Abstract
According to some embodiments, a retractor device for selectively moving (e.g., retracting) anatomical tissue of a subject during a minimally invasive procedure (e.g., accessing the lumbar or other portion of a spine during a spinal fusion procedure) comprises a main body comprising at least three sides (e.g., three, four, five sides, more than five sides, etc.). In some embodiments, the main body defines or otherwise forms a central opening, which comprises a center-point positioned along a centerline of the central opening. In some embodiments, the retractor device further comprises a plurality of movable members secured to the main body.
