US Patent 7941227 Implantable electric stimulation system and methods of making and using

An insertion kit includes a lead and a splitable member configured and arranged for receiving the lead when implanting the lead into a patient. The lead has a distal end and at least two proximal ends. The lead includes a plurality of electrodes disposed at the distal end, a plurality of terminals disposed at the proximal ends, and a plurality of conductive wires coupling the plurality of electrodes electrically to the plurality of terminals. The lead also includes a junction coupling the distal end of the lead to the proximal ends of the lead. The splitable member defines a lumen for receiving the distal end of the lead and is configured and arranged to divide into at least two parts for removal of the splitable member from the lead upon implantation of the lead into the patient.
