Abstract

This invention relates to a unipolar or multipolar electrical filter feedthrough device (1) to be introduced into an aperture of housing (26) of an implantable electronic therapeutic device with a feedthrough body (2) to be inserted in the aperture and comprising a fixing means (3) to connect with the housing wall, and with filter means (7) designed as capacitors, that are, on one side, connected—in an electrically conductive manner—with one of the electrical pins (8) that are mutually electrically separated, and, on the other side, with the housing of the therapeutic device carrying a reference potential. Filter means (7) are arranged outside the feedthrough body (2) and are connected with this body in such a manner that they basically stick out into the inside (4) of housing (26) in a freely suspended manner.
