Angioplasty: Angioplasty or percutaneous transluminal angioplasty (PTA) is a technique used to widen the narrowing in your artery without surgery. A catheter (thin tube) with a small inflatable balloon on the end is inserted into the narrowed section of the artery. The balloon is inflated so it pushes outward against the plaque and surrounding wall of the artery, reducing the narrowing to improve blood flow. The balloon is then deflated and removed from the artery.
Stent Implantation: Many patients who have an angioplasty also have a stent implanted. A stent is a small, mesh, metal tube that is placed in your blood vessel on a balloon catheter. The stent expands against the vessel wall as the balloon is inflated. Once the balloon has been deflated and withdrawn, the stent stays in place permanently, helping to keep the blood vessel open and improve blood flow.
Cryoplasty: This special type of angioplasty uses a balloon filled with nitrous oxide (rather than saline solution as in traditional angioplasty), which cools and turns into a gas to expand the balloon. The gas gently cools the inside of the vessel, which weakens the plaque as it opens up the blockage.
