Abstract: A lead assembly includes an implantable lead. Electrodes are disposed along a distal end of the lead in an electrode array. Terminals are disposed along a proximal end of the lead in a proximal-most terminal array and a medial terminal array. A terminal extension electrically couples to the medial terminal array. A port is defined in a connector at a first end of the terminal extension. The port has a first end and an opposing second end and forms a continuous passageway therebetween. The port receives the medial terminal array. A contact array includes connector contacts that are disposed within the port and that couple electrically with a terminal array disposed along a second end of the terminal extension. The contact array couples electrically with terminals of the medial terminal array of the lead when the medial terminal array is received by the port.

Abstract: A stimulation lead includes an elongate body having a proximal portion and a distal portion and has a multilumen tube extending along the elongate body and defining a central lumen and a plurality of peripheral lumens disposed circumferentially around the central lumen; a plurality of conductors, at least one of the conductors extending along the central lumen and a remainder of the conductors extending along the plurality of peripheral lumens with at least one of the conductors in each peripheral lumen; a plurality of terminals disposed along the proximal portion of the elongate body and electrically coupled to proximal ends of the conductors; and a plurality of electrodes disposed along the distal portion of the elongate body and electrically coupled to distal ends of the conductors. Each of the conductors is coupled to at least one terminal and at least one electrode.

Abstract: An implantable stimulation lead includes a lead body having a proximal end and a distal end; a plurality of electrodes disposed along the distal end of the lead body; a plurality of terminals disposed along the proximal end of the lead body, and a plurality of conductors disposed in the lead body and including a first conductor and a second conductor. Each conductor electrically couples at least one of the electrodes to at least one of the terminals. The first conductor has a RF impedance that is at least 25% greater in magnitude than the second conductor.
