Abstract
A balloon catheter and method for manufacturing are disclosed in which the fracturing of the vicinity of a proximal opening portion formed by an inner shaft can be prevented. A distal side of an inner shaft included by a balloon catheter is disposed in a lumen of an outer distal shaft, and a proximal side of the inner shaft is disposed on an outer surface of an outer proximal shaft, and the inner shaft forms a proximal opening portion which opens on an outer surface side of the outer proximal shaft. The inner shaft has a first region and a second region disposed on a proximal side of the first region. The first region is fixed to the outer surface of the outer proximal shaft. The second region is not fixed to the outer surface of the outer proximal shaft.
