How is Angioplasty Performed?

During angioplasty, a thin, flexible tube called a catheter with a deflated balloon at its tip is inserted into the narrowed artery. Once in place, the balloon is inflated, pushing the plaque against the artery walls and widening the vessel. This improves blood flow. In some cases, a stent (a small mesh tube) is placed in the artery to help keep it open after the balloon is deflated and removed.
