ABSTRACT:
The present invention provides a retractor for providing surgical access through a passage in a patient's body, together with a delivery device for positioning the retractor in the patient's body. The retractor comprises an anchoring frame having an upper surface, a lower surface, and an opening therethrough which defines an axial axis. A flexible tensioning member is attached to the frame, and is extendable from the frame out of the body through the passage when the frame is positioned through the passage and into a body cavity. The retractor is held by the delivery device in a collapsed orientation for placement in the patient's body. The delivery device is released from the retractor to allow the retractor to assume an expanded orientation in the patient's body. This tensioning member is selectively tensionable to spread the tissue radially outwardly from the axial axis.
