Angioplasty, also called balloon angioplasty, is a minimally invasive procedure performed by an interventional radiologist to improve blood flow in the body's arteries. In the angioplasty procedure, the physician threads a balloon-tipped catheter a thin tube called a catheter to the site of a narrow or blocked artery and then inflates the balloon to open the vessel. The balloon is then deflated and removed from the artery.
