The present disclosure describes systems and methods that utilize a multi-lumen tube with an integral visualization apparatus, such as a camera. The multi-lumen tracheal tube system may include a camera apparatus that is positioned to facilitate left or right bronchial intubation. In addition, the camera apparatus may be a unitary assembly that functions to hold and position the camera relative to the tube and provides an acceptable profile for comfortable intubation. The camera apparatus may include additional components, such as integral light sources and flushing or cleaning devices to remove any buildup from the camera or optical components.

Multi-lumen tracheal tube with visualization device

Various embodiments of a tracheal tube having a shaped divider disposed therein for separation of a tracheal tube into multiple ventilation lumens are provided. In some embodiments, the divider divides a tracheal ventilation lumen from a bronchial ventilation lumen. In some embodiments, the shaped divider provides an irregular inner diameter that allows a relatively bulky device to be inserted into one or both lumens.

Dual-lumen tracheal tube with shaped lumen divider

An inflatable balloon cuff may be adapted to seal a patient's trachea when associated with an endotracheal tube. These cuffs may include indicia that facilitate attachment of the cuff relative to the tube to reduce manufacturing variability for such characteristics as rotational and length alignment. Such indicia may include protrusions that are formed in the wall of the cuff collars or may include visual indicators, e.g., colorimetric or shape-wise indicators. Cuffs with improved attachment relative to the tube may have increased sealing performance.

Medical device and technique for using the same

According to various embodiments, a tracheal tube may include a pressure monitoring lumen configured to provide information related to the pressure in the tracheal space. By measuring pressure in the lumen, a tracheal pressure may be estimated. The pressure monitoring lumen may be in fluid communication with a pressure transducer that provides pressure measurements. An opening of the lumen may be covered with a distal shoulder of an inflatable cuff.
