  • Patent number: 11857700
    Abstract: Polymer devices are disclosed with microstructured surfaces that modify their absorption pathway. Polymers which generally degrade in water by fracturing into high surface energy fragments, are modified to degrade in vivo without the formation of sharp fragments. Devices are disclosed that possess improved handling characteristics and degrade in an aqueous environment in a uniform and continuous way that favors the formation of soluble monomers rather than solid particulate. Absorbable medical implants with the disclosed surface modifications are more biocompatible, with reduced foreign body response, and dissolution into metabolizable molecular species.
    Type: Grant
    Filed: February 12, 2021
    Date of Patent: January 2, 2024
    Assignee: BVW Holding AG
    Inventors: Lukas Bluecher, Kenneth Kleinhenz, Michael Milbocker

  • Publication number: 20080063686
    Abstract: Resorbable lactide polymer thin membranes are disclosed. The thin membranes are constructed of polylactide resorbable polymers, which are engineered to be absorbed into the body relatively slowly over time in order to reduce potential negative side effects. The membranes are formed to have very thin thicknesses, for example, thicknesses between about 0.010 mm and about 0.300 mm. The membranes can be extruded from polylactide polymers having a relatively high viscosity property, can be preshaped with relatively thick portions, and can be stored in sterile packages.

  • Publication number: 20050036945
    Abstract: A resorbable medical implant is disclosed that includes one or more resorbable radiopaque markers. The resorbable radiopaque markers permit visualization of the location of the implant in a patient while reducing obstruction of tissue changes occurring in proximity to the implant. The resorbable radiopaque markers may include non-metallic and/or non-bone derived materials.
