Abstract: A medical lead system includes a lead body, a plurality of electrical conductors, and a plurality of electrodes. The lead body may include a distal end and a proximal end defining a longitudinal axis of the lead body. The plurality of electrical conductors extending about the longitudinal axis of the lead body. The plurality of electrodes is positioned around an outer perimeter of the lead body. An inner surface of each of the plurality of electrodes defines an inner perimeter. Each respective electrode of the plurality of electrodes is electrically coupled to a respective electrical conductor of the plurality of electrical conductors. Each electrode of the plurality of electrodes includes at least one electrode locking feature extending into the lead body from the inner perimeter.

Abstract: Implantable medical leads and/or lead extensions include a band that encapsulates a portion of conductors of the lead and/or lead extension. The band may be reflowed in order to provide the encapsulation of the conductors. The band may further be used to create a seal together with the surrounding lead body and an additional object such as a stiffener rod, stylet tube, and/or molding stylet, to allow a proximal area of a lumen of the lead body to be injection molded while prevent the injection molding material from proceeding past the band. When a stiffener rod is present in a proximal area of the lead and/or lead extension, additional stiffness is provided to the lead body to resist buckling of the lead body during insertion of the proximal end. The band may be bonded to the stiffener rod to fix the position of the stiffener rod relative to the conductors.

Abstract: An assembly for forming a medical lead includes a lead body, a plurality of electrical conductors extending about a longitudinal axis of the lead body, and at least one segmented electrode preform that includes an electrically conductive ring and an insulator portion within the electrically conductive ring. The electrically conductive ring includes a plurality of electrode portions and a plurality of raised portions that alternate continuously around the ring. Each of the plurality of electrode portions is continuous at a radius from a center of the electrically conductive ring that corresponds to an outer perimeter of the medical lead. The insulator portion has a plurality of projections each extending into a respective raised portion of the ring beyond a radius that corresponds to the outer perimeter of the medical lead. Each respective electrode portion is electrically coupled to a respective electrical conductor of the plurality of electrical conductors.
