI VENKATA KANAKA, Larry LARK] DE Hanau One aspect relates to a coil comprising at least two composite wires. The composite wire includes a first part and a second part. The first part is a metallic component. The second part includes an alloy of: a) Cr in the range from about 10 to about 30 wt. %; b) Ni in the range from about 20 to about 50 wt. %; c) Mo in the range from about 2 to about 20 wt. %; d) Co in the range from about 10 to about 50 wt. %. The Al content of the Cr, Ni, Mo and Co alloy is less than about 0.01 wt. % and each wt. % is based on the total weight of the alloy. The first part may at least partially surround the second part when seen in a cross section.

[Heiko Specht, Frank Kruger] An electrode structure made of noble metal or a noble metal alloy having a thickness of ≦100 μm is provided for implants. The electrode structure has an electrode core made of gold, silver, copper, or an alloy of at least two of these elements, and the electrode core is completely encased by a first coating, which is formed from platinum, iridium, or ruthenium.

[Matthias Frericks, Oliver Keitel, Frank Kruger, Heiko Specht, Hans-Jurgen Wachter, Christiane Leitold] DE Hanau A stimulation electrode is provided having an electrically conducting electrode base member which is partially covered with an electrically insulating ceramic layer. The ceramic layer is formed of an oxide and/or an oxynitride of at least one metal of the group of titanium, niobium, tantalum, zirconium, aluminum and silicon. Various methods are provided for production of the stimulation electrode, including methods in which the ceramic layer is formed in situ by a thermal, chemical or electrochemical oxidation or oxynitridation process. The stimulation electrode may be used as a cardiac pacemaker electrode, a neuro-stimulation electrode, or another human implant.

[Heiko Specht, Andreas Reisinger, Goran Pavlovic, Christina Modes, Frieder Gora, Frederik Roth] DE Hanau One aspect relates to a contacting arrangement for use in a housing of a medically implantable apparatus. Said contacting arrangement includes an electrical feedthrough device that includes at least one electrically insulating main feedthrough member and at least one electrical conducting element. The conducting element is designed to establish at least one electrically conducting connection between an interior of the housing and an exterior through the main feedthrough member. The conducting element is hermetically sealed with respect to the main feedthrough member. The at least one conducting element comprises at least one cermet. The contacting arrangement further includes an electrical filter structure which is arranged on a face of the feedthrough device.
