ABSTRACT:
A prosthetic implant comprising a first membrane defining a first compartment and a second membrane, spaced inwardly from the first membrane, defining a second compartment contained within the first compartment. The second compartment is filled with a constantly adjustable amount of fluid. A distinctive unit, situated between the first and second membranes, is filled with a number of individual microcapsules which contain closed volumes smaller than 1 cc of fluid. The microcapsules optionally may be united together by a silicone adhesive. The small volumes avoid leakage of significant amounts of fluid during puncture of the prosthesis to inject or remove fluid subsequent to implantation.
