Patent ID: 8712542

Claim:
An implantable lead comprising: a lead body with a distal end portion, a proximal end portion, and an inner core substrate having a surface, the lead body configured and arranged for implanting into a patient; a plurality of conductors attached directly to the surface of the inner core substrate by deposition, each conductor comprising at least one layer of at least one conductive material extending between the proximal end portion and the distal end portion of the lead body; a patterned insulator layer distinct from the inner core substrate, the patterned insulator layer attached directly to the plurality of conductors such that each conductor of the plurality of conductors is sandwiched between the inner core substrate and the patterned insulator layer, the patterned insulator layer attached to the plurality of conductors such that at least two regions of each conductor of the plurality of conductors remain exposed through the insulator layer, including a first exposed region at the proximal end portion of the lead body and a second exposed region at the distal end portion of the lead body; a patterned terminal layer, defining a plurality of separated terminals, attached by deposition to the proximal end portion of the lead body, wherein for each conductor of the plurality of conductors at least one terminal of the plurality of separated terminals is attached by deposition to the conductor via the first exposed region of that conductor, wherein each terminal of the plurality of separated terminals is attached by deposition to at least one of a portion of the patterned insulator layer or the inner core substrate along the proximal end portion of the lead body; and a patterned electrode layer, defining a plurality of separated electrodes, attached by deposition to the distal end portion of the lead body, wherein for each conductor of the plurality of conductors at least one electrode of the plurality of separated electrodes is attached by deposition to the conductor via the second exposed region of that conductor, wherein each electrode of the plurality of separated is attached by deposition to at least one of a portion of the patterned insulator layer or the inner core substrate along the distal end portion of the lead body.
