Abstract

A balloon catheter includes a balloon/shaft assembly and a linear member. The balloon/shaft assembly includes a catheter shaft extending from a proximal end to a distal end and a balloon connected to the catheter shaft. The linear member straddles an inflatable region of the balloon and is mounted on the balloon/shaft assembly. The linear member includes a hard portion and a flexible portion. The hard portion includes at least an outer portion disposed on an opposite side to an inner portion facing the inflatable region, of a portion disposed along an outer peripheral surface of the inflatable region in an inflated state. The flexible portion is a portion other than the hard portion. The flexible portion is extendable and has a lower hardness than the hard portion.
