Abstract

An implantable prosthesis comprised of a solid elastomer made from a synthetic organic polymer that is biocompatible, compliant, and has water content greater than 5%. The solid construction prevents leaks and ruptures that are prevalent in other implants. The implant has the look, fit and feel of human tissue from various parts of the body.
