The IBS Angel™ Iron Bioresorbable 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, that 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.
○ Backbone: Made from a nitrided iron-tube, with excellent mechanical properties (radial strength), which can provide effective support for blood vessels.
○ Zinc Buffer layer: Protect the iron backbone from degradation/corrosion during the early vascular recovery period (3-6 months)
○ Coating: Polylactic acid coating can provide an acidic environment to control the degradation of the scaffold.
○Radiopaque markers: Gold-radiopaque markers, enhance scaffold visibility and facilitate physicians to position the scaffold and observe during follow-up
○ Degradation: The degradation period is about 2-3 years. It provides effective support for 6 months after implantation. The scaffold starts to degrade around 3 months after implantation when the blood vessel recovers. And the scaffold will be absorbed by the body 2 years after implantation.
○ Re-intervention: Compared with permanent stents, the IBS 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.
