International Study Evaluates Cook Medical's Zenith Alpha TEVAR Device
August 11, 2015—Karl A. Illig, MD, et al published 1-year outcomes from a study evaluating the safety and effectiveness of the Zenith Alpha thoracic endovascular graft (Cook Medical) for the treatment of descending thoracic aortic aneurysms and large ulcers. The investigators concluded that early outcomes after Zenith Alpha implantation appear promising and suggest expanded thoracic endovascular aortic repair applicability in patients with smaller access vessels. They advised that longer-term follow-up is ongoing. The study is available online ahead of print in the Journal of Vascular Surgery.
According to the investigators, the Zenith Alpha device, with a 16- to 20-F delivery system, was developed to address vascular access issues associated with larger-profile devices and to increase conformability in tortuous anatomy.
