Abstract
A guide wire for guiding a medical device within a body lumen is described. The guide wire includes a proximal section, a distal section, and a mid section. The proximal section includes a proximal wire core tapered with contraction towards a proximal end of the proximal wire core. The distal section includes a distal wire core tapered with contraction towards a distal end of the distal wire core. The mid section includes a joint for joining the proximal wire core and the distal wire core. The guide wire also includes a safety wire extending along the mid section, and along at least parts of the proximal and distal sections. Moreover, the guide wire includes an outer tubing enveloping the overlapping joint and at least parts of the proximal and distal sections.
