Abstract
In a method for retracting an organ inside the body to provide access for treating a tissue, a retractor having a main envelope which defines a main chamber is positioned in a collapsed state adjacent to the organ to be retracted. The main chamber is subsequently inflated to retract the adjacent organ. A surgical instrument is passed through the main envelope into the main chamber to contact the tissue for treatment.
