Balloon catheter

Abstract

A balloon catheter having a distal-end tip which, even if caught in a stenosis, will not break apart from a distal end of an inner shaft of the balloon catheter when the balloon catheter is forcibly rotated or pulled by an operator. The distal-end tip of the balloon catheter is fixed to the distal end of the inner shaft, and a connecting tube covers an outer surface of the distal end of the inner shaft and a proximal end of the distal-end tip. An inwardly protruding portion of the connecting tube is embedded into the distal-end tip. This creates an anchoring effect and increases a welding area between an outer surface of the distal-end tip and an inner surface of the connecting tube, thereby reducing a risk that the distal-end tip will break apart from the distal end of the inner shaft.
