Abstract:
1. An implantable medical device comprising: a function conductor comprising at least one elongated electrical function conductor configured to transmit therapeutic signals or diagnostic signals or both; a dielectric; and, an additional conductor comprising at least one additional conductor which together with the function conductor forms, in one or more places, a double line which is separated from the function conductor by the dielectric and which is coupled to the function conductor via a coupling impedance, which is dimensioned in such a way that the value of a line wave impedance of the function conductor for a frequency range above a frequency range of the therapeutic or diagnostic signals is much greater than the line wave impedance of the function conductor in the frequency range of the therapeutic or diagnostic signals, so that currents in the frequency range above the frequency range of the therapeutic or diagnostic signals are damped more intensely than the currents which form therapeutic or diagnostic signals, wherein the one or more places of the medical device forming the double line is configured as a sheath wave trap.
