ABSTRACT:
A wireless feedthrough assembly, for coupling leads received in the receptacles of a connector assembly to the electronic circuit within a cardiac pacemaker, includes a weld ring mounted in hermetically sealed fashion within a housing wall of the pacemaker and itself hermetically sealed to an intermediate portion of an elongated, multilayered structure. The multilayered structure includes layers of electrically insulating ceramic material on opposite sides of a planar array of printed conductors extending between a first portion of the structure within the connector assembly and an opposite second portion of the structure within the pacemaker. Connector pads at the ends of the printed conductors within the first portion are coupled to the receptacles of the connector assembly, while contact pads at the exterior of the second portion and coupled by vias to connector pads at the ends of the printed conductors are coupled to the electronic circuits within the pacemaker. Printed ground planes on the multilayered structure form a conductive envelope which shields the printed conductors from electric fields. The contact pads include positive and ground contacts to which are coupled discrete filtering capacitors for limiting the spectrum of frequencies receivable by the connector assembly. A method for making the aforedescribed feedthrough assembly is also disclosed.
