1. A surgical system, comprising:

  • a cannula having a proximal end and a distal end;

    a flexible fabric adapted to support tissue, the fabric disposed within the cannula;

    a deployment member permanently coupled to the flexible fabric and adapted to allow the fabric to be pulled through a port, the deployment member being coupled to the flexible fabric at a substantially central midpoint thereof, and the deployment member extending from the distal end of the cannula such that the deployment member can be pulled distally to advance the fabric out of the distal end of the cannula to allow the fabric to support tissue; and

    at least one grasping element coupled to a perimeter of the flexible fabric and adapted to be manipulated to move the flexible fabric and thereby move the tissue, the at least one grasping element extending from the proximal end of the cannula such that the at least one grasping element can be manipulated when the fabric is advanced distally from the cannula to move tissue supported by the fabric.
