Abstract
A balloon catheter including an elongated shaft and a balloon on a digital shaft section having a working section, and tapered sections having an inflated configuration with a non-circular transverse cross section. In one embodiment, the non-circular tapers are triangular, although alternative non-circular cross-sectional designs may be used, such as lobed tapers. The non-circular tapers deflate to form two or more deflated wings along at least a section of the deflated balloon. The deflated wings provide a deflated balloon with a relatively low profile, which facilitates repositioning or removal of the balloon catheter within the patient's vasculature.
