Medical guide wire
First Claim
1. A guide wire (10) for guiding a medical device within a body lumen, comprising:
- a proximal section (11) including a proximal wire core (111) formed of a first material and having a proximal end (112) and a distal end (113), said proximal wire core (111) having at least one portion (109) being tapered with contraction towards the proximal end (112) of said proximal wire core (111);
a distal section (12) including a distal wire core (121) formed of a second material and having a proximal end (122) and a distal end (123), said distal wire core (121) having at least one portion being tapered with contraction towards the distal end (123) of said distal wire core (121);
a mid section (13) including a joint (131) joining said distal end (113) of the proximal wire core (111) and said proximal end (122) of the distal wire core (121);
a continuous safety wire (15) extending along the mid section (13), and at least a portion of the proximal section (11) and the distal section (12); and
an outer tubing (14) enveloping said joint (131) and at least parts of the proximal section (11) and the distal sections (12);
wherein in the mid section (13), the proximal wire core (111), the distal wire core (121), and the safety wire (15) in combination form a generally circular cross section of the combined materials of the proximal wire core (111), the distal wire core (121), and the safety wire (15).

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.
