Insertion tool for paddle-style electrode
First Claim
1. A system for implanting a paddle-style electrode in a patient without an insertion needle, the system comprising:
- a lead comprisinga paddle-style electrode platform including a distal end, a proximal end, a back surface, an active surface opposite the back surface, side edges between the back and active surfaces, a plurality holes in one or more of the back surface, active surface, or the side edges of the electrode platform, and a plurality of electrode contacts formed in two or more columns and disposed on the active surface, wherein the plurality of holes comprises a first hole and a second hole, anda plurality of conductive wires coupled to the plurality of electrode contacts and extending away from the electrode contacts and out of the proximal end of the paddle-style electrode platform; and
an insertion tool to implant the paddle-style electrode platform in the patient without using an insertion needle, the insertion tool including a platform engager comprising a handle a plurality of pins configured to engage the plurality of holes of the electrode platform to guide the electrode platform during placement of the electrode platform in the patient, wherein the plurality of pins comprises a first pin and a second pin.

Abstract
The present disclosure describes various embodiments of an insertion tool that affords steerability of the paddle-style electrode during implantation without causing damage to the insulation and/or the contacts of the paddle-style electrode. One embodiment is described as having a “pin fork” configuration; another a “shovel” configuration; and yet another has tabs or a lumen on the paddle-style electrode for facilitating the insertion of a stylet. The various embodiments for the insertion tool allow for adjustments of the paddle-style electrode in both the medial/lateral and inferior/superior directions allowing the surgeon to steer the paddle-style electrode to the desired stimulation site within the epidural space of the spinal column.
