This invention provides an iliac vein stent and its system. The iliac vein stent includes a main stent, an embedded branch, and a second branch. The main stent includes a main body and a first branch connected to the distal end of the main body. The embedded branch is folded and shaped and then placed within the main body, with a portion of its outer wall fixedly connected to the inner wall of the main stent. Compared to its natural state, the minimum distance between the embedded branch and the center of the main body is increased in the folded and shaped state. The second branch is embedded in the embedded branch and connected to the main stent. Because the embedded branch is folded and shaped and placed within the main body, the elastic recovery force of the embedded branch in the folded and shaped state is small or even negligible. When the compressed iliac vein stent is located within the sheath, the compressive and frictional forces between the embedded branch and the inner sheath core are reduced, effectively mitigating damage to the embedded branch from the inner sheath core.
