1. A method of insulating a conductive element in a medical electrical lead comprising:
- introducing an ePTFE cover over at least one conductive element;
coupling the at least one conductive element around a mandrel to form a coil shape in the at least one conductive element;
annealing the ePTFE cover over the at least one conductive element and thereby setting the coiled shape in the at least one conductive element; and
removing the coil shape including the at least one conductive element and the annealed ePTFE cover from the mandrel.

Abstract
A medical device lead is presented. The lead includes one or more jacketed conductive elements. The jacket comprises one or more covers. A first cover of expanded polytetrafluoroethylene (ePTFE) is in direct contact with the at least one conductive element. At least one conductive element and a ePTFE cover are coiled. The coiled conductive element can substantially retain its original coiled shape.
