Embodiments are directed to an endotracheal intubation system that provides for differential ventilation of lungs and lung lobes.

Methods and systems for targeting, accessing and diagnosing diseased lung compartments are disclosed. The method comprises introducing a diagnostic catheter with an occluding member at its distal end into a lung segment via an assisted ventilation device; inflating the occluding member to isolate the lung segment; and performing a diagnostic procedure with the catheter while the patient is ventilated. The proximal end of the diagnostic catheter is configured to be attached to a console. The method may also comprise introducing the diagnostic catheter into the lung segment; inflating the occluding member to isolate the lung segment; and monitoring blood oxygen saturation. The method may further comprise introducing the diagnostic catheter into the lung segment; determining tidal flow volume in the lung segment; determining total lung capacity of the patient; and determining a flow rank value based on the tidal flow volume of the lung segment and the total lung capacity.

Techniques for single lung ventilation (SLV) include a hollow main tube with outer diameter sized to fit inside a bronchus of a patient. The length of the main tube is sufficient for a distal end of the main tube to reach a first side bronchus from a proximal end configured to be located in a vicinity of a mouth of the patient. The hollow main tube has a ventilating orifice separated from the distal end at a location that corresponds to a different second side bronchus. A hollow tubular sleeve is moveably disposed inside and longitudinally aligned with the main tube. The sleeve is configured to be positioned in at least two positions: a first position that does not block the ventilating orifice; and, a second position that does block the ventilating orifice.

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.

The present disclosure relates generally to medical devices and, more particularly, to medical devices with electrical connectors. In one embodiment, a medical device may include a medical connector having one or more contacts configured to enable communication between the medical device and a medical monitor according to a Universal Serial Bus (USB) standard. The medical connector may also include an interface region disposed at least partially about the one or more contacts. The interface region may be configured to physically couple to a mating connector of the medical monitor. Additionally, the interface region may include a geometry or a dimension that does not comply with the USB standard.

A treatment system delivers a breathing gas and frozen ice or other particles (FSP) to a bronchus of a lung of a patient in order to induce hypothermia. The breathing gas and the FSP are usually delivered through separate lumens. Clogging of an FSP lumen can be inhibited by heating and/or cooling of the lumen. The temperature of exhaled gases or a body temperature may be measured, and a controller can adjust the duration or rate at which the ice particles are delivered in order to control the patient's core temperature based on the measured temperature.

A single lumen endobronchial tube for selective mechanical ventilation of the lungs can include a medical tube having a single lumen with an opening at each of opposed distal and proximal ends of the tube, the opening at the proximal end of the tube being adapted for connection to an external mechanical ventilation device, and the opening at the distal end of the tube being adapted for delivery of a medical gas; a wall extending throughout the tube's entire length having an internal wall surface, an external wall surface and a thickness therebetween, a portion of the wall having an aperture and a shaft adapted to house a mechanism for sealing the aperture; a distal bronchial cuff positioned along the external wall surface and adapted to expand radially outward; and at least a first proximal tracheal cuff positioned along the external wall surface and adapted to expand radially outward.

A method and system for instilling a medium into portions of a luminal network is provided. The method includes generating a model of a luminal network based on images of the luminal network, determining a location of a treatment target in the luminal network, navigating a bronchoscope through the bronchial tree to a target, guiding a catheter through the bronchoscope, dispensing medium to the target from a distal end of the catheter, and removing a quantity of medium from the luminal network.

Concepts presented herein include an apparatus for monitoring EMG signals of a patient's laryngeal muscles. The apparatus includes an endobronchial tube having an exterior surface and two lumens for providing ventilation. Conductive ink electrodes are formed on the exterior surface of the endobronchial tube. The conductive ink electrodes are configured to receive the EMG signals from the laryngeal muscles when the endotracheal tube is placed in a trachea of the patient. At least one conductor is coupled to the conductive ink electrodes and is configured to carry the EMG signals received by the conductive ink electrodes to a processing apparatus.

An airway manifold includes a manifold body having an upper body portion and a lower body portion. The body portions are engaged such that the upper body portion is rotatable relative to the lower body portion, whereby a generally hollow interior space is defined. The lower body portion has a port open to the interior space, and the upper body portion includes a plurality of ports open to the interior space. A first upper body port is axially alignable with the lower body port to define a substantially linear passageway therebetween when the upper body portion is at a first rotatable position relative to the lower body portion. A second upper body port is axially alignable with the lower body port to define a substantially linear passageway therebetween when the upper body portion is at a second rotatable position.
