    Abstract: The present invention is directed to a bioadhesive thermogelling hydrogel composition for repairing and/or augmenting an intervertebral disc. The bioadhesive thermogelling hydrogel composition can be cross linked with the surrounding tissue so as to potentially serve as a nucleus pulposus replacement or augmentation along with serving to repair annular tears or fissure. The bioadhesive thermogelling hydrogel composition may include three main components: a thermal responsive polymer, an amine-containing polymer and a crosslinking component. All three components can be modified and combined in numerous ways to serve the need of the system as long as the amine-containing component is kept separate from the crosslinking component until the components are injected. The incorporation of a two-part crosslinking thermal responsive hydrogel permits smaller amounts of the crosslinking component to be used and enables the crosslinking dialdehyde to be delivered locally into the tissue that will react with the hydrogel.

  • Patent number: 8206782
    Abstract: The present invention describes a process for the surface finishing of materials via application of specific polymethacrylate layers. The polymethacrylate layers are composed of blends of at least two (co)polymers of polymethacrylates, and specific “reactive monomers” are present here in a polymerized mixture which forms the polymethacrylate layer. At the application temperature established, these form a chemical and, where appropriate, also a physical bond to the substrate, and therefore have adhesion-promoting action.
