Abstract
A surgical device for displacement of organs within a body cavity for providing at least visual access to a selected site includes an expandable bladder, wherein the elasticity of the bladder varies across the surface of the bladder, said variation in elasticity selected to provide a predetermined, non-spherical shape when expanded; and a valve on the proximal end on the inflatable bladder for introduction of a pressurizing gas into the soft bladder.
