Abstract
A medical device lead includes a proximal connector configured to couple the lead to a pulse generator and an insulative lead body extending distally from the proximal connector. The lead also includes an inner conductor and one or more cable conductors coupled to the proximal connector at a proximal end and extending through the lead body. The lead further includes one or more defibrillation coil electrodes coupled to a distal end of the one or more cable conductors. The one or more defibrillation coil electrodes are disposed around and electrically isolated from the inner conductor. The one or more defibrillation coil electrodes have a first winding direction and the inner conductor has a second winding direction opposite the first winding direction.
