April 6, 2017 — Endologix Inc. announced that the first patients were treated in the Expanding Patient Applicability with Polymer Sealing Ovation Alto Stent Graft (ELEVATE) IDE clinical study.
ELEVATE IDE is the company’s pivotal clinical trial to evaluate the safety and effectiveness of the Ovation Alto Abdominal Stent Graft System for the repair of infrarenal abdominal aortic aneurysms (AAAs). The trial is approved to enroll 75 patients at up to 12 centers in the United States. The first procedure was performed by Steve Henao, M.D., chief, Division of Vascular Surgery at New Mexico Heart Institute.
The study principal investigator, Sean Lyden, M.D., chairman of the Department of Vascular Surgery at Cleveland Clinic commented, “We are excited to start treating patients in the ELEVATE IDE trial. The polymer technology in the device allows for active sealing in the aortic neck. The polymer sealing ring has proven durability in maintaining aneurysm exclusion to five years as reported in the Global Ovation Pivotal Trial. The repositioning of the sealing ring to 7mm below the top of the fabric will allow treatment of more challenging and complex anatomies in this trial.”
Ovation Alto is the newest device in the Ovation platform of abdominal stent graft systems, which has proven clinical results reported from the Ovation global pivotal trial and European Post-Market Registry. Ovation Alto expands endovascular aortic repair (EVAR) to treat more patients on IFU. This is achieved by the conformable O-rings with CustomSeal polymer that have been repositioned near the top of the endograft, providing seal just below the renal arteries.
The Ovation platform is the lowest profile U.S. Food and Drug Administration (FDA)-approved EVAR device, and it has been used successfully in the treatment of over 12,000 patients worldwide. Ovation Alto is an investigational device and currently not approved in any market.
Endologix CEO John McDermott said the company expects Ovation Alto could be available in the U.S. in 2019, based on the anticipated enrollment timeline.
