Evaluation of the Feasibility, Safety, and Efficacy of Single-use Endobronchial Silicon Spigots for the Treatment of Refractory Pneumothorax

The single-use endobronchial silicon spigot is injection-molded from implant-grade silicone and has a solid conical body. The endobronchial silicon spigot is used for the temporary occlusion of the target bronchus. It is delivered to the target bronchus through a bronchoscope using biopsy forceps, and the position of the blocker is adjusted to occlude the responsible bronchus leading to the pleural air leakage.
