Intraluminal guide wires including at least a portion thereof fabricated from a non-super-elastic cobalt-chromium alloy that exhibits improved elasticity, while maintaining a relatively high yield strength, as compared to conventionally employed non-super-elastic cobalt-chromium alloys. The guide wire may include an elongate core wire having a distal end and a proximal end, wherein at least a portion of the elongate core wire is fabricated from a cobalt-chromium alloy having a Youngs modulus that is 150 GPa or less while having a yield strength that is at least 280 ksi.
