Angioplasty and stenting are minimally invasive procedures performed to open clogged arteries and improve blood flow. Angioplasty involves inserting a balloon-tipped catheter in the blocked area and expanding it to stretch the artery walls, allowing blood to flow. A stent, or small wire-mesh tube, may be permanently placed in the newly opened artery to help it remain open. Drug-eluting stents may be used to further reduce restenosis. Stenting is available at CHI Memorial.
