Endotracheal devices, systems, and methods of using the same for transpulmonary thermal transfer to, e.g., induce transpulmonary hypothermia and/or warming. The endotracheal devices may include first and second lumens extending through the endotracheal device along with insulation located in an interior of the tube of the endotracheal device to limit thermal energy transfer between fluids in the first and second lumens.

Devices, methods, and systems are provided for occluding a collateral flow channel between a target lung compartment and an adjacent lung compartment. A video-assisted thoracoscopic device is inserted into a thoracic cavity of a patient and positioned at a fissure between a target lung compartment and an adjacent lung compartment. A collateral flow channel between the target lung compartment and the adjacent lung compartment is then identified using the video-assisted thoracoscopic device and an agent is injected into the collateral flow channel, thereby reducing the collateral flow channel.

The present invention provides an oral device that is inserted into the mouth of a patient during sedation to minimize the risk of airway obstruction and method of use. The oral device comprises a mouthpiece. A gas inlet conduit, a gas outlet conduit, and a fluid outlet conduit are adjacent to the vestibular portion of the mouthpiece. The gas inlet conduit may be used to provide oxygen to the mouth of a patient. The gas outlet conduit may be used to remove end-tidal carbon dioxide from the mouth of a patient. The fluid outlet conduit may be used to remove fluid from the mouth of a patient. The oral device may also include a tongue stabilizer to minimize movement of the tongue. The mouthpiece may include fluid outlet ports to remove fluid from the mouth of a patient and an instrument passage to allow medical instruments to pass through the oral device.

Described is device designed to maintain an open airway for use in an anesthetized patient undergoing a medical procedure or surgery while affording oropharyngeal insufflation and expiratory monitoring of the patient. The device is fashioned as an intraoral bite block having one or two pre-formed conduits for insufflation or exhalation monitoring which are readily coupled to a conventional nasal cannula. Also described are a method of using the device, and a system for providing oral insufflation to an anesthetized patient using a bite block as described in combination with a conventional nasal cannula.

Devices, methods, and systems are provided for occluding a collateral flow channel between a target lung compartment and an adjacent lung compartment. A video-assisted thoracoscopic device is inserted into a thoracic cavity of a patient and positioned at a fissure between a target lung compartment and an adjacent lung compartment. A collateral flow channel between the target lung compartment and the adjacent lung compartment is then identified using the video-assisted thoracoscopic device and an agent is injected into the collateral flow channel, thereby reducing the collateral flow channel.

A pulmonary secretion clearing ventilation catheter and related airway management system is disclosed. The ventilation catheter has a double lumen portion which each lumen of the double lumen portion operably secured to an airway management system so that inspiratory fluid (air/oxygen mixtures, with or without added water vapor) is delivered to the distal end of the ventilation catheter through one of the two lumens and expired inspiratory fluid, pulmonary secretions, and pulmonary fluids are removed from the patent through the other lumen. The expiratory fluid pathway preferably includes a secretion collection system for removing the pulmonary secretions and the like from the pathway, thereby improving operation and safety of the system. An improved inflatable cuff is also disclosed that permits a slight air leakage in the pneumatic seal between the patient's lungs and the environment, thereby facilitating removal of pulmonary secretions from the patient's lungs.

A ventilator system includes inspiratory lumen(s) and expiratory lumen(s). Inspiratory lumen(s) provide inspiratory gas mixtures to patient's airways, for instance with separate inspiratory lumens providing inspiratory gas(es) to separate airways portions (e.g., separate lungs, bronchi, lobes). Expiratory lumen(s) evacuate expiratory gases from airways, for instance with separate expiratory lumens evacuating gases from separate airway portions. Separate lumen(s) for separate portions of airways functionally separates structural airway portions, and allows maintenance of near-continuous flow across the respiratory cycle. This can reduce dead space and clear disease-causative agent(s) suspended therein, improving outcomes and reducing cross-contamination between airway portions. The system allows for independent titration of PEEP, pCO.sub.2 and/or pO.sub.2 without permissive hypercapnia. The system can include PEEP protection mechanisms, enhanced suctioning, suctioning mode(s), real-time compliance measurements, automatic settings choice to operate within highest lungs compliance, improved tube and lumen airway insertion, threading lumens, mounting device(s) for threaded lumens, etc.

A ventilation catheter and airway management system is described to create conditions that tend to clear secretions during the normal conduct of ventilation by having an exclusive outflow channel and/or to use a programed cuff leak combined with PEEP to protect the airway. The secretion clearing endotracheal tube may include separate inflow and outflow paths as part of a double lumen, to facilitate breathing when placed in a patient. The double lumen portion intersecting to form a single lumen for protrusion into the intratracheal region allowing the new inspiratory fluid from the airway management system to flow into a patient and the used inspiratory fluid from the patient to flow back to the airway management system. A pharyngeal suction component removes fluid from the intratracheal region via periodic suctioning.

Devices, methods, and systems are provided for occluding a collateral flow channel between a target lung compartment and an adjacent lung compartment. A video-assisted thoracoscopic device is inserted into a thoracic cavity of a patient and positioned at a fissure between a target lung compartment and an adjacent lung compartment. A collateral flow channel between the target lung compartment and the adjacent lung compartment is then identified using the video-assisted thoracoscopic device and an agent is injected into the collateral flow channel, thereby reducing the collateral flow channel.

A connector is provided for coupling with an invasive patient interface for providing respiratory support to a patient. The connector comprises a connector body having: (i) an inlet port couplable with a flow source providing a flow of respiratory gas; (ii) a gases exit port; and (iii) a device port couplable with the invasive patient interface. The connector also has a lumen having a first end and a second end. The connector body defines a gas flow path between the inlet port and both the device port and the lumen first end and the lumen second end is disposed outside the device port. The lumen provides improved CO2 clearance. Some embodiments provide for gas sampling and/or variable expiratory resistance.
