A new endovascular abdominal aortic aneurysm (AAA) device seals the entire abdominal aortic aneurysm sac, improving long-term patient outcomes.
The Nellix EndoVascular Aneurysm Sealing (EVAS) system is designed for the treatment of infrarenal AAA by completely filling and sealing the aortic aneurysm sac in order to prevent device migration and potential endoleak, thus reducing the need for secondary interventions after endovascular AAA repair. The system includes balloon-expandable expanded polytetrafluoroethylene (ePTFE)-covered chrome-cobalt conformable alloy stents with oversized flow lumen to seal the entire aneurysm, and durable, biostable polyurethane endobags.
The system is deployed in four key steps. First, the Nellix catheters are introduced to visualize anatomy; stent flow lumens are then established; the endobags are prefilled with saline and angiographic seal is confirmed; and finally, the endobags are filled with a polymer polyethylene glycol (PEG)-based bio-compatible and bio-stable two-part solution mixture that cures and seals the entire aneurysm in less than 10 minutes. The Nellix EndoVascular EVAS is a product of Endologix (Irvine, CA, USA), and has received the European Community CE mark of approval.
“The new Nellix system was developed based upon physician feedback over the past two years. It incorporates several enhancements that simplify the procedure and expand the available sizes to treat a wider range of AAA patients and anatomies,” said John McDermott, CEO of Endologix. “We’d like to thank our physician collaborators for their many contributions during the development process and look forward to continued EVAS innovations in the future.”
“In our hospital, patients with short or aneurysmal iliac arteries represent 30% of the diagnosed AAAs. With the new Nellix system, we now have a solution for these challenging anatomies and look forward to treating more patients,” said associate Professor of surgery Andrew Holden, MD, of Auckland City Hospital (ACH; New Zealand). “The first procedures with the new Nellix system have been a success and post-procedure imaging confirmed the device was accurately deployed and the aneurysm was properly sealed.”
