Abstract

See full text

Provided is a balloon catheter wherein a balloon is less likely to swell in the protective tube during an air leak test of the balloon in a state where the balloon having projecting portions is housed in a lumen of the protective tube. A balloon catheter contains: a shaft extending in a distal-proximal direction; a balloon having wing-shaped portions; projecting portions disposed on an outer surface of the balloon; and a protective tube in which the balloon is disposed, wherein, in a cross section perpendicular to the distal-proximal direction at a midpoint of a length in the distal-proximal direction of the protective tube, a distance from a centroid of the protective tube through an apex of each projecting portion to an inner surface of the protective tube is longer than a distance from the centroid through none of the projecting portions to the inner surface of the protective tube.
