Abstract

A medical lead is provided with multiple insulation layers, or redundant insulation, between conductors, and with a non-coiled tubular lumen. Such a design overcomes problems with perforation of insulation, lead prolapse, and shorting of conductors, among other problems. The lead design includes a multilumen lead body comprised of insulation that defines a stylet lumen and conductor lumens. The conductors may also include a coating of insulation, providing further redundancy in the insulation protecting conductors from one another and reducing the chance of conductors shorting together. The individual conductor lumens allow for slack in the placement of the inserted conductors, which enhances fatigue resistance.
