Abstract

A method of biological reconstruction and a device having a major chamber or compartment in the form of the desired anatomy with a shaped chamber inside the main chamber flipped up and held in place by one or more inflatable piston chambers. The inflatable piston chambers selectively hold the shaped chamber and are pressurized in order to support the shape of the device upon implantation. Valves are provided to allow filling the major chamber, the shaped chamber and the piston chambers with a biologically compatible fluid.
