The company will launch Ultimaster DES in Europe, Latin America, and Asia (excluding Japan) in June 2014.
Ultimaster employs bioresorbable polymer applied only to the vessel contacting surface to ensure targeted drug delivery. Moreover the polymer and the drug are released simultaneously and within 3-4 months to eliminate long-term polymer exposure, a possible cause of late adverse events. These features are expected to reduce stent thrombosis*2 and to produce favorable long term clinical outcomes.
The Ultimaster DES is based on bio-ergonomic*3 stent design with a cobalt chromium alloy. Favorably low width/thickness of the stent struts enhances stent conformability to the vessel wall and faster healing process that could lead to better strut coverage. The platform is designed to enable the physicians to navigate the stent in tortuous anatomy and facilitate placement of the stent conformable to vessel curvature, further reducing stress on vessel wall for the aim of long-term patency.
“Ultimaster is a masterpiece of drug eluting stent with bioresorbable polymer, underpinned by our accumulated experience and expertise as a leading company in the technology,” said Hikaru Samejima, President of Terumo Interventional Systems. “Terumo will continue its commitment to innovation for true benefits for patients and physicians to provide genuine value to health care society.”
Design hypothesis is further supported by robust clinical evidence from the comprehensive clinical program. The results of CENTURY study confirmed high efficacy of Ultimaster DES with late loss at 6 months of 0.04mm. Despite the low late loss, the OCT assessed Ultimaster stent strut coverage at 6 months was 96.2±5.4%. At 12 months, the rate of target lesion revascularisation*4 was 2.8%, the rate of target lesion failure*5 2.9%, MACE*6 3.8%, with only one acute stent thrombosis. CENTURY II study is global, multicenter, randomized trial that enrolled 1123 patients in 58 hospitals in 13 countries. The primary endpoint results will be reported at the upcoming PCR 2014. There are additional studies on-going with Ultimaster Stent, including studies that potentially would pave the way for reduced dual antiplatelet therapy.

A stent is an implant device used in the treatment of angina pectoris, myocardial infarction, and other coronary events caused by blood vessels around the heart (coronary artery) that are stenosed or blocked. After expanding coronary artery with a balloon catheter*7, the stent is implanted in a vessel. However, since stenosis may occur after implanting, drug-eluting stent are often used.Drug-eluting stent is expected to reduce tissue proliferation that may cause restenosis (narrowing of the treated part of the vessel) because its drug is gradually released to surrounding tissues.
