  • Patent number: 8084428
    Abstract: A method of repairing a meniscal tear of a subject includes providing a sheet of collagen membrane material having on one side thereof a smooth barrier face which inhibits cell adhesion thereon and inhibits passage of cells therethrough. The sheet has a fibrous face opposite the smooth barrier face, the fibrous face allowing cell growth thereon. The collagen is predominantly collagen I. The sheet of collagen membrane material is fixed over a meniscal tear so that the fibrous face is oriented toward the meniscal tear.
    Type: Grant
    Filed: September 1, 2006
    Date of Patent: December 27, 2011

  • Patent number: 6080412
    Abstract: A method of producing a microencapsulated pharmaceutical formulation is disclosed comprising causing a dye to be attached to the surface of pharmaceutical particles or particle clusters and applying a source of radiant energy to the dye in the presence of a liquid polymeric or polymerisable material so as to cause the material to cross-link, producing a conformal layer of cross-linked polymer on the particulate surfaces. Preferably, the polymer provides an immuno-protective layer around the particles, while allowing therapeutic components to exit the microcapsules. Microencapsulated pharmaceutical formulations and their medical use are also disclosed, especially for the treatment of diabetes by encapsulating insulin secreting cells.
