The U.S. FDA has granted 510(k) clearance to Livanova plc's Lifesparc system, a compact, advanced circulatory support (ACS) pump and controller with ready-to-deploy kits to support a variety of cannulation strategies. The new system replaces the old pump and controller for the company's Tandem system with a streamlined user interface and 40% greater power output and smaller, lighter controller that is half the size of the previous version.
