Systems and methods for coupling conductors to conductive contacts of electrical stimulation systems

摘要

An electrical stimulation lead includes a plurality of conductive contacts disposed at a distal end and a proximal end of a lead body. The plurality of conductive contacts includes a plurality of electrodes and a plurality of terminals. At least one of the conductive contacts is a first conductive contact that includes at least one adhesive aperture defined between an inner surface and an outer surface of the at least one conductive contact. A plurality of conductors each electrically couple at least one of the electrodes to at least one of the terminals. Each first conductive contact has a conductor associated with, and electrically coupled to that first conductive contact. The adhesive is disposed in proximity to the at least one adhesive aperture of at least one first conductive contact to adhesively couple that first conductive contact to the at least one associated conductor.
