    • A guide wire, and a method for the manufacture thereof, having a core and a plastic jacket enclosing the core. The plastic jacket comprises a proximal portion formed of a first plastic material and a distal jacket portion formed of a second plastic material. The distal end of the proximal jacket portion and the proximal end of the distal jacket portion substantially abut each other and are of substantially equal outer diameters so as to form a smooth transition between the proximal and the distal jacket portions. According to another aspect, there is provided a guide wire with a selectively formable metallic core and a plastic jacket encasing the formable core. The plastic jacket has a distal portion with a hydrophilic coating and a proximal portion without a hydrophilic coating. According to another aspect, there is provided a guide wire having a formable metallic core and a plastic jacket encasing the formable core. The plastic jacket has a distal portion that is more radiopaque than a proximal portion.
    • 一种导丝及其制造方法,其具有包围芯的芯和塑料外套。 塑料外套包括由第一塑料材料形成的近端部分和由第二塑料材料形成的远端护套部分。 近侧护套部分的远端和远侧护套部分的近端基本上彼此邻接并且具有基本相等的外径,以便在近侧护套部分和远侧护套部分之间形成平滑过渡。 根据另一方面,提供了一种具有可选择成形的金属芯和包封可成型芯的塑料套的导丝。 塑料护套具有远端部分,其具有亲水性涂层和不具有亲水涂层的近端部分。 根据另一方面,提供了一种导丝,其具有可成形金属芯和包封可成形芯的塑料外壳。 该塑料外套具有比近侧部分更不透射线的远侧部分。
