摘要:
A method of making a catheter tube includes extruding a first resin having a first predetermined rigidity through a first extruder; extruding a second resin having a second predetermined rigidity through a second extruder; controlling a mixing ratio of the first and second resins extruded from the first and second extruders; and molding the first and second extruded resins to form an integrally molded tube having at least a first region, a second region which possesses a rigidity greater than the first region, and a transition region between the first region and the second region and which possesses a rigidity varying from the same rigidity as the rigidity of the first region to the same rigidity as the rigidity of the second region.
