    摘要： A shapeable guide wire device configured to allow a practitioner to shape a distal end to a desired shape for tracking through a patient's vasculature, the shapeable guide wire comprises:
    an elongate shaft member that includes a practitioner-shapeable distal end section formed of a linear pseudoelastic nickel titanium alloy such that the distal end section does not exhibit a phase transformation or onset of stress-induced martensite as the distal end section is stressed, the distal end section having a metallic material applied over the linear pseudoelastic nickel titanium alloy before cold working of the distal end section of the elongate shaft member;
    wherein the practitioner-shapeable distal end section has a yield stress from about 100 ksi to about 300 ksi;
    a helical coil section disposed about at least the practitioner-shapeable distal end section; and
    an atraumatic cap section attached to the helical coil section and the metallic material of the practitioner-shapeable distal end section.
