Title:
BALLOON CATHETER
Document Type and Number:
WIPO Patent Application WO/2022/264744
Kind Code:
A1
Abstract:
In a balloon catheter, a straight tube part 13c of a balloon 13 is provided with a linear protrusion 30 that protrudes from an outer surface 25 and extends in the axial direction of the straight tube part 13c. A protruding part 30 has a top part 33 extending in the longitudinal direction of the protruding part 30 at the end on the protruding side. The protruding part 30 has an inclined region 31 in which, as a region where the top part 33 is inclined with respect to the outer surface 25 of the straight tube part 13c, the top part 33 is inclined so as to approach the outer surface 25 towards the distal side. Due to the protruding part 30 having the inclined region 31, the protruding height from the outer surface 25 of the straight tube part 13c is lower on the distal side than on the proximal side in the region from the distal end of the protruding part 30 to the proximal end of the inclined region 31.
