Abstract
The invention is directed to a guiding catheter for intraluminal procedures, such as stent delivery, balloon dilatation, atherectomy and the like, and for advancing and delivering intraluminal devices within body lumens. The guiding catheter in accordance with the invention has a multi-strand braided reinforcement layer within the wall of the catheter that has a distal end which is at an angle of at least 15° from a transverse plane perpendicular to the longitudinal axis of the catheter. This construction of the reinforced braided layer assists in the retraction of an intraluminal device back into the inner lumen of the guiding catheter. The guiding catheter may have an inner layer that has a distal end that is also at an angle with respect to a transverse plane perpendicular to the longitudinal axis.
