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.

A laryngeal mask airway device includes a flexible tube set and an annular mask. The flexible tube set has an airway tube and an air guide tube that are juxtaposed. The annular mask has an outer membrane surrounding an outer periphery of one end of the airway tube and an elastic filler disposed inside the outer membrane. The outer membrane is in communication with one end of the air guide tube. When in use, the outer membrane is first squeezed to compress the elastic filler, and then the other end of the air guide tube is closed. The inside of the outer membrane forms a negative pressure to maintain the elastic filler in a small volume, so that one end having the annular mask of the flexible tube set can be placed and positioned in a patient's throat.

The volume of a hyperinflated lung compartment is reduced by sealing a distal end of the catheter in an airway feeding the lung compartment. Air passes out of the lung compartment through a passage in the catheter while the patient exhales. A one-way flow element associated with the catheter prevents air from re-entering the lung compartment as the patient inhales. Over time, the pressure of regions surrounding the lung compartment cause it to collapse as the volume of air diminishes. Residual volume reduction effectively results in functional lung volume expansion. Optionally, the lung compartment may be sealed in order to permanently prevent air from re-entering the lung compartment. The invention further discloses a catheter with a transparent occlusion element at its tip that enables examination of the lung passageway through a viewing scope.

Certain embodiments include an endotracheal (ET) device assembly including an expansion lattice coupled with an expansion and/or contraction actuator. In certain aspects the expansion lattice is position within an open-ended sheath or cover that is position between the trachea and the expansion lattice when deployed.

Methods, systems, and devices are disclosed for providing selective and non-selective cooling and warming of a patient. Multiple embodiments of devices are disclosed for performing rapid induction and maintenance of therapeutic hypothermia either in a hospital setting or in the field so that hypothermic treatment can be quickly instituted before significant tissue damage occurs. Methods are also disclosed for targeting brain cooling by irrigating the upper airway, aerodigestive tract, and/or more generalized cooling by irrigating the esophagus and/or stomach.

A laryngeal mask is provided which has a mask body having a capsule body and a support body, wherein a groove is provided on the top of the support body, and the capsule body is correspondingly disposed on the groove; and a tube body having an airway tube body, wherein one end of the tube body is bonded to the support body, and the bonding portion is provided with an opening communicating with one end of the airway tube body.

An airway device for human or animal use comprising an airway tube having a distal end and a proximal end, the distal end of which is surrounded by a laryngeal cuff, adapted to fit anatomically over the laryngeal structure of a patient, wherein the device optionally further comprises a buccal cavity stabilizer located on or around the airway tube between the laryngeal cuff and the proximal end of the tube, said buccal cavity stabilizer being adapted to nest with the anterior aspect of the patient's tongue, the size, shape and configuration of the buccal stabilizer being adapted to prevent rotational or side-to-side movement of the airway device in use.

A tracheostomy tube assembly includes an outer tube (1) and an inner cannula (20, 120, 220 51, 61) inserted into and removable from the tube. The inner cannula has a constant internal diameter along its length and has at its patient end (22, 122, 222) a seal member (23, 123, 223) extending around the cannula. The seal member may be a separate ring 23 of resilient material attached to the outside of the shaft of the cannula or it may be formed of the material of the shaft (121, 221) itself. Alternatively, the seal member (50, 60) may be of a kind that expands when exposed to an elevated temperature or humidity, and may include a shape memory effect material.
