ABSTRACT:
An inflatable apparatus for organ retraction includes a main envelope which forms a main chamber. An additional chamber is formed by attaching the periphery of an additional envelope to the outside or the inside of the main envelope. The part of the surface of the main envelope that is not covered by the additional envelope provides a plurality of windows, which, after the additional chamber is inflated, may be at least partially removed to provide apertures through which treatment or observation can be carried out.
