Claim 15:
16. An implantable electrode lead, comprising:
an outer tube, at least one electrode line, at least one electrode pole, and a stub line;
wherein:
the implantable electrode lead has an elongate structure;
the outer tube, having a distal end and a proximal end, wherein the implantable electrode lead is connectable in a region of the proximal end to an active device;
the at least one electrode is line arranged in the outer tube extending from the proximal end to the distal end;
the at least one electrode pole is arranged in a region of the distal end and is electrically connected to the at least one electrode line, for electrically contacting tissue surrounding the implantable electrode lead when the implantable electrode lead is in an implanted state; and
the stub line is arranged in the outer tube and is connected in the region of the distal end or the region of the proximal end to the at least one electrode line in order to extend an effective line length of the at least one electrode line,
wherein the stub line has a mechanical stub line length that extends along a length of the outer tube in parallel with the at least one electrode line;
wherein the stub line includes first and second ends, wherein only the first end of the stub line is electrically connected to the at least one electrode line along a length of the at least one electrode line, and the second end of the stub line is opposite the first end and is a free end which is unconnected to any element.
