Abstract
A novel two-layer endotracheal tube (ETT) cuff for the prevention of pneumonia is disclosed. The disclosed two-layer ETT comprises a standard HVLP cuff covered with a second layer of elastomeric material with a sterile gel inserted between the layers. The two-layer cuff forms no folds when inflated in the trachea and prevents leakage, substantially reducing the risk for pneumonia attributable to standard ETT cuffs.
