Patent application numberDescriptionPublished
20080317948Method for Producing a Stimulation Electrode - 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.12-25-2008
20100159396METHOD FOR PRODUCTION OF A MEDICAL MARKER - A method is provided for production of a medical marker (4) made of an X-ray-opaque material, including the following steps: 06-24-2010
20100211147ELECTRICALLY CONDUCTING MATERIALS, LEADS, AND CABLES FOR STIMULATION ELECTRODES - One aspect is a stranded wire containing numerous coils. The stranded wire is configured as an electrical connection between an electrical stimulation device that is connected to the proximal end of the stranded wire, and an electrode connected to the distal end of the stranded wire. At least one coil includes a tantalum or niobium-based metal.08-19-2010
20100233507DEVICE WITH AT LEAST TWO INTERCONNECTED METAL PARTS - One aspect is a device including at least two interconnected metal parts. The two interconnected parts are formed from metals with different melting temperature from the group consisting of the elements Pt, Pd, Ag, Au, Nb, Ta, Ti, Zr, W, V, Hf, Mo, Co, Cr, Ni, Ir, Re, Ru as well as alloys on the basis of at least one of those elements. The metal part with the lower melting temperature is fused onto the metal part with the higher melting temperature and both parts are friction-locked and/or form-locked with each other.09-16-2010
20100305671STIMULATION ELECTRODE - One aspect relates to a stimulation electrode including an electrically conducting base body. The base body encompasses tantalum and is at least partially covered with a porous tantalum oxide layer, which is anodically applied by means of high voltage pulses. Provision is made according to an embodiment for a metallic protective layer to cover the porous tantalum oxide layer so as to prevent a hydrogen embrittlement.12-02-2010
20110014399METHOD FOR PRODUCING A STIMULATION ELECTRODE - 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.01-20-2011
20110033335PRODUCING AN ALLOY WITH A POWDER METALLURGICAL PRE-MATERIAL - One aspect is a method for producing an alloy, whereby the alloy includes at least a first metal and a second metal, whereby firstly a powder metallurgical route and subsequently a melt metallurgical route is used sequentially in order to generate the alloy from the, at least, first metal and the second metal. The method includes grinding the first metal into a first metal powder, grinding the second metal into a second metal powder, mixing the first metal powder and the second metal powder to produce a blended powder, generating a blended body from the blended powder by the powder metallurgical route, and generating the alloy by melting the blended body by the melt metallurgical route.02-10-2011
20110034965CERMET-CONTAINING BUSHING FOR AN IMPLANTABLE MEDICAL DEVICE - One aspect relates to an electrical bushing for an implantable medical device, having an annulus-like holding element for holding the electrical bushing in the implantable medical device, whereby the holding element includes a through-opening, at least one elongated conduction element extends through the through-opening, and an insulation element for forming a hermetic seal between the holding element and the conduction element is arranged in the through-opening. One aspect provides for the at least one conduction element to include a cermet.02-10-2011
20110034966ELECTRICAL BUSHING FOR AN IMPLANTABLE MEDICAL DEVICE - One aspect relates to an electrical bushing for an implantable medical device, having an annulus-like holding element for holding the electrical bushing in the implantable medical device, whereby the holding element includes a through-opening, at least one elongated conducting wire extends through the through-opening, and an insulation element for forming a hermetic seal between the holding element and the conducting wire is arranged in the through-opening. One aspect provides for a cermet-containing bearing element to be arranged between the insulation element and the conducting wire.02-10-2011
20110129386USE OF POWDER-METALLURGICAL PRE-MATERIAL FOR PRODUCING AN NB ALLOY THAT IS FREE OF INCLUSIONS - One aspect discloses a method for producing an alloy, whereby the alloy consists of a first metal, a second metal, a third metal, and a fourth metal, and the first metal, the second metal, the third metal, and the fourth metal are selected from the group consisting of the metals, niobium, zirconium, tantalum, and tungsten, and the method includes the steps of 06-02-2011
