  • Patent number: 9044225
    Abstract: A self-retaining suture comprises a composite filament. The filament has retainers on the surface such that the filament can engage and retain tissue without knots. The filament comprises at least two materials having different properties. A surface material of the filament has properties which enhance the formation, elevation and/or deployment of the retainers. A core material of the filament has properties which enhance the tensile strength of the filament. The surgical filament is thin and flexible and may be used for suturing. Methods for manufacturing the filament and retainers are also described.

    Abstract: A thermoplastic composition that is water-sensitive (e.g., water-soluble, water-dispersible, etc.) in that it loses its integrity over time in the presence of water that can also be injection molded is provided. The composition contains a cellulose derivative, a synthetic water-soluble polymer, and a plasticizer. The desired water-sensitive and moldable attributes of the composition may be achieved in the present invention by selectively controlling a variety of aspects of the composition, such as the nature of the components employed, the relative amount of each component, the manner in which the composition is formed, and so forth.

  • Patent number: 8986594
    Abstract: The present invention relates to metal coated nano-fibres obtained by a process that includes electrospinning and to the use of said metal coated nano-fibres. The process is characterised in that a polymer nano-fibre with functional groups providing the binding ability to a reducing reagent is prepared by electrospinning at ambient conditions. Then this is contacted with a reducing agent, thereby opening the epoxy ring on the surface of polymer nano-fibre and replacing with the reducing agent and the reducing agent modified film is reacted with metal solution in alkaline media. Finally the electrospun mat is treated with water to open the epoxy rings in the structure and crosslinking the chains to provide integrity.
