1. A method for making a balloon catheter, comprising:
providing a tubular body including a proximal end, a distal end sized for introduction into a patient's body, and a longitudinal axis extending therebetween;
forming a balloon from non-compliant material comprising first and second end regions and a central region therebetween;
attaching the end regions to the tubular member distal end at first and second spaced-apart attachment locations;
at least one of folding and rolling the balloon into a contracted condition around the tubular member distal end;
positioning a plurality of inelastic fibers around the balloon with the balloon in the contracted condition such that the plurality of inelastic fibers extend helically around an outer surface of the balloon; and
attaching first and second ends of the plurality of inelastic fibers adjacent the balloon end regions such that the plurality of inelastic fibers remain movable freely relative to the outer surface along at least the central region of the balloon.
