Abstract: An adjustable gel filled mammary implant includes inner and outer envelopes with the outer envelope containing about 95% of its volume filled with a silicone gel or the like. The inner envelope is attached to a bottom portion of the outer envelope and defines a volume of about 5%–10% of the volume of the outer envelope and is filled with saline. The implant also includes a self-sealing valve, filling tube and mini-reservoir for adjusting the size of the implant. A method for implanting, adjusting the size and removal of the filling tube and mini-reservoir are also disclosed.
