First Claim
1. A pair of retractor blades for maintaining an operative corridor along a lateral, trans-psoas path to a lumbar spine, comprising:
- a first retractor blade configured to be delivered toward a spinal disc along a lateral, trans-psoas path to the lumbar spine, the first retractor blade comprising;
at least one mounting arm configured to receive and lock with a blade holder apparatus, a distal blade portion extending perpendicular to the at least one mounting arm of the first retractor blade and including an interior face and an exterior face, an intermediate portion connecting between the distal blade portion and the at least one mounting arm of the first retractor blade, and one or more stimulation electrodes disposed along the exterior face of the distal blade portion and oriented oppositely away from the exterior face of the distal blade portion; and
a second retractor blade configured to be delivered toward the spinal disc along the lateral, trans-psoas path to the lumbar spine and positioned oppositely from the first retractor blade, the second retractor blade comprising;
at least one mounting arm configured to receive and lock with the blade holder apparatus, a distal blade portion having the same shape and size as the distal blade portion of the first retractor blade, extending perpendicular to the at least one mounting arm of the second retractor blade, and including an interior face and an exterior face, and an intermediate portion connecting between the distal blade portion and the at least one mounting arm of the second retractor blade,wherein the first and second retractor blades are configured to maintain the operative corridor along the lateral, trans-psoas path to the lumbar spine so that the operative corridor is dimensioned so as to pass an implant through the operative corridor along the lateral, trans-psoas path to the lumbar spine.

Abstract
A system for accessing a surgical target site and related methods, involving an initial distraction system for creating an initial distraction corridor, and an assembly capable of distracting from the initial distraction corridor to a secondary distraction corridor and thereafter sequentially receiving a plurality of retractor blades for retracting from the secondary distraction corridor to thereby create an operative corridor to the surgical target site, both of which may be equipped with one or more electrodes for use in detecting the existence of (and optionally the distance and/or direction to) neural structures before, during, and after the establishment of an operative corridor to a surgical target site.
