Claim:
1. A surgical system for providing a lateral, trans-psoas operative corridor to a lumbar spine, comprising: trans-psoas sequential dilation means for sequential dilation of a lateral, trans-psoas path to a targeted spinal disc of a lumbar spine, and inner means for sliding within said trans-psoas sequential dilation means and for engaging with a lateral aspect of the targeted spinal disc along the lateral, trans-psoas path to the lumbar spine, wherein a distal portion of at least one of said trans-psoas sequential dilation means and inner means includes a means for outputting electrical stimulation for nerve monitoring when the means for outputting electrical stimulation is positioned in the lateral, trans-psoas path; and a trans-psoas retraction means for retracting the dilated lateral, trans-psoas path to provide a trans-psoas operative corridor so dimensioned to pass an implant through the trans-psoas operative corridor along the lateral, trans-psoas path to the lumbar spine, said trans-psoas retraction means comprising: a plurality of means for maintaining the trans-psoas operative corridor along the lateral, trans-psoas path, and a holder means for mating with and retaining positions of the plurality of means for maintaining the trans-psoas operative corridor, wherein at least two of the plurality of means for maintaining the trans-psoas operative corridor are mountable to holder means so as to be caudal-most means for maintaining the trans-psoas operative corridor and acephalad-most means for maintaining the trans-psoas operative corridor.
