August 2, 2016 —The U.S. Food and Drug Administration (FDA) granted market clearance for W. L. Gore & Associates’ Gore Tigris Vascular Stent, a dual-component stent with a unique fluoropolymer / nitinol design. The Gore Tigris device, which gained CE mark approval in 2011, is a third generation, self-expanding stent. The device was designed explicitly to improve anatomical conformability with the natural movement of the knee when treating peripheral artery disease (PAD).
