Title: Catheter having optimized balloon taper angle

Abstract: A dilation catheter and expandable balloon. The catheter includes a catheter tube, a proximal end, a distal end and an axis which extends between the proximal and distal ends. A balloon has two ends, at least one end mounts on the distal end of the catheter. The balloon inflates and deflates between a collapsed configuration and an expanded configuration. The balloon has a tapered portion and a working length. The tapered portion extends from the catheter tube at an angle .alpha. within the range of 7.degree. to 20.degree. and attaches the working length of the balloon to the catheter tube. Accordingly, the angle .alpha. between the tapered portion and the catheter tube is optimized to enable the balloon to slide when the balloon is in the collapsed configuration.
