Development of Bronchial Stent for High Ciliary Function in Respiratory Tract

Abstract

A balloon expandable tracheal stent is used to broaden the respiratory system, primarily to avoid tracheal rings from collapsing or causing central airway obstruction (CAO). The research relates to a stent that improves air flow in the "windpipe" or "trachea tract" by limiting the amount of surface area covered by the stent, allowing cilia to function normally. Furthermore, the stent decreases mucus collection and tissue granulation within the stent, which has improved anti-migration properties due to flare ends, is suited for custom size, and reduces the risk of airway perforation and erosion. A therapeutic substance is coated on the stent to avoid infection at the treatment site.
