1. Implantable mammary prosthesis adapted to combat the formation around it of a retractile shell in reaction to a foreign body, comprising a flexible pocket having a generally circular base, made from a surgical grade biocompatible film material and being dome shaped when filled with an appropriate fluid, and a substantially flat flexible sheet of surgical grade biocompatible film material, said circular base being integral with said flexible sheet, a base perimeter being defined on the flexible sheet at the perimeter of the circular base;

  • wherein the improvement comprises a flexible peripheral flange formed by the flexible sheet extending continuously circumferentially around the base perimeter and extending outwardly therefrom a distance equal to at least one fifth the radius of said circular base, whereby said flexible periphery flange prevents fibrous membrane from causing capsular contraction about said mammary prosthesis.
