1. A method for manufacturing a lead, the method comprising:
- inserting a conductor into a conductor lumen defined along a length of an elongated lead body, the lead body having a first end and an opposing second end, wherein the conductor lumen defines a plurality of helical sections separated from one another by straight, wherein each of the helical sections is arranged in counterrotaion to adjacent ones of the plurality of helical sections;
disposing a first conductive contact at the first end of the lead body with a first gap formed between the first conductive contact and the first end of the lead body;
electrically coupling the first end of the conductor to the first conductive contact;
disposing a second conductive contact at the second end of the lead body;
electrically coupling the second end of the conductor to the second conductive contact; and
reducing the first gap between the first conductive contact and the first end of the lead body, wherein reducing the first gap causes the conductor to form at least one first relief section.

Abstract
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.
