  • Publication number: 20110009955
    Abstract: The invention concerns oligosaccharides and polysaccharides as well as the use of these oligosaccharides and/or polysaccharides, which contain the sugar unit N-acylglucosamine or N-acylgalactosamine for the production of hemocompatible surfaces as well as methods for the hemocompatible coating of surfaces with said oligosaccharides and/or polysaccharides, which imitate the common biosynthetic precursor substance of heparin, heparan sulphates and chitosan. The invention further describes methods for producing said oligosaccharides and/or polysaccharides and discloses various possibilities of using hemocompatibly coated surfaces. The invention relates particularly to the use of said oligosaccharides and/or polysaccharides on stents with at least one according to invention deposited hemocompatible coating, which contains an antiproliferative, antiinflammatory and/or antithrombotic active agent, methods for the preparation of said stents as well as the use of said stents for the prevention of restenosis.

  • Publication number: 20080199506
    Abstract: The present invention relates to methods for coating the entire surface of lattice-like or mesh-like endoprostheses, wherein the endoprostheses initially are being provided with a thin layer covering the material surface of the endoprosthesis and subsequently, the surface of the entire endoprosthesis is being coated, wherein said coating of the entire surface covers the struts as well as the interstices between the individual struts.

  • Publication number: 20080038307
    Abstract: The invention relates to medical products having a surface that is at least partially covered by a polymer layer. Said polymer layer is preferably formed by auto-polymerization. Substances containing least one multiple bond, especially unsaturated fatty acids comprising an alkyl chain consisting of preferably between 7 and 50 carbon atoms are polymerized. Other substances which do not participate in the polymerization can be added to the substances participating in the polymerization reaction. Said substances are preferably saturated fatty acids and fatty acid derivatives. The invention also relates to methods for producing such medical products, and to the use of the same.
