Abstract
To provide a balloon catheter and an apparatus and method for manufacturing the balloon catheter, whereby the degree of welding can be appropriately adjusted and the balloon catheter can be formed so as to have a desired surface profile suitable for various uses including medical use.With a shaft 14 inserted through a catheter tube 30a inserted into an end portion 28b of a balloon and also with a pressure tube 32a fitted around a welding section where the end portion 28b of the balloon 28 is lapped over the catheter tube 30a, the shaft 14 is heated by emitting laser light from a laser radiation unit 8 to the welding section while the shaft 14 is rotated by a chuck, to weld the welding section.
