The S Discovered model is one of the most versatile and widely used stents. It is designed with a braided nitinol structure that provides excellent radial force, high flexibility, and resistance to external compression. Its open-cell design allows for maintaining effective biliary drainage in malignant or benign obstructions, while its S-shaped configuration facilitates precise anatomical adaptation, especially in distal lesions. It is highly compatible with “stent-in-stent” techniques, and its ergonomic delivery system allows for smooth placement both endoscopically and percutaneously. Its clinical reliability makes it the first choice in many hospitals with high complexity.
