Recently, the innovative product "Grency® Iliac Vein Stent System" produced by Hangzhou Weiqiang Medical Technology Co., Ltd. is approved by China NMPA.

The product consists of a stent and a delivery device. The stent, which is pre-loaded within the delivery device, is a self-expanding nickel titanium alloy stent with tantalum markers for radiopacity. The delivery device consists of a sheath core, a sheath connector, a haemostatic valve, a handle and a rear handle. The product is sterilized by ethylene oxide and is intended for single use. This product is intended to be applied in the common iliac vein for the treatment of non-thrombotic iliac vein compression syndrome.

The stent features a proximal tapered and flared venous stent design, an open-loop midsection, and a segmented structure that enhances product properties to meet clinical needs.

The NMPA will strengthen the post-marketing surveillance of the product to protect the safety of medical devices used by patients.
