Abstract
An inflatable retractor including a main envelope enclosing a main chamber is provided. The main envelope is provided in a collapsed state. An elastomeric window is also provided. The main envelope of the inflatable retractor is placed adjacent the organ inside the body, and the main chamber is expanded to an expanded state to retract the organ. Following inflation of the main chamber to the expanded state, the elastomeric window is attached to the main envelope inside the main chamber to cover part of the main envelope. The surgical instrument is passed into the main chamber. An aperture is pierced in the pan of the main envelope covered by the elastomeric window to provide access for the surgical instrument to contact the tissue. The elastomeric window provides a gas-tight seal to maintain the main chamber in the expanded state.
