1. An insertion tool for a spinal cord stimulation electrode, the insertion tool comprising:
- a first leg;
a second leg coupled to the first leg, the first and second legs being separable for placement around the electrode and resiliently returning to a clamped position, each of the first and second legs generally defining a respective longitudinal axis, each of the first and second legs defining a blade portion offset from the respective longitudinal axis, wherein each of the offset blade portions include an electrode-receiving channel formed therein extending from a proximal-most end of the blade portion to a distal-most end of the blade portion, wherein the electrode receiving channels of each of the first and the second legs are configured to clamp the electrode, wherein the offset blade portions are so dimensioned as to facilitate inserting the electrode into an epidural space and advancing the electrode along the epidural space;
wherein each of the first and second legs includes a respective intermediate angled portion that elevates a first portion of each of the first leg and the second leg above a second portion of each of the first and the second legs, respectively, andwherein the respective blade portions are elevated above both the respective first portions and the second portions of the first and the second legs.

Abstract
The present invention is directed to an insertion tool for a spinal cord stimulation electrode. The insertion tool comprises a first leg and a second leg coupled to the first leg. The first and second legs are separable for placement around the electrode and resiliently return to a clamped position. Each of the first and second legs generally defines a respective longitudinal axis. Each of the first and second legs defines a blade portion offset from the respective longitudinal axis for clamping the electrode.
