Abstract
Abstract A COMPOUND PROSTHESIS FOR SURGICAL IMPLANTATION IS PROVIDED WITH INTERNAL PARTITIONS THAT DIVIDE THE HOLLOW CONTAINER INTO A PLURALITY OF INTERNAL COMPARTMENTS. EACH OF THE COMPARTMENTS IS SUBSTANTIALLY FILLED WITH A SOFT FLUID GEL WHICH ALLOWS THE PROSTHESIS TO CHANGE SHAPE READILY, BUT THE COMPARTMENTALIZATION MINIMIZES ANY VISIBLE CHANGE IN SHAPE DUE TO MOVEMENTS OF THE WEARER.
