摘要： A catheter enabling an increase in operability when the catheter is inserted from the outside to the inside of a body and capable of remarkably reducing the risk of damage to shafts even in an unforeseen accident without complicating steps and increasing production cost. The catheter comprises at least the distal side shaft formed of a resin tube, the rear end side shaft with a higher rigidity than that of the distal side shaft, and a guide wire lumen. The catheter is characterized in that a core wire is disposed therein to adjust a flexibility so that the rear end portion of the distal side shaft is harder than the distal end portion of the distal side shaft and softer than the rear end side shaft, and the core wire is fixed to the distal side shaft near the rear end side opening part of the guide wire lumen and at a part of the rear end side portion of the distal end shaft.

摘要翻译： 导管能够在将导管从外部插入到身体内部时能够增加操作性，并且即使在意外事故中也能够显着降低轴的损坏风险，而不会使步骤复杂化并增加生产成本。 所述导管至少包括由树脂管形成的远端侧轴，所述后端侧轴具有比所述远侧侧的轴高的刚性，以及导丝管腔。 导管的特征在于，芯线设置在其中以调节柔性，使得远端侧轴的后端部比前端侧轴的前端部硬，并且比后端侧轴更软， 芯线固定在导丝管腔的后端侧开口部附近的远端侧轴线和远端轴的后端侧部的一部分。
