A tracheal tube assembly includes a connector body, a cannula extending from the connector body, and an insert that provides rigidity to the connector body and retains the cannula in the connector body. The cannula has an upper end that fits between conforming tapered sections of the connector body inner surface and the insert. The insert may include features to mitigate stress on and around any secondary lumens in the cannula wall. Because the wall is thinner at the site of a secondary lumen, the connector body insert may include a recess into which the cannula wall may expand. The recess may be aligned with the secondary lumen.

A nasal interface for a device that attached to a user's nose is described. The nasal interface is particularly adaptable for a CPAP device and includes a device body having air passages through the body terminating in a pair of end portions, with each end portion having at least one outlet in a first surface of the end portion and a nasal interface supported on the body, the nasal interface comprising a pair of nose buds having flared fittings at end portions thereof.

Certain embodiments are directed to the use of an airway device that allows for selective lobar isolation for the administration of drugs and biologies in liquid solution deeply into lung tissue, with simultaneous ventilation of the rest of the lungs. In addition, the novel airway device facilitates the performance of interventional bronchoscopy procedures such as biopsies, removal of foreign bodies, tumor debulking and placement of stents. The advantage of having separate ventilation and working channels allows continuous view and use of instruments without interruption necessary to remove structures from the airway.

A method and system for an endotracheal tube or tracheostomy a tube formed with a hole, a cuff connected to the tube and formed around the hole, and a skirt connected to the tube above the cuff and draped over the cuff. A coating of a hydrophobic, lipophobic, and oleophobic substance can be disposed on the interior and exterior surface of the tube, the cuff, and the skirt. A stylet and siring may be used to secure the skirt during in-sertion in a detachable fashion. The string is retractable on withdrawal of the stylet.

Devices, systems, and methods of facilitating airway management with reduced risk of release of droplets and aerosolized pathogens from the lungs of a patient are disclosed, including a bronchoscope adapter for an endotracheal tube, an endotracheal tube with integral bronchoscope adapter, an endotracheal intubation mask system, a laryngeal mask airway-specific mask system, and a quick-seal laryngeal mask airway-specific mask system.

A laryngeal mask airway device for insertion into a patient to provide an airway passage to the patient's glottic opening. The device includes an airway tube, a mask attached to the airway tube, a peripheral inflatable cuff, and an outlet for gas. The mask is attached to the airway tube for gaseous communication between the tube and an outlet. The device further includes an oesophageal drain that includes a conduit that extends from an inlet at the distal end of the mask to an outlet disposed outside the patient when the device is in place. The conduit includes a mask section and airway tube section, wherein the mask section is formed integrally in the material of the body of the mask.

A method for cerebral cooling is described using a cooling assembly, which includes first and second elongate tubular members adapted for insertion into a nasal cavity of a patient through the patient's nostrils. The elongate tubular members each have a proximal end, a distal end, a lumen extending therebetween, and a plurality of ports in fluid communication with the lumen. The cooling assembly also includes a manifold and a reservoir, which contains a pressurized fluid that includes a propellant having a boiling point less than 22 C. The elongate tubular members are inserted into the nasal cavity through the patient's nostrils and pressurized fluid is delivered onto a surface of the nasal cavity by infusing the pressurized fluid from the reservoir through the manifold, into the lumens and through the plurality of ports of the first and second elongate tubular members.

An endobronchial blocker includes an operation box, an extension tube, a ballon, an inflation module, and an elbow module. The extension tube is connected to the operation box. The extension tube has a first passageway and at least one second passageway therein. The ballon is disposed on one end of the extension tube and is in communication with the first passageway. The ballon is in a deflated state during movement. The inflation module is connected to the first passage for supplying a gas to the ballon. The elbow module is assembled to the operation box and includes a pulling means and a control handle. When in use, the control handle is operated to move the pulling means, enabling the extension tube to bend or straighten, thereby reducing the risk of surgical interruption due to poor quality of the left/right lung respiration.

An inflatable cuff for an endotracheal tube system has a sealing component that is one or a combination of (a) a proximal one-directional valve configured to deflect with underpressure during the intubation procedure and contact the tracheal wall of a patient to provide sealing, (b) a distal one-directional valve configured to deflect with overpressure during the intubation procedure and contact the tracheal wall to provide sealing; and (c) a cloud shape of the inflatable portion. The cloud shape is defined by at least one sealing section of the inflatable portion having a primary maximum inflated diameter and at least one non-sealing section of the inflatable portion having a maximum inflated diameter less than the primary maximum inflated diameter. The inflatable cuff may be inflatable by a ventilation tube. The system may include a cuff controller that senses airflow parameters and provides regulated flows of air during an intubation procedure.
