His work focuses on improving the workability and properties of materials used in medical applications.
Latest Patents
Mizuki Nihei holds 2 patents that showcase his innovative approach to medical alloys. His first patent involves a medical Pt-W alloy that contains 10 mass % or more and 15 mass % or less of tungsten, with the balance being platinum and inevitable impurities. This invention emphasizes the importance of limiting zirconium content to 1000 ppm or less to enhance workability, especially during hot working processes. Additionally, controlling calcium content to 250 ppm or less further improves the material's workability. This alloy is particularly suitable for processing into wires used in embolic coils and guide wires.
His second patent pertains to a medical Pt alloy wire made from a Pt-W alloy that also contains 10% by mass or more and 15% by mass or less of tungsten. This alloy wire exhibits a Vickers hardness of 400 Hv or more and 600 Hv or less, providing superior hardness and strength compared to conventional Pt alloy wires with similar compositions. The properties of this alloy wire make it ideal for use in medical tools such as coils and guide wires, while also ensuring good workability during secondary processing.
