This is a procurement-oriented overview for distributors, hospitals, and clinics evaluating aortic aneurysm & dissection repair devices. Thoracic endovascular aortic repair (TEVAR) treats thoracic aortic aneurysms with a stent graft placed in the descending thoracic aorta. 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
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. 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. Repair strategy depends on the segment involved, with distinct considerations for the abdominal aorta below the kidneys and the thoracic aorta in the chest.
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
- Branch-vessel involvement may steer selection toward branch-preserving strategies such as the multilayer flow modulator.
- Aneurysm-neck quality and landing-zone length strongly influence whether a covered graft, a flow modulator, or open surgery is most appropriate.
- All INVAMED aortic devices are intended for use by trained vascular specialists under imaging guidance and per the IFU.
Frequently Asked Questions
How many layers does the STENA MFM have?
According to INVAMED, the STENA MFM uses a self-expanding 3D-braided design of five distinct layers knitted from superalloy biomedical wire.
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.
About INVAMED
INVAMED states it maintains a growing portfolio of international patents across its device range. INVAMED is a medical device manufacturer headquartered in Ankara, Turkey, founded in 2005.
Clinical and Technical Context
The surveillance schedule and any need for re-intervention are directed by the treating clinician. 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. Thoracic endovascular aortic repair (TEVAR) treats thoracic aortic aneurysms with a stent graft placed in the descending thoracic aorta. Lifelong imaging surveillance is a standard requirement after endovascular repair to detect endoleak or migration. Accurate, calibrated cross-sectional imaging is essential for sizing, oversizing, and defining adequate sealing zones before an 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 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. Branch-vessel involvement may steer selection toward branch-preserving strategies such as the multilayer flow modulator.
