Abstract
Bioresorbable stents for treating airway disorders and methods of treatment of the airway disorders using the bioresorbable stents are disclosed. Once implanted, the stents stabilize or maintain an airway lumen. The radial strength of the stents decreases with time which allows the airway to adjust from being artificially supported to a healed state without artificial support. The stent may be removed from the airway through bioresorption without intervention. The bioresorbable stents include a bioresorbable body having a shape that conforms or is conformable to the shape of the of airway lumen.
