Abstract
A method of forming a catheter component, such as a balloon, in which the component has a thinned skirt section formed by expanding tubing to a radially enlarged outer diameter and then decreasing the inner diameter and the outer diameter of the radially enlarged skirt section before or during bonding of the skirt section to the catheter shaft. The method generally includes blow molding tubing in a balloon mold having a skirt portion with an inner diameter which is larger than an outer diameter of the thinned skirt section of the balloon, so that the balloon mold produces a balloon having a radially enlarged skirt section with a larger outer diameter than is desired for the finished balloon. By then decreasing the diameter of the radially enlarged skirt section, the resulting skirt section is thinned, to provide a balloon catheter having improved flexibility and low profile.
