ABSTRACT:
In a catheter comprising a proximal inner tube having a reinforcing layer applied thereto and a distal inner tube made of a material having different physical properties from those of the proximal inner tube, the proximal and distal inner tubes are axially integrally connected such that the outer surface of the proximal inner tube is substantially smooth and continuous to that of the distal inner tube, and a sheath continuously covers the proximal and distal inner tubes. The catheter is produced by axially integrally joining proximal and distal inner tubes and continuously covering the interconnected tubes with a sheath.
