  • Controlled porosity 3-D fabric breast prosthesis
    Patent number: 6432138
    Abstract: A biocompatable nonbiodegradable breast prosthesis comprises a generally conical shell filled with a resilient mass comprised of a multiplicity of layers of resiliently compressible fabric. The shell fabric provides a pore size in the range of from about 2 to 15 microns, 5 microns being preferred. The filler fabric layers define a void content from 70 to 90% or more and are resilient when subjected to compressive forces in both wet and dry conditions. The layers preferably are a honeycomb weave and are formed of monofilament yarns.
