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.
Claims9
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 and is configured to transmit electrical signals between inside and outside the implantable medical device;
- an insulation element comprising aluminum oxide 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 cermet such that cermet is adjacent the insulation element thereby forming the hermetic seal therebetween without welding or soldering and in that the cermet comprises aluminum oxide in a metallic matrix.
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 comprising aluminum oxide 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, such that cermet is adjacent the insulation element thereby forming a hermetic seal therebetween without welding or soldering and wherein the cermet comprises aluminum oxide in a metallic matrix.
