Definition : Stents designed for deployment into the bronchi to provide support for and/or maintain patency within the respiratory tree. These devices may consist of a metallic (e.g., meshlike wire) or polymeric tube, and they are available in several different shapes (e.g., straight, bent) to adapt to particular sections of the bronchi and/or to prevent migration. The stent surface may be coated to give the stent special capabilities (e.g., water-repellant). These stents may be deployed using rigid or flexible bronchoscopes, according their shape and physical characteristics. Bronchial stents are used mainly to treat mainstem bronchial stenosis without carinal involvement caused either by benign diseases or malignant tumors and facilitate the flow of air into the lungs.
