Self-expanding biliary metal stent (SPAXUS)

The SPAXUS model is a covered metallic stent with a bell-shaped design at both ends, ideal for draining pancreatic or biliary collections adjacent to the gastrointestinal tract. Its self-expanding design provides a solid anchor to prevent migration and content leakage. While primarily used in EUS-guided procedures, it has also proven effective in complex biliary bypasses. Its flared structure ensures secure apposition between cavities, facilitating the passage of endoscopes or accessories if necessary. It is an effective solution for minimally invasive approaches in highly complex clinical scenarios.
