One of the primary challenges in esophageal stent manufacturing is ensuring the device's biocompatibility and durability. Since stents are implanted within the human body, they must be made from materials that will not trigger an immune response or corrode over time. Additionally, the manufacturing process must produce stents that are flexible enough to navigate the bloodstream yet strong enough to support the artery walls.Regulatory compliance is not just a challenge, but a significant responsibility in stent manufacturing.
