In 2001 the company made two more acquisitions: it acquired the home oxygen division of Sumitomo Bakelite Co., Ltd., and establish Terumo Medical Care K.K., and Ikiken Co., Ltd. of Japan. In 2002 the company enters into the vascular prostheses business by acquiring UK-based Vascutek Ltd. Four years later, in 2006 the company ventured into a new field (endovascular coils for the treatment of cerebral aneurysms) by buying American company MicroVention Inc. The tissue heart valve division of Kohler Chemine GmbH was acquired in March 2007 and expanded Terumo's operations related to vascular prostheses. A year later the Japanese company Clinical Supply Co., Ltd. became a Terumo subsidiary and enhanced Terumo's interventional systems business in the field of radiotherapy. In March 2011, the company bought U.S. medical device company CaridianBCT for around $2.6 billion. It was the largest acquisition by a Japanese medical equipment maker at the time. The same year Harvest Technologies Corporation—point-of-care cell therapy—and Onset Medical Corp.—sheath technology designed for multiple, minimally-invasive clinical applications—was acquired. In 2018, after the acquisition of Bolton Medical, a merger with Vascutek Ltd. gave place to the new company Terumo Aortic, focusing on “expanding aortic treatment options.”
