Shapeable guide wire devices and methods for their manufacture. Guide wire devices include an elongate shaft member having a shapeable distal end section that is formed from a linear pseudoelastic nickel-titanium (Ni&#x2014;Ti) alloy that has linear pseudoelastic behavior without a phase transformation or onset of stress-induced martensite. Linear pseudoelastic Ni&#x2014;Ti alloy, which is distinct from non-linear pseudoelastic (i.e., superelastic) Ni&#x2014;Ti alloy, is highly durable, corrosion resistant, and has high stiffness. The shapeable distal end section is shapeable by a user to facilitate guiding the guide wire through tortuous anatomy. In addition, linear pseudoelastic Ni&#x2014;Ti alloy is more durable tip material than other shapeable tip materials such as stainless steel.

A guide wire for use in a medical procedure having a shapeable tip integral with and made from the distal end of a superelastic nitinol distal section of the guide wire, wherein the shapeable tip can be finger kinked. Such a guide wire includes an elongated core made from a superelastic nitinol alloy at the distal end, the distal end of the elongated core having a tapered section leading to a shapeable distal tip. The shapeable tip is an extension of the distal end of the nitinol distal section, and includes permanent strain hardening from at least two different radial directions imparting crystallographic texture in the radial directions that eliminate superelasticity so that permanent deformation can be achieved with finger pressure.
