    摘要: A bioerodible endoprosthesis includes a composite including a matrix comprising a bioerodible magnesium alloy and a plurality of ceramic nanoparticles within the matrix. The bioerodible magnesium alloy has a microstructure including equiaxed Mg-rich solid solution-phase grains having an average grain diameter of less than or equal to 5 microns. The microstructure can be produced by one or more equal-channel high-strain processes.

    摘要: A medical implant includes a metal composite that contains a cellular nanomatrix having a metallic nanomatrix material and a metal matrix disposed in the cellular nanomatrix, the medical implant being configured to disintegrate in response to contact with a fluid. A method for repairing tissue includes disposing an implant in a patient, the implant including a metal composite which contains: a cellular nanomatrix having a metallic nanomatrix material; and a metal matrix disposed in the cellular nanomatrix; contacting tissue of the patient with the implant, the tissue being in need of repair; and non-operatively removing the implant to repair the tissue.

    摘要: A titanium based, ceramic reinforced alloy ingot for use in producing medical implants. An ingot is formed from an alloy having comprising from about 5 to about 35 wt. % niobium, from about 0.5 to about 3.5 wt. % silicon, and from about 61.5 to about 94.5 wt. % of titanium. The alloy has a hexagonal crystal lattice α phase of from about 20 vol % to about 70 vol %, and a cubic body centered β crystal lattice phase of from about 30 vol. % to about 80 vol. %. The ingot has an ultimate tensile strength of about 940 MPa or more, and a Young's modulus of about 150 GPa or less. A molten substantially uniform admixture of a niobium, silicon, and titanium alloy is formed, cast into a shape, and cooled into an ingot. The ingot may then be formed into a medical implant and optionally annealed.
