Implantable electrode line device for reducing undesirable effects of electromagnetic fields

An implantable medical device comprising:

• at least one elongated electric line with at least two function conductors, which are respectively multi-stranded and of which each function conductor is connected to at least one respective function electrode pole to deliver treatment signals or to record diagnostic signals in a first function conductor (100) and a second function conductor (200);
• wherein said first function conductor of the at least two function conductors has at least one first strand (100.1,100.2), which, in a course of a longitudinal extension of the first function conductor in at least one first longitudinal section (L1), which forms only a partial section of the longitudinal extension of the first function conductor, has a first coupling (230) with the second function conductor (200) of the at least two function conductors, which coupling is configured to couple electromagnetic radio-frequency waves guided in the second function conductor at least in part in the at least one first strand (100.1,100.2) of the first function conductor and not in at least one of the second strand (100.3) of the first function conductor, and in which
• the at least one first strand (100.1,100.2) in the course of the longitudinal extension of the first function conductor (100) in at least one second longitudinal section (L2) different from the first longitudinal section (L1) has a second coupling with the at least one second strand (100.3) of the first function conductor (100), which is configured to couple electromagnetic radio-frequency waves guided in the at least one first strand at least in part in the at least one second strand of the first function conductor.
