Patent number: 12276017Abstract: Multi-layer metal or pseudometallic materials having engineered anisotropy are disclosed. The multi-layer materials having defined engineered grain orientations in each layer of the multi-layer material and bond layers between adjacent layers orthogonal to the grain orientations. This configuration distributes applied stress across the plurality of layers in the multi-layer metal material and around a neutral axis of the multi-layer metal material and increases the overall mechanical properties of the disclosed multi-layer metal material relative to conventional wrought metal materials of the same or similar chemical constitution. The microstructure of each layer, group of layers, or across multiple layers may be tailored to the intended application of a device made from the material. Individual layers may be tuned for property variations, such as gradients, or to adjust the bond layer characteristics.Type: GrantFiled: May 21, 2021Date of Patent: April 15, 2025Assignee: VACTRONIX SCIENTIFIC, LLCInventors: Scott P. Carpenter, Tianzong Xu, Harshal Surangalikar

Publication number: 20250092506Abstract: Ternary and quaternary shape memory alloys, particularly nickel-titanium based quaternary and quaternary shape memory alloys, are disclosed and made by a method employing physical vapor deposition (PVD), such as by sputtering, of NiTiX, wherein X is a ternary metal constituent. By employing PVD processing, ternary and quaternary NiTi alloy bulk materials may be made in in the as-deposited state such that the configuration and conformation of a desired precursor material, e.g., wires, tubes, planar materials, curvilinear, or as the near finished end product, such as a hypotube for stent manufacture, semilunar for cardiac valves or conical for embolic or caval filters, is formed on a removable deposition substrate in the configuration and conformation of the precursor material or near-finished end product.Type: ApplicationFiled: September 17, 2024Publication date: March 20, 2025Applicant: Vactronix Scientific, LLCInventor: Scott P.

Patent number: 12239555Abstract: A stent for vascular interventions having a hybrid open cell geometry. Variants of the stent include bare metal stents and drug-eluting stents. Embodiments of the stent include end projections for radiopaque markers or a discontinuous partial radiopaque coating on low-stress or low-strain regions of the peripheral stent. The stents of the invention are characterized by having thin walls, nested rows of struts, high expansion ratio, high and uniform radial force over entire diametric size and length of device, crush resistance up to and including about 90% of its fully expanded diameter, high fatigue resistance and high corrosion resistance.Type: GrantFiled: July 12, 2021Date of Patent: March 4, 2025Assignee: Vactronix Scientific, LLCInventors: Scott P. Carpenter, Julio C. Palmaz
