Summary:A system for accessing a surgical target site comprises a trans-psoas dilator system, a three-bladed tissue retraction assembly and a spinal fusion implant. The three-bladed tissue 5 retraction assembly maintains the tissue distraction corridor along the lateral, trans-psoas path and comprises a caudal-most retractor blade, a cephalad-most retractor blade, a posterior-most retractor blade, a first retractor arm having comprising a first blade connecting portion connectable to the proximal end of the caudal-most retractor blade, a second retractor arm comprising a second blade connecting portion connectable to the proximal end of the 10 cephalad-most retractor blade; a translating member being translatable in response to rotation of an actuating member and comprising a third blade connecting portion connectable to the proximal end of the posterior-most retractor blade; and a coupling mechanism hingedly connecting the first pivot portion of the first retractor arm and the second pivot portion of the second retractor arm such that the first retractor arm is pivotable with respect to the second 15 retractor arm about an axis that extends through the translating member. The spinal fusion implant is sized and shaped to insert between the retractor blades along the trans-psoas path and into the targeted intervertebral disc of the lumbar spine while the retractor blades maintain the tissue-distraction corridor along the trans-psoas path.
