The present disclosure relates to an implantable medical device such as a medical electrical lead. The implantable medical device comprises an electrical connector assembly, an electrode, and an elongated lead body having a proximal end and a distal end. The lead body comprising an elongated conductor, a coiled conductor, and an insulative cover surrounding the coiled conductor. The insulative cover comprises a set of ports along a distal portion of the lead body and adjacent the electrode. The electrode is located on the lead body distal to the electrical connector assembly. The coiled conductor extends distally from the electrical connector assembly within the elongated lead body and is mechanically coupled to the electrode. The elongated conductor extends distally from the connector assembly and is electrically coupled to the electrode.
