1. A medical lead comprising:
- a lead body;
at least one lumen disposed within the lead body; and
a coil conductor disposed within the at least one lumen, the coil conductor comprising;
a first coiled segment comprising a first number of filars and a first pitch;
a second coiled segment comprising a second number of filars and a second pitch; and
a junction member coupled to an end of the first coiled segment and an end of the second coiled segment.

15. A method of constructing a coil conductor having at least a first segment and a second 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 first segment, wherein the first section comprises a first outer diameter and the first segment comprises the first number of at least one filars, a first pitch, and a first inner diameter, wherein the winding to form the first segment ends at a transition point; and winding a second number of at least one filars beginning at the transition point into a coiled configuration over a second section of the mandrel to form the second segment, wherein the second section comprises a second outer diameter and the second segment comprises the second number of at least one filars, a second pitch, and a second inner diameter, wherein at least one of the first number of filars, the first pitch, the first inner diameter, and the first outer diameter is different from at least one of the second number of filars, the second pitch, the second inner diameter, and the second outer diameter, wherein the at least one filar is a coated filar and wherein the method further comprises removing the coating while winding the at least one filar to form either the first segment or the second segment, whereby one of the first and second segment is uncoated. - View Dependent Claims (16, 17, 18, 19)
