The IBS Titan™ Sirolimus-Eluting Iron Bioresorbable Peripheral Scaffold comprises a nitrided iron backbone, a pure zinc buffer layer, and a drug coating layer. As an absorbable scaffold, it is degradable while still maintaining its mechanical properties in a cycle of about 2-3 years, which is much longer than the degradation cycle of other BRSs that can make blood vessels have a higher patency rate and greatly reduce the possibility of restenosis or vascular collapse. The degradation products have been verified by multiple parties multiple times that they will not cause biological toxicity and can be implanted twice.
IBS Titan™ has a wider range of options than existing stents on the market, with a maximum length of up to 118mm, which can completely cover the lesion site while ensuring blood vessel patency.
○ Backbone: Made from a high-purity 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 and corrosion during the early vascular recovery period (6-12 months)
○ Coating: Polylactic acid coating + sirolimus to inhibit VSMC proliferation and reduce the risk of vascular restenosis
○ Degradation: The degradation period is about 2-3 years. It provides effective support 6 months after implantation and begins to degrade about 12 months later when the blood vessels have nearly recovered. 2 years after implantation, the scaffold is completely degraded.
○ Re-implantation: Compared with permanent stents, the IBS stent is completely degraded, and it can be re-implanted in the same position without causing harm or adding burden to the blood vessels or the human body.
