The invention relates to a medical implantable lead for monitoring and/or controlling an organ inside a human or animal body. The lead comprises a first electrode (6I) at a distal end of the lead adapted to be in contact with tissue of the organ, a connector at a proximal end of the lead adapted to be connected to a monitoring and/or controlling device, a conducting arrangement comprising a first conducting coil (9I) of at least one electrically conducting wire (10I) for connecting the first electrode electrically to the connector to receive and/or transmit electric signals from and to the tissue, respectively, and a flexible tubing (7) surrounding the lead from the proximal to the distal end, wherein the lead is tapered in a distal portion and has a smaller cross sectional dimension at the distal portion than at the rest of the lead. The first conducting coil (9I) is terminated at a termination point (14) on a distance from the distal end, and the conducting arrangement comprises also a first end conductor, in form of a non-coiled electric conductor (11I) or an eccentrically positioned small diameter coil (13), which connects the first electrode (6I) electrically with the coil.
