1. A housing of an active medical electronic device, comprising:
a metal wall having an outer side and an inner side, the wall being provided with at least one electrically isolated and sealed feedthrough for an electrical connection through the wall, the housing further including in an area of the feedthrough:
a contour groove, defining in the wall a metal islet electrically and physically isolated from the rest of the wall, said groove extending through a thickness of the wall;an electrically insulating outer layer on the outer side of the wall, extending over at least a region in alignment with the groove and beyond either side of the groove, the insulating outer layer comprising a recess formed in alignment with the islet through the entire thickness of the outer insulating layer;an electrically conductive outer layer formed outside of the insulating layer and extending over the region in alignment with the groove and beyond either side of the groove;an electrically insulating inner layer formed on the inner side of the wall and extending over a region of the islet;an electrically conductive inner layer formed outside of the insulating inner layer and extending over the region of the islet, forming a contact pad for contact with the islet on the inner side of the wall;wherein the electrically conductive outer layer and the electrically conductive inner layer create a series filter capacitor; andwherein the islet is mechanically supported by the insulating and conductive outer layers. |
