Abstract
On aspect relates to an electrical bushing for use in a housing of an implantable medical device. The bushing includes at least one electrically insulating base body and at least one electrical conducting element. 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 at least one conducting element comprises at least one cermet such that the conducting element is hermetically sealed with respect to the base body. The bushing includes an electrical filter structure. The at least one conducting element provides at least a one conducting section of the filter structure and the base body provides at least one dielectric section of the filter.
Claims19
An electrical bushing for use in a housing of an implantable medical device, the electrical bushing comprising:
- at least one electrically insulating base body;
- and
- at least one electrical conducting element, wherein 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;
- wherein the at least one conducting element comprises at least one cermet such that the conducting element is hermetically sealed with respect to the base body;
- and
- an electrical filter structure, wherein the at least one conducting element provides at least a one conducting section of the filter structure and the base body provides at least one dielectric section of the filter.
A method for the manufacture of an electrical bushing including a filter structure for an implantable medical device, the method comprising:
- generating at least one base body green compact for at least one base body from an electrically insulating material;
- forming at least one cermet-containing conducting element green compact for at least one conducting element;
- introducing the at least one conducting element green compact into the base body green compact;
- subjecting the base body green compact with the at least one base body green compact to firing in order to obtain at least one base body with at least one conducting element;
- and
- forming at least one conducting section of the filter structure in the electrical bushing using the cermet-containing conducting element green compact of the at least one conducting element.
