1. A system including an inflatable means for use in cosmetic surgery to expand an initial cavity into a predetermined region of fatty-tissue cleavage extending transverse to the initial cavity to form a final cavity, the system comprising:

  • an elongate means having spaced proximal and distal ends and adapted at its proximal end to receive an inflation fluid and having at least one port at a location distal to the proximal end for supplying inflation fluid to the inflatable means;

    the inflatable means comprising two like panels of pliant but essentially non-stretch material conforming generally to a predetermined region within a fatty-tissue cleavage and secured to the elongate means along a longitudinal alignment distal with respect to the proximal end and otherwise peripherally secured to each other, such that the port is in communication with the inflatable means;

    the inflatable means being capable of initially being in an uninflated state wherein the inflatable means is precoiled and operatively connected to the elongate means;

    whereby, upon insertion of the system into the initial cavity, the inflatable means is capable of conforming to an inflated state, wherein in the inflated state, the inflatable means is capable of expanding within a fatty-tissue and throughout an area within a fatty-tissue which is laterally offset with respect to the system such that when the inflatable means is inflated, the inflatable means deploys in a pattern that permits the inflatable means to remain in the initial plane within a fatty-tissue to form a final cavity within a fatty-tissue which conforms substantially to the predetermined region.
