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