An instrument (10) and a method for retracting or repositioning a distal anatomic structure having a lumen by remote manipulation. The method includes advancing the distal end of a flexible variform intraluminal member (125) in a linear shape through a lumen in the body to a distal location, and deforming the distal end of the instrument to a rigid articulated shape which retracts tissue surrounding the lumen. Further axial or rotational manipulation of a handle (35) attached to the member correspondingly further retracts the distal anatomic structure to facilitate an endoscopic surgery.
