  • Implantable device with improved surface characteristics
    Patent number: 8874234
    Abstract: An implantable device comprises a polymer structure having an outer surface facing a surrounding tissue when the implantable device is implanted in a subject body. At least a portion of the surface of the structure has a semi-random pattern of extending micropillars. The semi-random pattern of micropillars on the surface contributes to advantageous surface characteristics of the implantable device in terms of reducing adhesion viable cells to the implantable device as compared to regular patterns of micropillars.
    Type: Grant

  • IMPLANTABLE DEVICE WITH IMPROVED SURFACE CHARACTERISTICS
    Publication number: 20140018893
    Abstract: An implantable device (1) comprises a polymer structure (40) having an outer surface facing a surrounding tissue when the implantable device (1) is implanted in a subject body. At least a portion of the surface of the structure (40) has a semi-random pattern of extending micropillars (50). The semi-random pattern of micropillars (50) on the surface contributes to advantageous surface characteristics of the implantable device (1) in terms of reducing adhesion viable cells to the implantable device (1) as compared to regular patterns of micropillars (50).
