Kind Code:
A
Abstract:
To provide a guide wire in which a narrow part can be expanded without shaping by an operator.SOLUTION: A guide wire 100 comprises: a long sized core member 110; a lumen body 120 for covering a surrounding of a tip end part of the core member; and a tip end fixing part 131 including a low density material and a high density material whose densities are different each other, being jointed to tip end parts of the lumen body and the core member, and fixing the tip end of the lumen body to the tip end of the core member. The tip end fixing part, a part of the core member jointed to the tip end fixing part, and a part of the lumen body jointed to the tip end fixing part form a tip end chip part 180. A centroid M of the tip end chip part is deviated from a center axis C of the lumen body. When a plane S1 including the center axis and being orthogonal to a perpendicular line L from the centroid to the center axis is a boundary, the tip end chip part has a first region A1 where there is no centroid, and a second region A2 where the centroid is provided. The high density material is included in the second region by a greater amount than an amount in the first region.SELECTED DRAWING: Figure 2
