Abstract

See full text

An apparatus for retracting an organ to gain access to treat a tissue. The apparatus has a main envelope, a second envelope, a first inflation device and a second inflation device. The main envelope encloses a main chamber, and includes a window and a removable window. The second envelope covers substantially all the main envelope, except the window and the removable window. The second envelope and the main envelope enclose a second chamber outside the main chamber. The first inflation device passes a fluid into the main chamber to expand the main chamber and the second chamber from a compacted state to retract the organ. The second inflation device passes a fluid into the second chamber to further expand the second chamber to maintain the organ in its retracted state after fluid has been released from the main chamber.
