    Abstract: The present invention relates to a composition for cartilaginous tissue repair and to a production method therefor. The present invention comprises the steps of: (a) dissolving freeze-dried fibrinogen in an aprotinin solution; (b) dissolving freeze-dried thrombin in a stabilizing solution; (c) mixing an enriched collagen solution with thrombin and the stabilizing solution; and installing the fibrinogen solution (a) to one side of a dual kit and the solution (c) containing the collagen to the other side, and then mixing and injecting into damaged cartilaginous tissue. In the present invention, which is constituted as described above, biomaterials such as collagen and fibrin are mixed so as to allow damaged cartilaginous tissue to be repaired to a state allowing transplantation onto the tissue, and efficient regeneration is induced, thereby making it possible to reduce surgery-related stress on people and animals while inducing relatively rapid and efficient cartilage repair and regeneration.

  • Patent number: 9006182
    Abstract: A light activated collagen-flavin composite layer incorporating riboflavin is applied as treatment for infected lesions. These composites have also been found to be strong tissue adheives that are effective in closing and sealing wounds, fixation of grafts/ implants and anastomoses. Advantages include speed of closure, reduced infection due to the elimination of foreign matter, evidence of accelerated wound healing and the ease of use in complex surgery, especially when watertight seals, limited access or small repair size are important factors. The riboflavin in the collagen layer is exposed to light (e.g., light having a wavelength between 360-375 nm or 440-480 nm), decomposing the riboflavin to form reactive oxygen species (ROS). Strong crosslinks between the collagen composite and tissue results. In addition, similar exposures eradicate pathogens in the wound.

  • Publication number: 20150080815
    Abstract: A wound dressing makes use of a polysaccharide, such as Manuka honey, in combination with collagen in order to suppress the efficacy of matrix metalloproteinases enzymes (“MMPs”) present in chronic wounds. The mixture is applied to an absorbent surface that is designed to absorb the mixed polysaccharide only partially.

    Abstract: Methods of making a biologically active three-dimensional scaffold capable of supporting growth and differentiation of a cell are described. Biologically active three-dimensional scaffold made by the methods of the invention and an engineered tissue made from the scaffolds are described. Fibers of desired porosity can be obtained from non-structural ECM by lyophilization and/or electrospinning which can be useful for numerous tissue engineering applications requiring complex scaffolds, such as wound healing, artificial skin (burns), soft tissue replacement/repair and spinal cord injury.
