Abstract
A balloon catheter is configured so as to comprise a catheter shaft formed by joining a proximal-side tubular member and a distal-side tubular member , an adapter member connected to the base end of the catheter shaft , and a balloon joined to the distal end of the catheter shaft . A metal coiled elastic member is deployed in the internal space in the adapter member , so that it can move toward the distal end. This coiled elastic body abuts on a ring-shaped wall part formed on the outer circumferential surface of the base end of an elastic force transmitting member and supports the elastic force transmitting member to the distal side. The leading end of a linear member that is one of the components of the elastic force transmitting member reaches to an internal space in the balloon and is bonded to the outer circumferential surface of a guide wire passing tube . Thus the elastic supporting force of the coiled elastic body is transmitted via the elastic force transmitting member to the distal-side sleeve part of the balloon , and tension is imparted to the balloon in the axial direction.
