Abstract
An implantable mammary prosthesis designed to combat the formation around it of a retractile shell in reaction to a foreign body comprises a pocket with a front wall that can be inflated to a dome shape by injecting a physiological serum through a valve. The pocket is attached to a back wall to a sheet which is generally oval-shaped symmetrically relative to a major axis. The pocket is placed on the sheet so as to be spaced from the edges thereof on all sides by a distance of at least one fifth the radius of the pocket. The inside edge of the sheet, meaning that to be placed nearest the sternum, is narrower than the outside edge. The sheet is designed to impede retraction of the fibrous shell by creating a reflection line which breaks the continuity of curvature of the shell, so that the latter loses its retractile potential.
