ABSTRACT:
A catheter assembly and a method of performing percutaneous transluminal coronary angioplasty. The catheter assembly has a dilating catheter and a guiding catheter. The guiding catheter has an inflatable balloon near the tip for engaging the inner surface of the coronary lumen when inflated. The guiding catheter also has a side hole for perfusion of blood through the guiding catheter while the balloon on the guiding catheter is inflated. The balloon on the guiding catheter can be repeatedly inflated and deflated, and radiopaque material may be used to inflate the balloon on the guiding catheter. The method of performing percutaneous transluminal coronary angioplasty includes inserting the tip of the guiding catheter into a coronary lumen of a coronary artery, and inflating the balloon on the tip of the guiding catheter until the balloon engages the inner surface of the coronary lumen. A dilating catheter is then passed within the guiding catheter through a stenotic lesion within the coronary lumen. The balloon on the tip of the guiding catheter is deflated, and a balloon on the dilating catheter is inflated to dilate the stenotic lesion. The balloon on the dilating catheter is then deflated and the catheter assembly is removed from the coronary lumen.
