Abstract
The present invention is directed toward providing a composite lead body design for pacing and defibrillation leads. This lead body design improves the lead crush resistance in the lead segment that is implanted in the patient's clavicular region, while maintaining good fatigue resistance in the lead segment implanted in the heart. The clavicular segment has a generally flat profile. By flattening the clavicular segment proximal to the venous entry site, the lead will have a lower profile. Also, by substantially co-aligning the conductors within the clavicular segment, the crush resistance of the lead is significantly improved.
