    • A guide wire includes a wire body having a first wire disposed at a distal end and a second wire joined to a proximal end of the first wire at a joint by welding. The joint is curved. In the joint, at least one component (e.g., Ti) of the material of the first wire decreases toward the proximal end and at least one component (e.g., Fe) of the material of the second wire decreases toward the distal end. When a tensile test is conducted on a region of the wire body including the joint, the region of the wire body has, in a tensile load and elongation diagram, an elastic section extending substantially straight upwardly to the right, a yield section extending substantially horizontally or upwardly to the right from the elastic section, and a substantially straight section extending upwardly to the right from the yield section.
    • 引导线包括具有设置在远端的第一线的线主体和通过焊接在接头处连接到第一线的近端的第二线。 关节弯曲。 在接头中,第一线材料的至少一个部件(例如Ti)朝向近端减小,并且第二线材料的至少一个部件(例如,Fe)朝向远端减小。 当在包括接头的线体的区域上进行拉伸试验时,线体的区域在拉伸载荷和延伸率图中具有基本向上向右延伸的弹性部分,基本上水平地延伸的屈服部分 或从弹性部分向上或向右的右侧,以及从屈服部分向右向上延伸的基本上直的部分。

    • A guide wire includes a wire body having a first wire disposed at a distal end thereof and a second wire joined to a proximal end of the first wire. The first wire and the second wire are preferably joined to each other by welding, providing a layer joint therebetween. The joint is of a curved shape, particularly a convex curved shape that is convex toward the proximal end of the wire body. In the joint, at least one component (e.g., Ti) of the material of the first wire decreases toward the proximal end and at least one component (e.g., Fe) of the material of the second wire decreases toward the distal end. When a tensile test is conducted on a region of the wire body including the joint, the region of the wire body has, in a tensile load and elongation diagram, an elastic section extending substantially straight upwardly to the right, a yield section extending substantially horizontally or upwardly to the right from the elastic section, and a substantially straight section extending upwardly to the right from the yield section. This region of the wire body possesses characteristics such that the region is fracturable near a terminal end of the straight section at a fracture position on other than the joint.
    • 引导线包括具有设置在其远端处的第一线的线体和连接到第一线的近端的第二线。 第一线和第二线优选通过焊接彼此连接,在它们之间提供层接合。 接头是弯曲形状,特别是凸起的弯曲形状,其朝向线体的近端凸出。 在接头中,第一线材料的至少一个部件(例如Ti)朝向近端减小,并且第二线材料的至少一个部件(例如,Fe)朝向远端减小。 当在包括接头的线体的区域上进行拉伸试验时,线体的区域在拉伸载荷和延伸率图中具有基本向上向右延伸的弹性部分,基本上水平地延伸的屈服部分 或从弹性部分向上或向右的右侧,以及从屈服部分向右向上延伸的基本上直的部分。 线体的该区域具有这样的特性,使得该区域在除了接头之外的断裂位置处在直线部分的终端附近是可断裂的。
