  • Patent number: 10669613
    Abstract: A titanium alloy includes 15 to 27 atomic % (at %) of tantalum (Ta) and 0 to 8 at % of tin (Sn), the balance being titanium (Ti) and unavoidable impurities, when the entire 5 amount of the titanium alloy is taken as 100 at %. Therefore, the titanium alloy provided has characteristics suitable for medical device materials, biocompatible materials, etc.

  • Patent number: 10583217
    Abstract: There is provided an implant that is safe for the living body. An angular plate as the implant includes a bone supporting plate part and a blade part. The blade part is integrally formed with the bone supporting plate part, and extends from one end of the bone supporting plate part at a predetermined angle ? (0°<?<180°) relative to the bone supporting plate part. The angular plate is formed from a titanium-tantalum-based alloy containing tin. The angular plate is preferably formed from a titanium-tantalum-based alloy containing tin in which a Young's modulus is decreased by increasing the reduction ratio thereof.

  • Publication number: 20190358021
    Abstract: A medical member of the present invention includes a knitted body knitted with a linear member formed in a linear shape, at least a part of the knitted body is constituted of an alloy containing titanium, tantalum, and tin, and the alloy is constituted of 15 at % to 27 at % of tantalum and 1 at % to 8 at % of tin, where the total is 100 at %, with remainder being titanium and unavoidable impurities. The knitted body is formed in a sheet shape by plain weaving, twilled weaving, plain dutch weaving, twilled dutch weaving, or stockinette stitch. Thus, there can be provided a medical member capable of dispersing a load applied to a treating site of a soft tissue.
