Abstract
A mammary prosthesis comprising an envelope of an inert elastomer for containing an inert fluid material. The envelope is composed of a plurality of firm protuberances distributed substantially equally thereover. These protuberances may be platelike, ridges, tubes, or posts. The protuberances may be in one or more layers and may be covered with an outer envelope of inert elastomer which may be perforated or in the form of a web. The protuberances provide therebetween flow spaces such that when the scar capsule contracts and compresses the protuberances, the mammary prosthesis will have a space for displacement and remain soft. The protuberances further provide greater localized pressure in pounds per square inch against the scar capsule for a given amount of massage exercise done after surgery. Since scar stretches in response to pressure, this reduces the amount of scar contracture of the capsule.
