Abstract
A balloon dilatation catheter comprises a flexible, tubular catheter shaft which carries a dilatation balloon adjacent the distal end. The catheter shaft defines an inflation lumen communicating with the balloon and a guidewire lumen extending at least most of the length of the catheter and extending through the catheter distal end. A longitudinal slit is defined in the catheter shaft between the guidewire lumen and the catheter exterior. This slit longitudinally extends along the majority of the catheter length from a position proximal of the balloon to a position that is at least adjacent the catheter proximal end.
