Abstract
Apparatus for retracting an organ inside the body to gain access to an adjacent tissue. The apparatus comprises an expandable cage and an expansion element. The expandable cage is capable of being inserted into the body through a small incision or puncture in a collapsed state. The expansion element is for selectively expanding the expansible cage inside the body to an expanded state. The expansion element includes an envelope enclosing a fluid-inflatable chamber. The expansible cage includes an additional envelope mounted inside the inflatable chamber and enclosing an additional fluid-inflatable chamber. The expansible cage is additionally capable of maintaining the expanded state independently of the expansion element after the expansible cage has been expanded by the expansion element to the expanded state.
