  • Publication number: 20230397955
    Abstract: A method of configuring a bone fixation system for a fracture of a human's long bone shaft, includes determining a fixator reference and a fixator dimension value. Determining the fixator reference is based on at least a bone reference, a fixator parameter, and the fixator dimension value. The fixator dimension value includes a function of a critical load value in accordance with a design formula, the design formula being based on a fracture parameter, a fixator parameter, and a body constraint value. The design formula is determined by searching a formula library. A plurality of design formulas are searchable by the fracture parameter, the fixator parameter, or the body constraint value.

  • Publication number: 20220088675
    Abstract: To provide Ti—Cu alloy formulations and additive manufacturing process configurations for fabrication of a bulk metallic glass (BMG) product that is biocompatible and antimicrobial, compositions of Ti-based metal alloy powder, comprising: Ti; Cu within a range of 5-30 atomic percent; transition metal within a range of 0-50 atomic percent, wherein such transition metal is one or a plurality of Zr, Nb, Ta, Pd, and Co, are disclosed. Moreover, additive manufacturing processes disclosed herein are capable of fabricating a bulk metallic glass of one or a combination of following phasic structures: fully amorphous microstructure; amorphous beta titanium phase; amorphous copper phase; and amorphous (Ti,M)2Cu phase. The resulting biocompatible metal alloy product may be a medical device, particularly but not limited to a medical implant.

  • Patent number: 7947134
    Abstract: Methods and compositions for a novel metal-to-metal or material-to-material joining technique using bulk metallic glasses are provided. The method of the current invention relies on the superior mechanical properties of bulk metallic glasses and/or softening behavior of metallic glasses in the undercooled liquid region of temperature-time process space, enabling joining of a variety of materials at a much lower temperature than typical ranges used for soldering, brazing or welding.
