PROBLEM TO BE SOLVED: To provide a method and an apparatus for manufacturing an integral catheter having a tube and a hub. SOLUTION: The method for manufacturing the integral catheter comprises a step of supplying a molten material into a mold having a molding porous part. In this case, a fluid like a gas is supplied into a supply port of the mold. A molten central part of a gas polymer is extruded from an outlet passage by this process. In one embodiment, the gas is supplied to a hub hart of the porous part. In another embodiment, the gas is supplied to a catheter part of the mold. The method also comprises a step of forming a first part of an intravascular unit by a first material in a first mold. Thereafter, a first part in the intravascular unit is inserted into a second mold, and a second part is formed of a second material. Thereafter, the gas is introduced, and a hollow passage is formed in the second part. |
