1. What is the main advantage of the Poly-NTMA coating?
The Poly-NTMA coating applied via eG™ technology significantly enhances hydrophilicity (contact angle reduced from 92° to 11°) and reduces platelet adhesion. This improves biocompatibility, lowers thrombogenic risk, and supports faster endothelialization.
2. What vessel sizes is the device compatible with?
The AUCURA™ Coated Flow Diverter is indicated for vessels ranging from 2.0 mm to 6.0 mm in diameter.
3. Is the device visible under imaging during the procedure?
Yes. The device is braided from 20μm Cobalt-Chromium-Platinum (CoCrNi-Pt) DFT wire, which provides full-length radiopacity under fluoroscopy and other imaging modalities.
4. Can the device be recaptured after partial deployment?
Yes, the delivery system allows for up to 90% retrievability before full deployment, providing greater procedural control and safety.
5. How does the device affect blood flow in covered branch vessels?
In vitro simulations show that the device maintains 90.5% of branch vessel blood flow velocity, minimizing hemodynamic impact on adjacent branches.
6. What microcatheter is compatible with this flow diverter?
The device is compatible with 0.017″ microcatheters for diameters of 2–4 mm, enabling improved access to distal and tortuous vasculature.
7. How does the AUCURA™ compare to other flow diverters in terms of deliverability?
The optimized braid and hydrophilic coating reduce delivery force by 62% compared to some uncoated systems, enhancing pushability and trackability.
