Abstract
A method for retracting an organ inside the body in the course of treating adjacent tissue. An inflatable retractor is provided. The inflatable retractor includes a flexible wall which may be expanded into place within the body, and which enclosed a main chamber. The inflatable retractor also includes an envelope attached to the flexible wall. The envelope and part of the flexible wall enclose an additional chamber. The inflatable retractor is placed in a collapsed state adjacent to the organ, and is inflated to expand the flexible wall and to retract the organ. Finally, an aperture is pierced in a part of the flexible wall of the retractor remote from the additional chamber to provide access to the tissue.
