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 conducting wire extends through the through-opening, and an insulation element for forming a hermetic seal between the holding element and the conducting wire is arranged in the through-opening. One aspect provides for a cermet-containing bearing element to be arranged between the insulation element and the conducting wire.
Claims15
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 conducting wire extends through the through-opening;
- an insulation element for forming a hermetic seal between the holding element and the conducting wire is arranged in the through-opening;
- characterized in that a cermet-containing bearing element is arranged between the insulation element and the conducting wire.
Use of a cermet-containing bearing element between an insulation element and a conducting wire in an electrical bushing for an implantable medical device.
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 conducting wire extending through the through-opening;
- an insulation element forming a hermetic seal between the holding element and the conducting wire arranged in the through-opening;
- and
- a cermet-containing bearing element arranged between the insulation element and the conducting wire.
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 bearing element green compact for a bearing element;
- introducing the at least one bearing element green compact into the insulation element green compact;
- firing the insulation element green compact and the at least one bearing element green compact to obtain an insulation element with at least one bearing element;
- inserting an elongated conducting wire into the at least one bearing element;
- and
- surrounding the insulation element, at least in part, with a holding element.
