Abstract
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.

17. A method for implanting a neurostimulation lead into a patient, the method comprising:
-
inserting an obturator into an insertion needle; inserting the insertion needle into a splitable member, the splitable member defining a lumen for receiving the obturator; guiding the splitable member with the obturator to a desired location within the patient; removing the obturator, leaving the splitable member in the patient; inserting into the lumen of the splitable member a distal end of a neurostimulation lead, the neurostimulation lead comprising a plurality of electrodes disposed along the distal end of the neurostimulation lead and a plurality of terminals disposed along at least one proximal end of the neurostimulation lead; separating the splitable member into at least two parts along the length of the lumen; and removing the splitable member from the neurostimulation lead, leaving at least the distal end of the neurostimulation lead implanted in the patient. - View Dependent Claims (18, 19, 20)
