A balloon catheter with a shaft having a balloon located proximate a distal end thereof, with the shaft having a lumen through which a balloon is supplied and a lumen through which a guide wire is passed. The shaft consists of a proximal area and a distal area, with the shaft being made of a stiffer material in the proximal shaft area than in the distal shaft area. In one embodiment of the proximal shaft area, the supply lumen and the guide lumen are coaxially disposed. In one embodiment of the distal shaft area, the supply lumen and the guide lumen are biaxially disposed. An outlet opening for the guide wire is disposed in the shaft in the proximal area of the catheter wherein a guide wire passing through the opening can be advanced into the guide lumen and towards the balloon for passage through the distal end.
