  • A STEERABLE ARM FOR USE IN ENDOSCOPIC SURGICAL PROCEDURES
    Publication number: 20240108422
    Abstract: A steerable arm for use in endoscopic surgical procedures. The steerable arm cut from a tube of nitinol to provide flexibility and resilience by the structure into which the tube is cut. Typically, the cut tube comprises a spiralling coil, the loops of which are in contact on one lateral side of the tube and the tube is bent to open apart the loops on the other lateral side. The material which the tube is made of is capable of retaining memory of the bend. This provides a bias for restoring the tube to the bend whenever a force causing the tube to flex is removed.

  • Method of forming inorganic nanocages
    Patent number: 11325112
    Abstract: Nanocages are formed by etching nanocubes. The nanocubes are added to an aqueous system having an amphiphilic lipid dissolved in an organic solvent (e.g. a hydrophobic alcohol) to form reverse micelles. As the water evaporates the micelles shrink as etching of the flat surface of the nanocubes occurs. In this fashion hollow nanocages are produced. In one embodiment, the nanocage is covalently attached to a polymer shell (e.g. a dextran shell).
