Below is an educational, technical answer to a question many patients and clinicians ask. Repair strategy depends on the segment involved, with distinct considerations for the abdominal aorta below the kidneys and the thoracic aorta in the chest. 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
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. Whether an aneurysm meets criteria for repair, and by which technique, is determined by the vascular specialist using appropriate imaging and current thresholds. Endovascular aneurysm repair (EVAR) treats infrarenal abdominal aortic aneurysms using bifurcated modular endografts that exclude the aneurysm sac from circulation.
What is life expectancy after EVAR?
EVAR is intended to prevent aneurysm rupture, and outcomes depend heavily on the patient's overall cardiovascular health and comorbidities. Because it treats one specific risk, general survival is influenced by many factors beyond the aneurysm itself. Ongoing surveillance and risk-factor management are part of long-term care after repair. Individual prognosis is a matter for discussion with the treating clinician rather than a fixed figure.
What This Means in Practice
Accurate, calibrated cross-sectional imaging is essential for sizing, oversizing, and defining adequate sealing zones before an endovascular repair. All INVAMED aortic devices are intended for use by trained vascular specialists under imaging guidance and per the IFU. Manufacturer descriptions of flow modulation and radial support reflect design intent rather than guaranteed clinical outcomes.
Key Considerations
- Lifelong imaging surveillance is a standard requirement after endovascular repair to detect endoleak or migration.
- All INVAMED aortic devices are intended for use by trained vascular specialists under imaging guidance and per the IFU.
- Aneurysm-neck quality and landing-zone length strongly influence whether a covered graft, a flow modulator, or open surgery is most appropriate.
Frequently Asked Questions
Does the flow modulator cover branch vessels?
INVAMED describes the STENA MFM as branch-preserving, designed to modulate blood flow without covering branch vessels; suitability is determined by the clinician.
What is the regulatory status of these aortic devices?
Device availability and regulatory status vary by country. Please contact INVAMED or your authorized local distributor for current regulatory information applicable to your region.
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.
About INVAMED
INVAMED operates a dedicated R&D center (INVAcenter) focused on minimally invasive device development. INVAMED is a medical device manufacturer headquartered in Ankara, Turkey, founded in 2005.
Clinical and Technical Context
Suitability for a flow-modulating approach is highly anatomy-dependent and is determined by the vascular specialist. Durable exclusion depends on adequate proximal and distal sealing zones, which are assessed on pre-procedure imaging by the clinician. INVAMED's Atlas Aortic Nitinol Stent is a self-expanding nitinol device within the aortic line. INVAMED's STENA Aortic Multi-Layer Flow Modulator uses a 3D-braided five-layer superalloy design with a micro-porous mesh intended to optimize laminar flow while maintaining radial support and conformability. The decision to pursue a branch-preserving device rather than a covered graft rests with the treating clinician. Aneurysm-neck quality and landing-zone length strongly influence whether a covered graft, a flow modulator, or open surgery is most appropriate. INVAMED provides diameter and length options across its Atlas aortic grafts to accommodate a range of neck and landing-zone dimensions. Accurate, calibrated cross-sectional imaging is essential for sizing, oversizing, and defining adequate sealing zones before an endovascular repair.
