Abstract
A balloon dilatation catheter is provided with a pleated balloon defining at least three pleats and alternating wings. When the balloon collapses, it tends to assume a pleated configuration which defines a lower profile and is better adapted to pass through narrow channels, such as a guide catheter. The balloon is formed from a polymeric material in a method that involves the steps of extruding a tube having at least three circumferentially spaced, longitudinally extending segments of less wall thickness than the remainder of the tube, and biaxially stretching the tube to a predefined shape while maintaining the longitudinal segments of reduced wall thickness.
