Cook's abdominal aortic aneurysm (AAA) stent graft, Zenith, is a strong competitor in the endovascular sector and was recently launched in Japan (it's also is the first and only such device there). And out of the 6200 AAA stent grafts implanted in the United States in the third quarter, the Zenith endograft came in second with 37% of the market, behind Gore's graft by a mere 1%. However, during the same quarter in Europe, Zenith was at the top with 47% of the market and a 15% lead. Cook's endovascular unit has also expanded in Japan, Taiwan, and South America, and is positioned in what Thomas labeled the "emerging" markets of China, India, and Korea. The division is also keeping endovascular disorders such as disease in the ascending aorta and thoraco-abdominal disease on its radar screen for future device development.
