Title:
BALLOON CATHETER
Document Type and Number:
WIPO Patent Application WO/2018/096572
Kind Code:
A1
Abstract:
[Problem] To provide a balloon catheter configured so that: when the balloon is contracted, a balloon can be quickly inserted up to a narrowed section or a closed section; when the balloon is expanded, an uneven surface region can be freely disposed on the balloon in order to reliably affix the balloon to the narrowed section or the closed section; such a balloon can be easily manufactured; and at the time of folding the balloon, the balloon can be freely folded without distinguishing between the uneven surface region and the remaining region. [Solution] This balloon catheter 1 comprises a balloon 3 having: a base section 3x having an uneven surface region P on the surface thereof; and a coating agent 3d coated on the surface of the base section 3x. Before the balloon 3 is expanded, the surface of the balloon 3 is smooth because of the coating agent 3d, and when the balloon 3 is expanded, the surface of the balloon 3 has an uneven shape because of the uneven surface region P of the base section 3x.
