Abstract
A balloon catheter includes a balloon and an inner shaft. The inner shaft includes a marker member arranged on an outer periphery of a coil body having a sparsely wound portion in which gaps are formed between adjacent windings of the wire of the coil body. A distal end part and a proximal end part of the marker member are arranged at a position facing a void formed within one of the gaps between the adjacent windings of the wire of the coil body. The inner shaft of the balloon catheter therefore will not buckle, preventing damage to the balloon by contact with the marker member when the balloon catheter is passed through the inside of a curved blood vessel.
