Retractor and tools for implantation of electrical stimulation leads and methods of using and manufacture
First Claim
1. An implantation kit, comprising:
- a retractor for implanting a paddle lead of an electrical stimulation system, the retractor comprising;
a shaft defining a length, an interior lumen, a first end for receiving tools or the paddle lead, and a second end opposite the first end and configured and arranged for insertion into tissue of a patient;
a handle coupled to the shaft; and
at least one divider disposed within the interior lumen and dividing a portion of the interior lumen into at least two compartments, wherein the at least one divider extends from at or near the first end of the shaft and no more than 70% of the length of the shaft; and
a paddle lead, comprising;
a paddle body,at least one lead body having a distal end portion, a proximal end portion, and a longitudinal length, the distal end portion of each of the at least one lead body coupled to the paddle body,a plurality of electrodes disposed in at least two columns on the paddle body,a plurality of terminals disposed along the proximal end portion of each of the at least one lead body, anda plurality of conductors electrically coupling the plurality of terminals to the plurality of electrodes,wherein at least one of the compartments of the retractor is sized for implantation of the paddle lead therethrough.
