  • RESORBABLE COVERING MEMBRANE FOR MEDICAL WOUND AREA TREATMENT
    Publication number: 20230390453
    Abstract: A covering membrane for medical wound area treatment is disclosed for burns or for preventing adhesion. The covering membrane has a substrate layer including a polymer material as well as collagen particles which have a particle size I of more than 80 ?m and are disposed in such a way as to be fixedly embedded in at least some portions of the polymer material of the substrate layer. The covering membrane further relates to a process for manufacturing such a covering membrane.

  • Bioresorbable nerve guide rail
    Patent number: 7198799
    Abstract: A biologically resorbable nerve guide rail with a microporous guide tube of polymers of hydroxycarboxylic acids, where the porosity allows a metabolism through the tube wall, but prevents the passage of cells, and optionally several monofilaments of polymers of hydroxycarboxylic acids located in the guide tube, is characterized in that the inner surface of the tube and/or the surface of the monofilaments have an orientation aid for longitudinally oriented colonization with Schwann's cells.

  • Medical, bioresorbable implant, process for its production and the use thereof
    Patent number: 6773459
    Abstract: A medical, bioresorbable implant, particularly for cruciate ligament augmentation, is constructed as a composite structure in textile construction from at least two biocompatible polymer materials, which differ in their chemical composition and/or polymer structure and which are degradable, the implant having a predetermined initial tensile stiffness and a different degradation behaviour of the polymers and/or the textile construction is selected in such a way that the tensile stiffness decreases during degradation.
