Abstract
A balloon dilatation catheter comprising an elongated tubular shaft and an inner tube defining inflation and guide wire lumens. A dilatation balloon is mounted on the distal end of the tubular shaft and communicates with the inflation lumen. The guide wire lumen extends through the balloon. A stiffening wire is positioned within the tubular shaft and has a proximal end secured in the proximal portion of the catheter. The distal end of the stiffening wire is anchored within the inner tube in an area adjacent the guide wire entrance port. The stiffening wire maximizes strength to the proximal portion of the catheter while maintaining flexibility in the distal end of the catheter as well as the balloon.
