Claim Text:
1. A medical device, comprising: a body; at least a portion of the body being fabricated from a nickel-titanium (Ni—Ti) alloy comprising nickel (Ni), titanium (Ti), and a ternary alloying element selected from the group consisting of tantalum (Ta), hafnium (Hf), vanadium (V), zirconium (Zr), and combinations thereof, wherein the ternary alloying element is present in the Ni—Ti alloy in an amount ranging from about 4 atomic % (at %) to about 30 at %, wherein the Ni—Ti alloy has a first phase rich in Ni—Ti and a second phase rich in the ternary alloying element, and one or more of: an elastic modulus in an austenite phase of greater than about 85 GPa, an elastic modulus in a martensite phase of greater than about 42 GPa, or a martensite transformation (Ms) temperature of less than about −5° C.; and wherein the first phase and the second phase are arranged in a lamellar structure including elongate bands of the first phase surrounded by elongate bands of the second phase.
