A device for inserting a support beneath an object is provided that includes an eversible tubular membrane with a closed end and an open end with the open end sealably connected to a container enclosing a pressurized fluid, wherein the closed end is connected such that it can be retracted under tension through the inside of the tube formed by the radially outward facing aspect of the membrane, and wherein with pressure and/or tension changes the membrane can be eversibly extended and retracted between two surfaces. In addition, the membrane may be co-everted with a sling or draw sheet such that the sling or draw sheet can be inserted between two surfaces along with the membrane. Further, multiple eversible membranes may be inserted between two surfaces or beneath an object or a patient in accordance with the disclosed invention.
