Abstract:
The invention now summarized here is directed toward a surgical device that enables utilization of the lateral approach to the spine with the ability to retract tissue in an anterior-to-posterior direction. The invention also incorporates a surgical method for utilization of the above-mentioned surgical device, embodiments of which incorporate steps for approaching the anterior portion of the disc space, retracting soft tissue in a generally posterior direction, removing disc material, placing a bone graft and removing the associated instrumentation.

Claim (Index 1):
A system for forming an operating corridor to a lumbar spine, comprising:\n an elongate member deliverable to a spinal disc along a lateral path to the lumbar spine; a dilator system to create a distraction corridor along the lateral path to the lumbar spine, the dilator system comprising at least one dilator cannula that slidably engages an exterior of the elongate member, the at least one dilator being deliverable to the spinal disc along the lateral path to the lumbar spine; a multi-bladed retractor assembly slidable over the dilator system toward the spinal disc along the lateral path, the multi-bladed retractor assembly including: a curved stationary arm engaging a stationary retractor blade that extends generally perpendicularly relative to the curved stationary arm and at least one movable retractor arm engaging a movable retractor blade that extends generally perpendicularly relative to the movable retractor arm, wherein the multi-bladed retractor assembly is adjustable from a closed position in which the stationary and at least one movable retractor blade are adjacent to one another and slidable over the dilator system to an opened position in which the at least one movable retractor blade is moved away from the stationary retractor blade to enlarge the distraction corridor and thereby form an operative corridor along the lateral to the lumbar spine, wherein the stationary retractor blade is deliverable to the anterior aspect of the spinal disc, wherein the at least one movable retractor blade is initially adjustable from a closed position in a posterior trajectory relative to the stationary retractor blade delivered to the anterior aspect of the spinal disc, and wherein when the multi-bladed retractor assembly is adjusted to the opened position to form the operative corridor along the lateral path to the lumbar spine, such that the at least one movable retractor blade is positioned to open the operative corridor to a dimension so as to pass an implant through the operative corridor and into the lumbar spine.
