Described is a medical device lead (14) including a lead body (36) having a conductor lumen (44, 46, 48) including an inner surface. The lead also includes a conductor assembly (38, 40, 42) extending through the conductor lumen, the conductor assembly comprising a conductor member (50, 54, 56) and an outer insulative layer (52, 58, 60), and an electrode coupled to the conductor cable. The outer insulative layer includes a textured external surface (62, 64, 66) that reduces the coefficient of friction between the outer insulative layer and the inner surface of the conductor lumen through which the conductor assembly extends. Methods of forming the conductor assembly are also described. |
