1. A prosthetic implant comprising:
- a first flexible membrane defining a first closed compartment;
a second flexible membrane, spaced inwardly from the first membrane and enclosing a second closed compartment which is contained within the first compartment, the second compartment being filled with a continuously-adjustable amount of bio-compatible fluid; and
a distinctive intermediate unit, disposed within a peripheral space defined between the first and second membranes, the unit comprising individual closed microcapsules each containing a small closed volume of less than 1 cc of bio-compatible fluid.

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.

12. An implantable mammary prosthesis comprising:
-
a first flexible silicone membrane defining a first closed compartment; a second flexible membrane having an upper hemisphere with a thick silicone film punchable and self-sealing and a lower hemisphere made of extensible silicone film adapted to distend the shape of the implant, the second membrane being spaced inwardly from the first membrane and enclosing a second compartment which is contained within the first compartment, the second compartment being filled with a continuously-adjustable amount of physiological salt solution; and a distinctive intermediate unit, disposed within a peripheral space defined between the first and second membranes, the unit being filled with individual closed microcapsules each containing a small closed volume of less than 1 cc of physiological salt solution and being glued together with a silicone adhesive.
