Systems and methods for performing spine surgery
First Claim
1. A sequential dilation system for accessing a spinal target site, comprising:
- an initial dilator including a cannulated body having a longitudinal axis, a tapered distal end, a proximal end, a length such that said proximal end extends beyond a skin surface when said distal end is positioned adjacent to said spinal target site, the initial dilator also including an integrated needle having a distal end configured for penetration into the spinal target site, the integrated needle being spring biased to a first position in which the distal end is contained within the cannulated body and deployable to a second position in which the distal end extends from the tapered distal end of the cannulated body; and
at least one additional dilator slidable to the spinal target site over the initial dilator.

Abstract
This disclosure describes example an surgical fixation system and example methods for implanting the surgical fixation system on the spine. The surgical fixation system can be applied minimally invasively to the anterior column for both single level and multi-level constructs. The surgical system can be applied to the anterior column via lateral access approaches. The lateral access approach may traverse the psoas muscle. The fixation system includes a plurality of anchor assemblies connected by a spinal rod. The anchor assemblies each include a fixation body, bone anchor, rod-receiving member, anchor lock and rod lock. The rod-receiving member may be moveably coupled to the fixation body to facilitate rod insertion.

16. A dilator for forming a path to a spinal target site via a trans-psoas approach, comprising:
a cannulated body having a longitudinal axis, a tapered distal end, a proximal end, a length such that said proximal end extends beyond a skin surface when said distal end is positioned adjacent to said spinal target site, the dilator being insulated along the entire length with the exception of at least one exposed electrical contact at said proximal end and an exposed stimulation electrode at said distal end, an integrated needle traversing the cannulated body having a distal end configured for penetration into the spinal target site, the integrated needle being biased to a first position in which the distal end is contained within the cannulated body and deployable to a second position in which the distal end extends from the tapered distal end of the cannulated body. - View Dependent Claims (17, 18, 19)
