Recently, the innovative product "Aortic Covered Stent System" of Lifetech Scientific (Shenzhen) Co., Ltd. is approved by China NMPA.

This product is indicated for patients with Stanford Type B aortic dissection requiring revascularization of the left subclavian artery, with a proximal landing zone length ≥15mm. This product is the first active stent-graft system explicitly designed for chimney techniques Its aortic branch stent employs a dual-layer stent design with an outer skirt, which fills the gap between the stent and the vessel after deployment. This design is expected to prevent and reduce endoleaks, thereby lowering the risk of complications.

The NMPA will strengthen the post-marketing surveillance of the product to ensure the safe use of this medical device.
