A method for manufacturing a lead includes pre-forming at least one relief section along a length of an elongated conductor having a first end and an opposing second end. The conductor with the pre-formed relief section is inserted into a conductor lumen defined along a length of an elongated lead body. The lead body has a first end and an opposing second end. An electrode is disposed at the first end of the lead body. The first end of the conductor is electrically coupled to the electrode. A terminal is disposed at the second end of the lead body. The second end of the conductor is electrically coupled to the terminal.
