The present invention provides improved dual lumen endobronchial tube devices. The dual lumen endobronchial tube devices feature a universal design for left or right mainstem bronchus insertion. The dual lumen endobronchial tube devices also feature enhanced balloon cuff designs to minimize dislodgement while maintaining proper airway sealing. The present invention also includes water activated lubricious coating inside the shaft to reduce friction during insertion of a bronchoscope into the airway. The present invention also provides improved double clamps that prevent the accidental clamping of both tubes of a Y-adapter.

An airway device for human or animal use includes an airway tube having a first end and a second end, the first end of which is surrounded by a laryngeal cuff configured to fit over the laryngeal inlet of a patient when in situ. The first end of the airway tube is provided with an intubating ramp configured to direct a tube inserted through the airway tube into the laryngeal inlet of the patient when in situ.

Tracheal tube systems may include first and second tubes and an inflatable balloon. The first tube may be flexible and hollow and have first and second open ends. The inflatable balloon may be affixed to and circumferentially surround a portion of the first tube. The inflatable balloon may include an indentation sized and positioned to accommodate a portion of a second tube positioned therein, when the inflatable balloon is inflated. The second tube may be hollow and have a multiplicity of holes along a sidewall not in contact with the balloon. The second tube may be configured to be coupled to a suction device that creates a negative pressure in the second tube. When the tracheal tube system is inserted in a patient's trachea, the negative pressure in the second tube may act to remove, or suction out, fluids and other matter from the trachea.

Intubation devices and methods of intubating a patient are provided. The intubation devices include a laryngeal mask airway (LMA) component having a mask portion and a tube portion and an endotracheal tube (ETT) component positioned in the laryngeal mask airway (LMA) component having a translatable and/or rotatable endotracheal tube. The endotracheal tube can be translated and/or rotated by a manipulation rod extending through the laryngeal mask airway (LMA) component and mounted to the endotracheal tube (ETT). The intubation devices may include inflatable cuffs adapted to manipulate the positioning or orientation of the endotracheal tube and/or to seal openings about the endotracheal tubes. Various ports, passages, and conduits are provided to enhance the use and manipulation of the intubation device.

An artificial airway including: an airway tube including at least one airway conduit; an inflatable cuff mounted on a distal end of the tube; a support member extending into the cuff, the cuff having inner side walls, anterior walls and a posterior wall, the inner side walls being joined to the support member to define a recess which communicates with the airway conduit, the anterior walls and posterior wall, sealingly engaging, in use, about the glottic opening and posterior pharyngeal wall respectively of a patient.

An inflatable balloon cuff may be adapted to seal a patient's trachea when associated with an endotracheal tube. Configurations of these cuffs that include tapered regions with certain characteristics, such as cuff wall diameter and thickness, may provide improved sealing of the trachea.

An airway management device comprising a body having a proximal end for receiving an oxygen supply tube and an distal end for insertion into a trachea of a patient; said body including a linear portion adjacent to the proximal end and a curved portion adjacent to the distal end; said body including an external shell and having a first bore through said shell for receiving the oxygen supply tube; wherein flexural strength for said airway management device is provided by said shell.

Devices for cerebral and systemic cooling via a patient's nasopharyngeal cavity are described. Cooling assemblies include at least one elongate tubular member having first and second lumens, a source of liquid coolant, a gas source communicating with the first lumen, and a switch for alternately connecting the liquid coolant source to the second lumen. The first lumen transports a compressed gas and the second lumen transports a volatile liquid. The pressurized fluid may be a perfluorocarbon. The perfluorocarbon may be perfluorohexane, perfluoropentane, or 2-methyl-perfluoropentane. The gas may be air, oxygen, or a combination.

An artificial airway device 1 to facilitate lung ventilation of a patient, comprising an airway tube 2 including a lumen 3, a mask 4 at one end of the airway tube, the mask including a backplate 5 and having a peripheral formation 6 capable of forming a seal around the circumference of the laryngeal inlet, the peripheral formation surrounding a hollow interior space or lumen 7 of the mask and the airway tube 2 opening into the lumen of the mask 4, and a connector 8 disposed at the proximal end of the airway tube, the connector including a main bore 9 for passage of gas to the airway tube lumen 3, and a wall 10 defining a circumference and including a plurality of ports 12 to allow passage of gas to the main bore, at least one port 12 being disposed for circumferential rotational movement relative to the main bore 9.
