ABSTRACT:
A catheter balloon for use in dilation procedures, such as angioplasty, has multiple pleats formed therein, preferably six such pleats, that may be folded, or wrapped, circumferentially around the catheter to provide a minimized outer diameter when the balloon is deflated. The balloon pleats form six wings in the balloon and each of the balloon wings has a length such that it overlaps a portion of an adjoining wing and each wing extends about one-quarter of the circumference of the catheter shaft. A device for forming such folds in a balloon includes a forming chamber and a plurality of forming elements radially disposed around the balloon.
