balloon angioplasty
[bəlo̅o̅n′]
a method of dilating or opening an obstructed blood vessel by threading a small, balloon-tipped catheter into the vessel. The balloon is inflated to compress arteriosclerotic lesions against the walls of the vessel, leaving a larger lumen, through which blood can pass. It is used in treating arteriosclerotic heart disease.

Cardiology A minimally invasive procedure in which a catheter with an inflatable balloon tip is inserted through the femoral or brachiocephalic artery and 'snaked' to a previously identified–by
angiography zone of arterial stenosis or occlusion. See Atherosclerosis, Cholesterol, Percutaneous transluminal coronary angioplasty. Cf Stenting.
