Since 2006, the R&D team has been deeply engaged in the research and development of iron-based bioresorbable materials and devices. By infiltrating about 0.05wt.% of nitrogen into high-purity iron, the iron alloy scaffold with a strut thickness of only 50 microns has obtained mechanical properties, clinical operation performance, and indication range comparable to mainstream permanent stents. At the same time, the team has created a unique design and technical solution for controlled degradation and drug release, breaking through the bottleneck of slow degradation of iron alloy materials in the body. Iron-based materials do not leave harmful substances after being completely absorbed by the human body. The degradation products have been tested to meet relevant standards. Therefore, iron-based scaffold is less damaging to the human body. Compared with other DES, iron-based scaffolds can provide more possibilities for restenosis and interventional remediation of blood vessels.
