摘要:
A medical implantable lead is adapted to be implanted into a human or animal body for monitoring and/or controlling of an organ inside the body, and has in a distal end, a combined fixation means and electrode member in form of a helix, which is rotatable in relation to the lead and extendable out from the distal end by rotation of a tubular torque transferring member. The helix is electrically connected to a connector in the proximal end by at least one electrically conducting wire, which is formed as an electrically conducting coil, which is separate from the tubular torque transferring member and that includes one or more individual wires each having an electrically conducting wire core and a surrounding electrically insulating layer. The tubular torque transferring member has no electrically conducting function to or from the helix. The lead is arranged such that the electrical connection between the helix and the conducting wire is always maintained regardless of the rotational position of the helix while no electrical connection is present between the helix and the tubular torque transferring member although the helix is rotatable by the tubular torque transferring member.
