Abstract
A luminal stent includes a tube body that can be compressed and expanded in the radial direction, and an anti-leakage structure. The tube body is divided by the anti-leakage structure into a first tube body positioned on one side of the anti-leakage structure, and a second tube body positioned on the other side of the anti-leakage structure, with at least part of the first tube body being encircled by the anti-leakage structure. In a compressed state, the maximum compression diameter of the anti-leakage structure and the first tube body encircled by the anti-leakage structure is greater than or equal to the maximum compression diameter of the second tube body.
