MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617090455 A) filed by Lifetech Scientific Shenzhen Co. , Ltd. on July 24, 2026, for Covered Stent And Delivery System.
Inventors include Xu, Yang; and Tang, Jiangfeng.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: Provided in the present invention are a covered stent and a delivery system. The covered stent comprises a main stent having a tubular main body and an embedded stent. The main stent comprises a proximal section, an aneurysm sac section and a distal section in the axial direction. The aneurysm sac section comprises a first channel and a second channel which are arranged in the radial direction, the second channel communicating with the distal section, and the first channel being provided with an opening at the distal end and being internally provided with the embedded stent. The provision of the embedded stent provides a channel for implantation of an internal iliac artery stent, so as to enable the internal iliac artery stent to have better anchoring performance, wherein the total scaffolding strength of the first channel and the embedded stent is smaller than that of the second channel, and since the second channel has the higher scaffolding strength, the first channel deforms before the second channel when the covered stent is subjected to compression, so as to enable the second channel to keep a better channel form, thereby preventing compression- induced occlusion and ensuring blood to smoothly pass through the second channel.
