Abstract: Various embodiments of tracheal tube assemblies disclosed herein may include a tubular body having an open distal end for ventilating a patient and a cuff disposed around the tubular body above the open distal end. The cuff may be adapted to be inflated to seal the cuff against a wall of a trachea of the patient. The cuff may include a first portion that spaces the tubular body a first distance from the tracheal wall when inflated and a second portion that spaces the tubular body a second distance from the tracheal wall when inflated. The second distance may be greater than the first distance.

Abstract: Various embodiments of a tracheal tube having a tubular body with an open distal end and a tube wall with a variable thickness are provided. The tube wall may include a thickened section comprising a void. The tracheal tube may also include an offset ventilation lumen disposed in the tubular body and adapted to facilitate airflow to and from a patient. Embodiments of the tracheal tube may also include a suction lumen disposed in the thickened section of the tube wall and terminating in a port opening into the void for removal of secretions from the patient's trachea.

Abstract: Various embodiments of a medical device tube having scaffolding-supported inner and outer walls are provided. In particular, the medical device tube may include a plurality of struts extending from an inner wall to an outer wall of the medical device tube. In certain embodiments, each of the individual struts may connect to adjacent struts at the inner wall and the outer wall. As such, the plurality of struts may comprise a zigzag pattern circumferentially around the medical tube device. In other embodiments, the struts may extend radially from the inner wall to the outer wall of the medical tube device. Regardless, the area between the struts and the inner wall and/or the outer wall form a plurality of lumens, which may be used for suctioning, blowing, and various other applications of the medical device tube.

Abstract: Various embodiments of tracheostomy tube assemblies including a flange member having a variable volume are provided. The tracheostomy tube assemblies may include a cannula having a distal end and a proximal end. The distal end may be adapted to be inserted into a patient's trachea, and the flange member may be disposed about the proximal end of the cannula. The flange member is adapted to expand to a first volume and to contract to a second volume, the first volume being greater than the second volume.

Abstract: A tracheal dilator system and method of manufacture are provided, suitable for dilating a passageway into a patient airway. In one embodiment, a tracheal tube is provided. The tracheal tube includes a dilator retrieval tip disposed on a distal end of a tracheal tube cannula. The dilator retrieval tip is configured to retrieve a tracheal dilator configured to enter through the distal end of the tracheal tube and exit through a proximal end of the tracheal tube.

Abstract: A reverse dilator system and method are provided, suitable for dilating a passageway into a patient airway. In one embodiment, a tracheal intubation system is provided. The tracheal intubation system includes a reverse dilator. The reverse dilator includes a shaft and a resizable portion disposed on a distal portion of the shaft. The reverse dilator is configured to dilate a tracheal passageway leading into an airway from inside the airway.
