Abstract
The present invention relates to a stent which is inserted into a stenosed bile duct to enlarge the bile duct. The stent includes a plurality of hooks which extend outwards from the main body of the stent at a predetermined angle and are spaced apart from each other. Therefore, when the stent is inserted into the bile duct, the hooks that extend outwards from the main body at a predetermined angle are hooked to the inner surface of the bile duct, thus preventing the stent from slipping relative to the bile duct.
