PTA (Percutaneous Transluminal Angioplasty) Balloon Catheter is a minimally invasive medical device used to treat narrowed or blocked blood vessels. It is primarily employed in angioplasty procedures to restore blood flow by dilating the vessel lumen. The catheter features an inflatable balloon at its tip, which expands to compress plaque or lesions against the vessel wall, thereby improving blood flow.

PTCA Balloon Catheter is mainly used to treat coronary heart disease (such as angina pectoris, myocardial infarction, etc.), by dilating narrowed or occluded coronary arteries with a balloon, improving myocardial blood supply. It is an important tool in interventional cardiology and widely used in cardiac catheterization rooms.
