A catheter includes a proximal shaft 15 having a relatively high rigidity, a distal shaft 13 provided on a front portion of the proximal shaft so as to be in fluid communication with proximal shaft 15 and having a rigidity lower than that of the proximal shaft 15, a hub 16 mounted to the vicinity of a rear end of the proximal shaft 15 and configured to allow a pressure applying apparatus to be mounted to the hub 16, and a balloon 12 provided on a front portion of the distal shaft 13 so as to be in fluid communication with the distal shaft 13 and configured to receive pressure applied from the hub 16. The catheter also includes a guide wire lumen for allowing a guide wire to be inserted through the guide wire lumen. The guide wire lumen has a distal side aperture positioned on the front side from a front end of the balloon 12 and a proximal side aperture positioned on the rear side from a rear end of the balloon 12. In this catheter, at least a front portion of the distal shaft 13 is configured as a grooved portion 131 having a groove or grooves 132. <IMAGE> |
