Abstract
One aspect relates to a housing for an active implantable medical device, whereby the housing, at least parts thereof, includes an electrically insulating ceramic material, and has at least one electrically conductive conducting element, whereby the at least one conducting element is set up to establish at least one electrically conductive connection between an internal space of the housing and an external space. One aspect provides the at least one conducting element to include at least one cermet, whereby the housing and the at least one conducting element are connected in a firmly bonded manner.
Claims11
A housing for an active implantable medical device, comprising:
- a ceramic region comprising an electrically insulating ceramic material forming a pocket;
- at least one electrically conductive conducting element in the ceramic region;
- and
- a housing rim defining a housing opening;
- whereby electronics of the medical devices are insertable through the housing opening into the pocket;
- whereby a metallic lid is sealed to the housing rim thereby sealing the housing opening;
- whereby the at least one conducting element establishes at least one electrically conductive connection between an internal space of the housing and an external space;
- characterized in that the at least one conducting element comprises at least one cermet;
- whereby the housing and the at least one conducting element are coupled in a firmly bonded manner;
- and
- characterized in that the metallic lid consists only of metal and does not include the conducting element.
An active implantable medical device comprising:
- a housing, the housing comprising:
- an electrically insulating ceramic material;
- and
- at least one electrically conductive conducting element;
- whereby the at least one conducting element establishes at least one electrically conductive connection between an internal space of the housing and an external space;
- characterized in that the at least one conducting element comprises at least one cermet comprising a ceramic material and a metallic material;
- whereby the insulating ceramic component of the housing and the ceramic component of the cermet are identical such that the housing and the at least one conducting element are coupled in a firmly bonded manner;
- and
- characterized in that the metallic lid does not include the conducting element.
