ABSTRACT:
A catheter assembly including a dilating catheter, a guiding catheter, and a length of tubing. The tubing is connected to the guiding catheter, and is pivotable between two positions. In the first position, the proximate end of the tubing is end to end with the tip of the catheter. In the second position, the proximate end of the tubing is adjacent the tip of the guiding catheter. The tubing has a plurality of side holes. A guide wire holds the tubing in the first position. The catheter assembly is inserted into the patient's aorta, while the tubing is in the first position. The guide wire is removed, and the tubing is pivoted to the second position. The proximate end of the tubing and the tip of the guiding catheter are then inserted into an artery. Angiography or angioplasty then proceeds normally.
