The retractor further includes a first aperture formed at first angular position in the enclosure, and a second aperture formed at second angular position in the enclosure and opposing the first aperture to form a passage extending transverse to the axis from the first aperture, through the lumen, and to the second aperture. The first aperture and the second aperture are located proximate to the first open end and sized to arrange the passage along a spine of a patient to receive a trocar for delivering a graft material to the spine.
