Patent ID: 8886320

Claim:
An electrical bushing for an implantable device comprising: an electrically insulating base body; and at least one electrically conductive bushing body that is embedded in at least one bushing opening that extends through the base body, whereby the base body is produced from a sintered ceramic material, characterized in that the at least one bushing body is made of a sintered cermet material or a sintered metallic material, whereby the base body and the at least one bushing body comprise a firmly bonded sintered connection; characterized in that the at least one bushing body and the at least one bushing opening in the base body, at least sections thereof, have complementary shapes with non-parallel edges such that slippage is prevented of the bushing body through the bushing opening; which is produced by: forming at least one bushing body green blank from a cermet slurry, a cermet powder, a metal powder and/or a slurry made of a metal powder, whereby a shape of the at least one bushing body green blank and a shape of the at least one bushing opening are complementary to each other at least in sections thereof and prevent slippage of the bushing body green blank through the bushing opening; and applying at least one force to the bushing body green blank and sintering while applying the at least one force.
