Abstract
A balloon catheter in which its inflatable and collapsible balloon is of larger diameter than adjacent portions of the catheter body. The balloon defines transition zones at the respective ends which are of fluted shape. Thus, the balloon can assume a collapsed position in which the collapsed transition zones collapse in a substantially star-shaped cross section rather than in a flat-collapsed configuration. Central portions of the catheter follow suit on collapse of the balloon, to avoid the undesired 'winging' phenomenon in balloon catheters, particularly PTCA catheters.
