Abstract

PURPOSE: To prepare a catheter equipped with a dilator having a uniform wall thickness, by forming an inner tube having an opened rumen and an outer tube having an inner diameter larger than that of the inner tube and shorter than said inner tube by a predetermined length while forming the dilator having a leading end part and a base end part and fixing the base end part of the dilator to the leading end part of the outer tube while fixing the leading end part thereof to the leading end part of the inner tube.
CONSTITUTION: An inner tube 1 having the first rumen 4 formed thereto so as to communicate with the leading and rear ends thereof is formed and an outer tube 2 having the second rumen formed thereto so as to communicate with the leading and rear ends thereof is formed. A tube 30 made of a thermoplastic resin forming a dilator 3 is formed and a holder 40 is mounted to said tube 30 at the part of an A-A line to close the rumen of the tube 30. The tube 30 is pulled in the direction shown by an arrow B to remove the slackening thereof and heated to the vicinity of the m.p. of the material quality thereof. A mold 42 is allowed to cover the tube 30 and air is sent into the tube 30 in the direction shown by an arrow C to closely bring the tube 30 into contact with the inner wall surface of the mold 42 and the tube 32 is allowed to stand in a pressurized state until returned to the ambient temp. and the mold 42 is pulled off while the leading end part 34 and rear end part 36 of the to be 30 are cut to form the dilator 3. The base end part of the dilator 3 is fixed to the leading end part of the outer tube 2 and the leading end part of the dilator 3 is fixed to the leading end part of the inner tube 1.
