Patent ID: 8909354

Claim:
An electrical stimulation lead, comprising: a lead body having a distal end portion and a proximal end portion; a plurality of first contacts disposed along one of the distal end portion or the proximal end portion of the lead body; a contact assembly disposed along the other of the distal end portion or the proximal end portion of the lead body, the contact assembly comprising a tubular-shaped composite structure comprising a plurality of layered elements mechanically coupled together and rolled into a tube, each of the plurality of layered elements comprises a first electrically-nonconductive film, a second electrically-nonconductive film, and a plurality of micro-circuits laminated between the first electrically-nonconductive film and the second electrically-nonconductive film, the micro-circuits formed from a first material and each having a first end portion and an opposing second end portion, and a plurality of second contacts disposed over the composite structure, wherein the plurality of second contacts are electrically-coupled directly to the plurality of micro-circuits; and a plurality of lead-body conductors electrically coupling the plurality of first contacts to the plurality of second contacts, wherein each of each of the plurality of lead-body conductors is attached to the second end portion of at least one of the plurality of micro-circuits.
