A new hermetically-sealed contact feedthrough for cardiac pacemakers and defibrillators for the connection between internal device electronics and external components, a flat ceramic disk () being used as an insulating main carrier, in which openings () are situated, into which various electrode embodiments () may be inserted as through contacts. Using a metal flange or metal-plated vapor deposition zone (), the ceramic disk may be soldered directly onto the implant housing (). In addition, active and passive auxiliary components () may be applied directly to the ceramic. The main carrier may be implemented as a multilayer ceramic (), so that rewiring levels and shielding components () may be integrated in the feedthrough. The feedthrough according to the present invention allows novel construction variants, above all things having orientation to multipolar systems, through use of standardized ceramic semifinished products.

Filter feedthrough for implants

Housing for medical implant, such as cardiac pacemaker, defibrillator, cardioverter, etc. Housing including hollow housing and terminal body attached to hollow housing, which has electrical terminal(s), situated in an externally accessible cavity of the terminal body, for connecting an electrode line, and terminal body including a base body made of electrically insulating plastic, connected to hollow housing and carries electrical supply lines and electrical contacts, which are electrically connected thereto, for the electrical terminal so that the contacts are connected via the electrical supply lines to electrical components in the interior of the hollow housing, electrical supply lines being welded to the electrical contacts and the electrical supply lines and electrical contacts, which are welded to one another, being embedded in the base body and thus fixed in their final position, and the base body being glued to the hollow housing using an adhesive between hollow housing and terminal body.

Housing for a medical implant

The invention concerns an electromedical implant for intracardial coronary therapy comprising an implant housing in which functional component parts of the implant, namely a circuit, a battery and the like, are disposed. It is characterized in that the battery () has a flat side (), an underside () and a peripherally extending narrow side () and the battery () is arranged with its underside () on an internal base surface () of the implant housing () and the circuit () is arranged in adjacent relationship with a flat side () of the battery ().
