Guide wire devices and other intra-corporal medical devices fabricated from a Ni-Ti-Nb alloy and methods for their manufacture. The Ni-Ti alloy includes nickel, titanium, and niobium either up to its solubility limit in Ni-Ti, or in amounts over 15 atomic percent so as to provide a dual phase alloy. In either case, the Ni-Ti-Nb alloy provides increased stiffness to provide better torque response, steerability, stent scaffolding strength, and similar properties associated with increased stiffness, while still providing super-elastic or linear pseudo-elastic properties. |
