The indication of the lBS Angel™ lron Bioresorbable Scaffold is to improve the lumen diameter of the ductus arteriosus of newborns and infants who require stent treatment, with reference vessel diameters of 2.25 mm to 4.25 mm and target segment length ≤ 35 mm.

The scaffold comprises a nitrided iron backbone, a zinc buffer layer, and a polymer coating layer. As an absorbable scaffold, it finishes degradation in 2-3 years while still maintaining its mechanical properties in the early stage, which can greatly reduce the possibility of vascular collapse. The degradation products have been verified by multiple institutions multiple times that they will not cause biological toxicity.

Furthermore, it is easy to re-intervention after restenosis.

Made from a nitrided iron tube with excellent mechanical properties(radial strength), which can provide effective support for blood vessels.

Protect the iron backbone from degradation/corrosion during the early vascular recovery period (3-6 months).

Polylactic acid coating can provide an acidic environment to control the degradation of the scaffold.

Gold-radiopaque markers enhance scaffold visibility and facilitate physicians positioning the scaffold and observing it during follow-up.

The degradation period is about 2-3 years. lt provides effective support for 6 months after implantation. The scaffold starts to degrade around 3 months after implantation when the blood vessel recovers. The scaffold will be absorbed by the body 2 years after implantation.

Compared with permanent stents, the lBS Angel™ scaffold is degradable, and re-intervention is feasible in the same position without causing harm or adding burden to the blood vessels or the human body.
