Abstract
A medical implantable lead of the kind being adapted to be implanted into a human or animal body for monitoring and/or controlling of an organ inside the body has a penetrating fixation element in a distal end, which is adapted to penetrate into the tissue of the organ to fixate the lead such that a distal end of the lead will be in contact with the organ. The lead also has an electrode member to receive and/or transmit electrical signals from and/or to the organ. The lead has in a distal portion a movable member, which is displaceable in an axial direction of the lead and is actuated by a resilient member to be, in an initial state, maximally protruded in a distal direction in relation to the lead and which comprises a radiopaque material for forming of a first indication marker. The lead also has a second indication marker of a radiopaque material in relation to which the movable member is displaceable, and the first and the second indication markers are arranged such that, when observing the lead in an implanted state by means of fluoroscopy, it will be recognizable from the relative positions of the first and second indication markers, whether the distal end of the lead is in c…
