Abstract
A prosthesis for subcutaneous implantation such as a mammary implant used in reconstructive surgery is made from a polyphosphazene elastomer (e.g. polyfluoroalkoxy phosphazene) sac containing a silicone gel. The sac is essentially impermeable to the silicone gel fill and overcomes a gel migration problem encountered with implants made using polysiloxane sacs.
