A dilation catheter of the invention is formed of a flexible tube having distal and proximal ends, and a balloon attached to the distal end of the tube. The catheter includes a first opening formed in the tube to communicate with the balloon, and a second opening formed in the tube near the proximal end of the balloon. A partition is located inside the tube to communicate the proximal end of the tube with the first opening. Thus, inflation and deflation of the balloon attached to the tube can be controlled by fluid applied through the tube. A guide wire extends through the tube between the distal end and the second opening.
