Abstract
Official abstract text for this publication.
One aspect relates to a method for producing an electrical bushing for an implantable device, an electrical bushing, and an implantable device. The method according to one embodiment includes forming a base body from a ceramic slurry and introducing a bushing conductor made of a metal or cermet material with a metal fraction into the base body. The metal fraction in the bushing conductor is provided to decrease towards the base body. It includes sintering the green blank that includes the base body and the bushing conductor.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrical bushing for an implantable device comprising: an electrically insulating base body; and at least one electrically conductive bushing conductor that extends through the base body; wherein the base body is produced from a sintered ceramic material, characterized in that the at least one bushing conductor comprises a metal or cermet material that has been jointly sintered with the base body and has a metal fraction that decreases from the interior of the bushing conductor towards the outside. 2. The electrical bushing according to claim 1 , characterized in that the base body is connected circumferentially to a wreath-shaped fringe body made of a cermet material through a firmly bonded sintered connection, whereby the fringe body comprises a receiving opening, in which the base body is arranged. 3. The electrical bushing according to claim 1 , characterized in that it is hermetically sealed for gases and liquids. 4. The electrical bushing of claim 1 , which is produced by: forming the base body from a ceramic slurry; introducing the bushing conductor made of a metal powder, metal slurry, cermet powder and/or cermet slurry into the base body, whereby the metal fraction in the bushing conductor is provided to decrease towards the base body; and sintering the green blank that comprises the base body and the bushing conductor. 5. An implantable device comprising: an electrical bushing having an electrically insulating base body; and at least one electrically conductive bushing conductor that extends through the base body; wherein the base body is produced from a sintered ceramic material; and wherein the electrical bushing is characterized in that the at least one bushing conductor comprises a metal or cermet material that has been jointly sintered with the base body and has a metal fraction that decreases from the interior of the bushing conductor towards the outside. 6. The implantable device according to claim 5 , characterized in that the electrical bushing is surrounded by transition layers comprising a cermet and a metal fraction that is lower than the metal fraction of the busing conductor.
