Can 3D-printed stents solve complex airway blockages?
NCT ID NCT02889029
First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time
Summary
This trial investigates whether custom-made stents, designed using 3D computer modeling and printing, can safely treat complex airway narrowing that standard stents cannot fit. Ten adults with symptomatic, anatomically complex airway stenosis will receive a personalized stent and be followed for six months to check for complications. The goal is to see if a perfect fit can reduce serious problems like stent movement or tissue damage.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- custom 3D-printed airway stents
- What this could lead to
- If successful, this approach could offer a safer, personalized treatment for people with complex airway narrowing that standard stents cannot address.
- What could go wrong
- This is a very small early feasibility study with only 10 participants, so results may not apply broadly. Custom stents also carry risks like migration, infection, or tissue overgrowth.
