Patent ID: 8360996

Claim:
A guide wire comprising: a wire main body having flexibility; a reshapeable wire material separate and distinct from said wire main body and having a portion, on a proximal end side, secured to a distal end side of the wire main body and overlapping a portion of the wire main body, and an extending portion, at a portion on a distal end side, extending in a distal end direction from the distal end side of the wire main body; and a coil installed to cover the distal end side of the wire man body and the wire material, the coil being obtained by helically forming a raw-wire; wherein a bending rigidity of the coil per se of a distal end side portion located at a position corresponding to the extending portion is higher than a bending rigidity of the coil per se of a proximal end side portion located at a position corresponding to the portion overlapping the portion of the wire main body and closer to the proximal end side than the distal end side portion; wherein the guide wire in the extending portion has a first area, a second area, and a third area; the first area is located distally of the third area and the second area is located between the first area and the third area, a bending rigidity of the entire guide wire at the third area is higher than a bending rigidity of the entire guide wire at the first area, and a bending rigidity of the entire guide wire at the second area is gradually reduced toward the distal end side from the proximal end side; and wherein the extending portion extends parallel to a longitudinal axis of the wire main body.
