Multiple shapes and sizes for high intra-luminal compatibility: 3 shapes and 12 sizes to meet clinical needs Long-lasting support, fully degradable: PLA-hydroxyacetic acid copolymer is fully degradable to water and carbon dioxide in 3 months to avoid inflammatory reactions. 

Exclusive design, optimized material: Multi-crossing point design, combining flexibility and support, better adherence to the wall. The filament formula keeps the physical form more stable and facilitates support. 

Simple operation and short learning curve: faster and more efficient contraction of the stent and blue visualization of the end of the delivery device for more precise operation. 

Advanced technology, safer and more effective: lower postoperative intervention rate and longer stent support with comparable products in controlled clinical trials. 

Combination of drug and device, long-lasting and slow release: drug loading capacity of 1500 μg, precise drug release, safe, continuous and stable in vivo study of drug release characteristics in animals.
