  • Methods and apparatuses for forming metal oxide nanostructures
    Patent number: 11643743
    Abstract: Embodiments of methods and apparatuses for forming the metal oxide nanostructure on surfaces are disclosed. In certain embodiments, the nanostructures can be formed on a substrate made of a nickel titanium alloy, resulting in a nanostructure that can include both titanium oxide and nickel oxide. The nanostructure can be formed on the surface(s) of an implantable medical device, such as a stent.
    Type: Grant

  • Devices, systems and methods for coating surfaces
    Patent number: 9903035
    Abstract: The present disclosure provides devices, systems and methods with applicability in the coating of surfaces, in particular three-dimensional surfaces, via anodization reactions. For example, the disclosed devices, systems and methods find use in the formation of microstructured or nanostructured layers, e.g., metal oxide microstructured or nanostructured layers, via anodization on a variety of devices including, e.g., medical devices. Devices modified with one or more microstructured or nanostructured layers are also provided.
