MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617090451 A) filed by Lifetech Scientific Shenzhen Co. , Ltd. on July 24, 2026, for Covered Stent And Stent Delivery System.
Inventors include Tang, Jiangfeng; and Tang, Benping.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: Provided are a covered stent (100) and a stent delivery system (200). The covered stent (100) comprises a main stent (10) provided with a tubular body. Along an axial direction, the main stent (10) comprises a proximal support section (1) and a tumor cavity covered section (3). The tumor cavity covered section (3) is internally provided with a first embedded stent (4) and a second embedded stent (5) arranged radially. The distal end of the tumor cavity covered section (3) is provided with an opening (32) communicating with the exterior. Distal openings of the first embedded stent (4) and the second embedded stent (5) both communicate with the opening (32). The first embedded stent (4) has higher support strength than the second embedded stent (5). By configuring the first embedded stent (4) with relatively high support strength, patency of an external iliac artery corresponding to the first embedded stent (4) is ensured at least when the covered stent (100) is compressed. Further, extended covered configurations of the first embedded stent (4) and the second embedded stent (5) can ensure sealing integrity at an attachment gap (4021) after being sutured to the main stent (10), thereby preventing endoleaks at the embedded stents.
