Abstract:
1. A medical device lead comprising: a proximal connector configured to couple the lead to a pulse generator; an insulative lead body extending distally from the proximal connector; an inner conductor coupled to the proximal connector at a proximal end and extending through the lead body; one or more cable conductors coupled to the proximal connector at a proximal end and extending through the lead body, wherein each of the one or more cable conductors is formed from longitudinal wires or filaments that extend straight along the lead, wherein each of the one or more cable conductors is formed from longitudinal wires or filaments that extend straight along the lead; and one or more defibrillation coil electrodes each coupled to a distal end of one of the one or more cable conductors, the one or more defibrillation coil electrodes each disposed around and electrically isolated from the inner conductor, wherein the one or more defibrillation coil electrodes each have a first winding direction and the inner conductor has a second winding direction opposite the first winding direction.
