Abstract
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.
Claims17
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 comprises a through-opening;
- at least one elongated conduction element extends through the through-opening;
- an insulation element for forming a hermetic seal between the holding element and the conduction element is arranged in the through-opening;
- characterized in that the at least one conduction element comprises components made of cermet.
An implantable medical device comprising:
- an electrical bushing having an annulus-like holding element for holding the electrical bushing in the implantable medical device;
- wherein the holding element comprises a through-opening;
- at least one elongated conduction element extending through the through-opening;
- and
- an insulation element forming a hermetic seal between the holding element and the conduction element arranged in the through-opening;
- wherein the at least one conduction element comprises cermet.
A method for producing an electrical bushing for an implantable medical device, the method comprising:
- generating an insulation element green compact for an insulation element from an insulating composition of materials;
- forming at least one cermet-containing conduction element green compact for a conduction element;
- introducing the at least one conduction element green compact into the insulation element green compact;
- firing the insulation element green compact and the at least one conduction element green compact to obtain an insulation element with at least one conduction element.
