<p>PURPOSE: To manufacture an intravascular porous catheter device which can be transplanted by a tunnel method. CONSTITUTION: For this intravascular catheter, its far end part only is formed into a porous pipe 1, and the catheter can be transplanted by a tunnel method. For this catheter, separate tubes 2a, 2b which are equal to the number of the holes on a first pipe, and form an intermediate part 2 by extending backward from the first pipe, and a near end part of an assembly part, are formed. This intravascular catheter is equipped with a single hole pipe 3 having a hard needle 4 which is suitable to perform a tunnel method at the terminal end part, and two connectors 5, 6 comprising an olive-shaped main body with a narrowed tip, wherein respective holes (1a), (1b) of the porous pipe are bonded to one of individual tubes 2a, 2b of the intermediate part 2, which are used to connect the end parts on the opposite side of the tubes 2a, 2b with a corresponding end part of the single hole pipe 3, are made of a plastic respectively, and are formed on the end part of a part to be bonded.</p> |
