Abstract
An implantable lead includes an inner core substrate. A plurality of conductors that include at least one layer of at least one conductive material are deposited on the inner core substrate. A patterned insulator layer is disposed over the conductors such that at least two regions of each conductor remain exposed through the insulator. A patterned terminal layer defines a plurality of separated terminals that are deposited at a proximal end of the lead. At least one terminal is electrically coupled to each conductor via at least one of the exposed regions of the at least one conductor. A patterned electrode layer defines a plurality of separated electrodes that are deposited at a distal end of the lead. At least one electrode is electrically coupled to each conductor via at least one of the exposed regions of the at least one conductor.
