The Atlas Aortic Stent Graft is an INVAMED covered stent system engineered for endovascular repair of thoracic and abdominal aortic pathology. This overview summarizes the device's intended use, design features, and construction, based on published specifications, to support physicians evaluating aortic repair device options.
What Is the Atlas Aortic Stent Graft?
Atlas Aortic Stent Graft is a covered stent system intended for endovascular repair of thoracic or abdominal aortic aneurysms (TAA/AAA), aortic dissections, or traumatic aortic injuries. The device is designed to be deployed within the aorta to redirect blood flow through a sealed conduit, working to prevent aneurysm sac pressurization while maintaining safe lumen patency.
What Are the Design and Material Specifications?
According to INVAMED's published specifications, Atlas Aortic Stent Graft features:
- Design: Available in balloon-expandable or self-expanding configurations, with a covered stent construction using ePTFE graft material
- Base scaffold material: Nitinol alloy
- Graft covering: ePTFE / PTFE
- Deployment mechanism: For self-expanding configurations, a sheath-based release system
- Sizing: A wide range of sizes, diameters, and tapered configurations designed to accommodate individual patient anatomy
The main body stent is designed for high conformability, attributed to varying stent height along its length, while maintaining kink resistance intended to support durable patency in tortuous or angulated anatomy.
What Design Features Support Dissection and Fixation Needs?
Atlas incorporates multiple tapered configurations intended to support the treatment of aortic dissections, where a graduated diameter profile may be needed to accommodate the true and false lumen anatomy. The proximal seal design incorporates a novel proximal stent configuration along with a mini spring feature intended to enhance wall apposition at the sealing zone.
For fixation, the device is engineered to provide two levels of confident fixation, and incorporates lock stent technology intended to help prevent modular disconnection between graft components in modular configurations. A unique leave-behind sheath is also part of the delivery system, intended to help simplify procedural workflow.
What Is the Intended Clinical Context for Atlas?
Atlas is positioned within INVAMED's Aortic Aneurysm & Dissection Repair category, intended for interventional procedures performed by trained healthcare professionals specializing in aortic and endovascular care. As an endovascular alternative to open surgical repair, stent graft-based approaches are generally associated with a less invasive access strategy and, in many cases, a shorter recovery period compared with open surgery, though outcomes and suitability vary by patient anatomy and clinical presentation. All procedures carry inherent risks, and device selection and candidacy are determined by the treating physician.
