Patent ID: 7722552

Claim:
A guide wire comprising: a core member comprising a distal end side portion and a proximal end side portion, the distal end side portion being located on a distal side of the proximal end side portion; a coil covering at least the distal end side portion of said core member; a coil fixing member constituting a metallic member that is separate from said core member and said coil, said coil fixing member being not a brazed joint and being connected to said distal end side portion of said core member at a point where the coil fixing member directly overlies the core member to connect said coil concentrically with said core member at least at a portion in the longitudinal direction of said coil, and said coil being fixed to said coil fixing member by an adhesion material, wherein said coil comprises a distal end side coil and a proximal end side coil, and said coil fixing member connects a proximal end portion of said distal end side coil and a distalmost end portion of said proximal end side coil to said core member, wherein said distal end side coil and said proximal end side coil have different inside diameters, and wherein an outside diameter of said distal end side portion of said core member decreases toward a distal end of said guide wire, said coil fixing member is a tubular body having a lumen, and an inside diameter of said lumen of said coil fixing member decreases toward the distal end following a shape of said distal end side portion.
