METHOD FOR THE MANUFACTURE OF A CERMET-CONTAINING BUSHING
First Claim
1. A method for the manufacture of an electrical bushing for use in a housing of an active implantable medical device,whereby the electrical bushing comprises at least one electrically insulating base body and at least one electrical conducting element;
- whereby 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;
whereby the conducting element is hermetically sealed with respect to the base body;
whereby the at least one conducting element comprises at least one cermet;
characterized in that the method comprises;
forming a base body green compact having a through-opening that extends through the base body green compact from a ceramic slurry or a ceramic powder;
generating at least one conducting element green compact from a cermet slurry or a cermet powder;
producing a bushing blank by combining the at least one conducting element green compact and the base body green compact; and
separating the bushing blank into at least two electrical bushings.

Abstract
One aspect relates to a method for the manufacture of an electrical bushing for use in a housing of an active implantable medical device. The electrical bushing includes an electrically insulating base body and an electrical conducting element. The conducting element is set-up to establish, through the base body, an electrically conducting 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 conducting element includes at least one cermet.
One aspect provides the method including forming a base body green compact having a through-opening that extends through the base body green compact from a ceramic slurry, generating at least one conducting element green compact from a cermet slurry, producing a bushing blank by combining the conducting element green compact and the base body green compact, and separating the bushing blank into two electrical bushings.
