This is a procurement-oriented overview for distributors, hospitals, and clinics evaluating aortic aneurysm & dissection repair devices. An aortic aneurysm is an abnormal, progressive dilation of the aorta that carries a risk of rupture as it enlarges, while an aortic dissection is a tear within the wall that separates its layers. As a medical device manufacturer, INVAMED develops technologies in this area; the information here is educational and not medical advice.
Background: Aortic Aneurysm and Dissection Endovascular Repair
Repair strategy depends on the segment involved, with distinct considerations for the abdominal aorta below the kidneys and the thoracic aorta in the chest. Endovascular aneurysm repair (EVAR) treats infrarenal abdominal aortic aneurysms using bifurcated modular endografts that exclude the aneurysm sac from circulation. An aortic aneurysm is an abnormal, progressive dilation of the aorta that carries a risk of rupture as it enlarges, while an aortic dissection is a tear within the wall that separates its layers.
Regulatory Status and Manufacturing
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
Portfolio and Sizing
Within this category, INVAMED lists devices such as STENA Aortic Multi-Layer Flow Modulator, Atlas Aortic Stent Graft, Atlas Endovascular Stent Graft, Atlas Aortic Nitinol Stent. Size ranges, materials, and configurations are detailed in product documentation and the applicable IFU.
Key Considerations
- Manufacturer descriptions of flow modulation and radial support reflect design intent rather than guaranteed clinical outcomes.
- Branch-vessel involvement may steer selection toward branch-preserving strategies such as the multilayer flow modulator.
- Lifelong imaging surveillance is a standard requirement after endovascular repair to detect endoleak or migration.
Frequently Asked Questions
What is the difference between EVAR and TEVAR?
EVAR treats infrarenal abdominal aortic aneurysms with bifurcated modular endografts, while TEVAR treats thoracic aortic aneurysms with a stent graft in the descending thoracic aorta.
What is the INVAMED flow modulator called?
INVAMED's flow-modulating aortic device is the STENA Aortic Multi-Layer Flow Modulator, a self-expanding multilayer braided scaffold intended to preserve branch vessels.
Who decides if an aneurysm needs repair?
A vascular specialist decides using current size thresholds and imaging; this article is educational and not a treatment recommendation.
Clinical and Technical Context
Durable exclusion depends on adequate proximal and distal sealing zones, which are assessed on pre-procedure imaging by the clinician. INVAMED's Atlas Endovascular Stent Graft and Atlas Aortic Stent Graft are positioned for this sac-exclusion role in the abdominal aorta. The decision to pursue a branch-preserving device rather than a covered graft rests with the treating clinician. Manufacturer descriptions of flow modulation and radial support reflect design intent rather than guaranteed clinical outcomes. Thoracic endovascular aortic repair (TEVAR) treats thoracic aortic aneurysms with a stent graft placed in the descending thoracic aorta. Follow-up imaging is used to confirm that the sac remains excluded and stable over time. INVAMED's Atlas aortic stent-graft line addresses thoracic applications within the endovascular portfolio. Endovascular repair reaches the aorta through the femoral arteries and deploys a device from inside the vessel, avoiding a large open incision in appropriately selected patients.
