Abstract
A method of making a catheter balloon, and a balloon catheter formed thereby, in which a layer of a catheter balloon is formed by decreasing the inner diameter of a first end section of a polymeric tube, so that the tube has a reduced diameter first end section with an inner diameter less than the inner diameter of a central section of the tube. The reduced diameter first end section of the tube is bonded to a catheter shaft to form at least a portion of a skirt section of the balloon, and the skirt section has an improved high rupture pressure.
