Custom 3D stents aim to make breathing easier and safer
NCT ID NCT04848025
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests custom-made 3D-printed stents for people with narrowed airways. The stents are designed to fit each person's unique airway shape, which may reduce serious complications like stent movement or blockage. About 30 adults with severe symptoms will receive the stent and be followed for one year to see if breathing and quality of life improve.
