Implantable leads with a conductor coil having two or more sections

A method of constructing a coil conductor of an implantable medical lead, the coil conductor having at least a proximal segment and a distal segment, the method comprising:

• winding a first number of at least one filars into a coiled configuration over a first section of a mandrel to form the proximal segment, wherein the first section comprises a first outer diameter, and a first pitch, the proximal segment ending at a transition point and a coating disposed on the at least one filars such at the at least one filars have a coated configuration while the proximal segment is wound;
• removing the coating from a section of the at least one filars;
• and
• winding a second number of the at least one filars from the transition point into a coiled configuration over a second section of the mandrel to form the distal segment, the second section comprising a second outer diameter, and a second pitch, the first pitch and the first inner diameter are different from the second pitch and the second outer diameter,
• wherein the coating is removed from the at least one filars after the winding of the proximal segment along a section of the at least one filars that will form the distal segment such that the at least one filars is coated along the proximal segment and uncoated along the distal segment.
