Abstract
Embodiments include implantable neurostimulation leads configured to reduce current leakage following implantation in a patient's body, and methods of manufacturing such leads. A lead includes a lead body with proximal apertures and distal apertures; a lumen extending through the lead body; electrodes at a distal portion of the lead body and connector interfaces at a proximal portion of the lead body; conductors extending through the lead body, with their proximal ends exiting via respective proximal apertures to couple with a respective connector interfaces, and their distal ends exiting the interior of the lead body via respective distal apertures to couple with a respective electrodes; and an electrically nonconductive filler element for occupying gaps in the interior of the lead body resulting from the exit of conductors from the lead body.
