Zhitong Financial APP News, Xianjian Technology (01302) announced that on November 23, 2021, the Yuranos independently developed by the GroupTMThe abdominal aorta covered stent system was registered and approved by the State Drug Administration of China.
It is understood that YuranosTMIt is used for the treatment of infrarenal abdominal aortic aneurysm. Compared with the same type of products, it is suitable for more complex clinical morphology, can meet the more extreme clinical anatomical structure, and has a wider range of indications: the minimum neck length of abdominal aortic aneurysm is 10mm, and the maximum infrarenal angle is 75 °. The instrument is a split design, including abdominal aortic bifurcation stent system and iliac artery extension stent system. Each system consists of a stent and a conveyor. The stent is composed of a nickel-titanium skeleton and a PET film. Each stent is loaded in its own conveyor, which is transported and released to the predetermined position during the operation.
At the same time, the instrument has a unique design, which can effectively improve the intraoperative and long-term treatment effect and reduce the risk of surgical complications: abdominal aorta bifurcation stent covered proximal naked segment inverted thorn and closed loop mini support wave design, increase stent anchoring, adhesion and flexibility, effectively prevent displacement and type I internal leakage; iliac artery extend stent inverted stab design, enhance the connection between components, and effectively prevent type III internal leakage caused by component shedding. The post-release function of the conveyor cooperates with the anchoring design of the stent assembly to achieve accurate positioning and regulation, and further improve the availability of instruments and the success rate of immediate operation.
