  • Patent number: 11608565
    Abstract: Embodiments of nanostructures comprising metal oxide and methods for forming the 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 containing both titanium oxide and nickel oxide. The nanostructure can include a lattice layer disposed on top of a nanotube layer. The distal surface of the lattice layer can have a titanium oxide to nickel oxide ratio of greater than 10:1, or about 17:1, resulting in a nanostructure that promotes human endothelial cell migration and proliferation at the interface between the lattice layer and human cells or tissue. The nanostructure may be formed on the outer surface of an implantable medical device, such a stent or an orthopedic implant (e.g. knee implant, bone screw, or bone staple).

  • Patent number: 9216029
    Abstract: This application presents a bifurcated, optimally-angled surgical forceps. In one example, this surgical forceps may enable a more natural maneuver for initial clamping of the vas deferens through the scrotal skin. This may be more comfortable for users and easier to maintain, and may provide greater tactile surface contact between the thumb and vas deferens. This device also may provide the surgeon with an entire segment of vas deferens upon which the vasectomy may be performed, thus reducing the need for frequent repositioning of instruments. The device may also be applied to other surgical procedures that may benefit from the features of the device and where a section of a tubular anatomical structure may need clamping at two points along its length. Examples include blood and lymphatic vessels, ducts of the digestive system, and large nerves or nerve bundles.
