A method of forming a stimulation lead includes forming an implantable lead body, including helically winding at least one cable about a mandrel to form a coiled cable assembly in a first, restrained state. Helically winding the at least one cable includes applying a tensile force to the at least one cable as the at least one cable is wound about the mandrel. Forming the lead body also includes releasing the tensile force from the at least one cable to allow the coiled cable assembly to release stored mechanical energy and transition from the restrained state to a second, relaxed state in which the coiled cable assembly is substantially free of stored mechanical energy. The method further includes subjecting the lead body to a reflow process by applying heat to the lead body, where the tensile force is released prior to the lead body being subjected to the reflow process.

A post-fitting shield member to be post-fitted with an electric wire is a plated fiber bundle wound in coil form and formed by performing metal plating on a high-strength fiber member. A manufacturing method of a shielded wire consists of an insertion step of inserting an electric wire into the post-fitting shield member having a coil shape; a first fixing step of fixing one end portion of the post-fitting shield member into which the electric wire was inserted in the insertion step; an expansion step of expanding the post-fitting shield member that was fixed in the first fixing step toward the side of its other end portion; and a second fixing step of fixing the other end portion of the post-fitting shield member that was expanded in the expansion step.

An elastic conductor includes a stretchable base, and conductors each having a longitudinal shape, being arranged on a surface of the stretchable base, and having a lower specific resistance and a higher modulus of elasticity than the stretchable base. In the first state, the conductors are spaced apart from each other in the second direction perpendicular or substantially perpendicular to the first direction, and are continuous in a section extending in the first direction as seen in the second direction from one end of the section to the other end of the section, in which a distance between the conductors adjacent to each other in the second direction in the second state is shorter than a distance between the conductors adjacent to each other in the second direction in the first state.
