Abstract

A medical implantable lead adapted to be implanted into a human or animal body for monitoring and/or controlling of an organ inside the body has a fixation in a distal end, which is adapted to fix a distal end of the lead to the organ, an electrode member in the distal end adapted to be in contact with tissue of the organ and receive and/or transmit electrical signals from and/or to the organ, and at least one electrically conducting coil, which includes one or more electrically conducting helical wires and that is adapted to connect the electrode member in the distal end with a monitoring and/or controlling device in a proximal end of the lead. One or more of the individual wires of the coil has a wire core that is provided with a surrounding electrically insulating layer, which in turn is provided with a surrounding electrically conducting shield layer, and the coil is close lapped such that electrically conducting shield layers of adjacent loops of the coil are in electrical contact with each other.
