A balloon catheter includes an outer shaft, an inner shaft, and an inflatable balloon. The inner shaft is inserted inside the outer shaft. A part of the inner shaft extends from a leading end of the outer shaft. The balloon includes a base end side joint portion joined to the outer shaft and a leading end side joint portion joined to the inner shaft. The inner shaft has an extension portion configured to in an axial line direction. The extension portion is provided further to a base end side than the leading end side joint portion.

Balloon catheter

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.

A balloon catheter includes an outer shaft, an inner shaft, and an inflatable balloon. The inner shaft is inserted inside the outer shaft. A part of the inner shaft extends beyond a leading end of the outer shaft. The inflatable balloon includes a base end side joint portion and a leading end side joint portion, the base end side joint portion is joined to the outer shaft and the leading end side joint portion is joined to the inner shaft. The inner shaft has an extension portion configured to extend in an axial line direction. The extension portion is located closer to the base end side of the outer shaft than to the leading end side joint portion of the inflatable balloon.
