Abstract
Abstract An apparatus for retracting an organ inside the body to gain access to an adjacent tissue includes a main chamber which is positionable within the body and inflatable to an expanded condition to retract a body organ. The apparatus includes an inflatable additional chamber which when inflated maintains the main chamber in the expanded condition, and the organ in the retracted condition, notwithstanding release of the main chamber from the inflated condition.
