  • Bulking of Soft Tissue
    Publication number: 20090311328
    Abstract: A soft tissue bulking material includes a plurality of particles. Each particle comprises a rounded polymeric shell defining an internal cavity and having a maximum outer dimension of 50 ?m-250 ?m. A port or opening is provided in the shell. The port or opening thus provides access to the cavity. The port or opening has a size or dimension that ranges from one tenth of the particle's outer dimension up to the particle's outer dimension.

  • Artefact suitable for use as a bone implant
    Patent number: 6280478
    Abstract: A three-dimensional lattice structure for use as a bone implant where bone growth is required. The lattice structure has a plurality of laths or bars of bioactive material. The laths or bars cross each other in a plurality of zones, and are interconnected in these zones forming interstices between the adjacent laths or bars. The interstices define a plurality of interconnected pored or channels in the lattice structure.
