  • Biocompatible implant system and method
    Patent number: 7942930
    Abstract: The invention relates to an implantable combination comprising a barrier (12), and a macromolecular bio-compatible material (14). The barrier (12) is porous to allow moieties of the macromolecular bio-compatible material (14), when implanted, to be exposed through the barrier, whereby the surface of the barrier is experienced by the body as an essentially non-foreign object. It also relates to an implant made from a barrier material and a bio-compatible material, the implant being suitable as e.g. a breast implant.
