OBJECTIVE: This study evaluated the 2-year safety and effectiveness of the European First-in-Human INNOVATION trial for the INCRAFT AAA Stent Graft system (Cordis Corp, Bridgewater, NJ), an ultra-low-profile device for the treatment of abdominal aortic aneurysms. METHODS: From March 2010 to June 2011, the INNOVATION prospective multicenter trial involving six centers in Europe enrolled and treated 60 asymptomatic patients (95% male; mean age, 74.4 ± 6.9 years) with the INCRAFT System. Main inclusion criteria included proximal aortic neck length of 15 mm or more with a diameter up to 27 mm; distal iliac landing zones with a length greater than 10 mm and a diameter between 9 and 18 mm; and aortic bifurcation >18 mm in diameter and access vessels large enough to accept the 14F outer diameter of the delivery system. The primary end point was technical success at 1 month; 2-year safety end points included the absence of device- or procedure-related major adverse events, absence of type I or III endoleaks, and maintenance of device integrity through 2 years of follow-up. Study oversight was provided by a Data Safety Monitoring Board with event adjudication by a Clinical Events Committee and imaging analysis by an independent core laboratory. RESULTS: Of 60 successfully treated patients, two did not come back for their 1-month evaluation but remained enrolled in the study; 56 were evaluated at 1 year and 52 at 2 years. Of the 58 patients, 56 met the 1-month primary safety and effectiveness end point (97%; 95% confidence interval, 88%-100%). All patients were free from aneurysm enlargement through 2 years. There were no type I or III endoleaks at the 2-year time point. All-cause mortality at 2 years was 11.5%, and no death was device or procedure related. In total, three patients required a postprocedure intervention, two to repair a type I endoleak and one for limb occlusion. Core laboratory evaluation of the postoperative imaging studies documented absence of endograft migration and stent fractures in all patients. CONCLUSIONS: The INCRAFT AAA Stent Graft System provides a durable solution for patients with abdominal aortic aneurysms, with a low frequency of device-related events through 2 years of follow-up.

METHODS: From March 2010 to June 2011, the INNOVATION prospective multicenter trial involving six centers in Europe enrolled and treated 60 asymptomatic patients (95% male; mean age, 74.4 ± 6.9 years) with the INCRAFT System. Main inclusion criteria included proximal aortic neck length of 15 mm or more with a diameter up to 27 mm; distal iliac landing zones with a length greater than 10 mm and a diameter between 9 and 18 mm; and aortic bifurcation >18 mm in diameter and access vessels large enough to accept the 14F outer diameter of the delivery system.
