Tissue retraction devices and methods include a tissue retractor with a radiolucent portion to permit imaging through the radiolucent portion with X-ray, fluoroscopic or other suitable imaging system. The tissue retractor also includes one or more radio-opaque elements that define at least a portion of a perimeter of the radiolucent portion to provide an indication of the retractor location in the patient via the imaging system.
