BALLOON TUBE, BALLOON, BALLOON CATHETER, AND BALLOON TUBE FABRICATION METHOD

摘要

In a balloon tube (10) which is processed after it is mounted on a mold, a bag part (14) has a plurality of parts having a different drawability in a radial direction centered around an axial direction X, disposed along the axial direction X. The highest drawability part (11), which has the highest drawability, is disposed to separate from both ends of the bag part (14) in the axial direction X thereof. The balloon tube (10) is preferable to stably fabricate a balloon having a uniform film thickness.
