Abstract
A lumen stent () and an implant are provided. The lumen stent includes a tubular body (), an inner branch () and an outer branch () which are respectively communicated with the tubular body (). The tubular body () includes a first body segment (), a tapered segment () and a second body segment () which are connected in sequence. The tapered segment () is provided with an outer branch window () and an inner branch window (). The proximal end of the outer branch () is connected to the outer branch window (). The distal end of the inner branch () is connected to the inner branch window (). The area of the inner branch window () is larger than that of the outer branch window (). The beneficial effects are as follows: since the area of the inner branch window () is larger than that of the outer branch window (), most of blood flow can rapidly pass through the inner branch (), so that the blood flow pressure of the outer branch () is reduced, and the distal end of the outer branch () is prevented from tilting and touching an inner wall of a tumor cavity.
