This undated image provided by Abbott shows their experimental heart stent “Absorb”. The FDA holds a meeting Tuesday, March 15, 2016, to review Abbott Laboratories’ first-of-a-kind heart stent that dissolves into the body after helping to clear fat-clogged arteries. Stents are tiny, mesh-wire tubes that prop open arteries after they have been cleared of fatty plaque. They have grown into one of the most widely-used medical implants ever, but sales have been tempered by rare, risky complications. (Photo by Weinberg-Clark Photography/Abbott via AP Photo)
