Devices, methods, and systems are provided for sealing a lung region. The target lung compartment is accessed and isolated via an isolation catheter. Fluid is delivered into the target lung compartment such that the target compartment is pressurized and the fluid flows through the collateral flow channel. A sealing agent is injected into the isolated lung compartment such that the agent is carried by the fluid to the collateral flow channel, thereby sealing the collateral flow channel. Variables of air flow may be measured or analyzed prior to injection of the sealing agent, or the sealing agent may be introduced into the region after a suitable time has elapsed.

A cleaning device, system and method for use with an ETT or tracheostomy ventilation tube 60, a ventilator machine 900, a source(s) 602 of fluid (for example, pressurized or unpressurized) and a source(s) of suctioning 603 is disclosed. In some embodiments, the cleaning device is useful for cleaning an inner surface of the ventilation tube 60 and/or for preventing or hindering the accumulation of biofilm thereon. In some embodiments, it is possible to clean biofilm or any other material on the inner surface 201 by delivering fluid into an interior of the ventilation tube, wiping the tube interior with a width-expanded wiping element (e.g. an inflated balloon) by longitudinal motion of the wiping element, and suctioning material out of the ventilation tube ventilation tube.

A tracheal tube (e.g., an endotracheal tube) includes an inserting cannula (that may be able to swivel), and wherein the inserting cannula is connected to an elbow adaptor through a Bayonet Neill-Concelman (BNC) connection. The BNC connection may provide more secure connection of the corresponding components and may be able to withstand greater amounts of force exerted on them without becoming detached from each other. The elbow adapter may further be coupled to a pressure release valve that will alleviate pressure buildup within the tracheal tube.

Embodiments can provide an expandable nasogastric intubation assembly, comprising a tube subassembly and an expander subassembly, comprising an inflatable balloon comprising a proximal expander component section and a distal expander component section wherein the proximal expander component section is located between the proximal end of the intubation assembly and the distal expander component section; wherein the distal expander component section is located between the distal end of the intubation assembly and the proximal expander component section; wherein the inflatable balloon is coupled to the tube subassembly, the proximal expander component section is configured to be inflated from an injection of fluid into at least one first opening located in the second passageway, and the distal expander component section is configured to be inflated by the injection of fluid into at least one second opening located in the second passageway.

An oral or nasal endotracheal tube includes a tube part, a first balloon and a second balloon. The tube part extends along a direction with a tube shape and an end portion of the tube part is intubated into trachea. The first balloon extends with passing through the tube part, and expands or contracts a block cuff. The second balloon extends with passing through the tube part, and expands or contracts a guide cuff. The block cuff uniformly expands around the tube part and blocks the trachea after the tube part is intubated into the trachea. The guide cuff ununiformly expands around the tube part and guides the tube part to be intubated into the trachea.

A laryngeal mask airway (LMA) device includes a backplate, an inflatable balloon, an airway tube, and a non-inflatable skeleton, which extends anteriorly from the backplate, and which is shaped so as to define a skeleton anterior side that has a pre-formed shape. A distal end of an inflation tube is coupled in fluid communication with (i) an interior of the inflatable balloon for supplying air to the inflatable balloon, and (ii) at least a portion of the skeleton anterior side. The inflatable balloon is shaped so as to define an inflatable annular cuff which (a) covers at least a portion of the skeleton anterior side, and (b) has a cuff anterior side that is configured to form a seal around a laryngeal inlet of a patient when the inflatable annular cuff is disposed at an LMA-insertion location within a throat of the patient. Other embodiments are also described.

The present invention provides systems, methods, devices and kits for assessing the level of pulmonary disease in individual lung compartments. A lung compartment comprises a subportion of a lung, such as a lobe, a segment or a subsegment, for example. By measuring individual lung compartments, the level of disease of the pulmonary system may be more precisely defined by determining values of disease parameters reflective of individual subportions or compartments of a lung. Likewise, compartments may be separately imaged to provide further measurement information. Once individual compartments are characterized, they may be compared and ranked based on a number of variables reflecting, for example, level of disease or need for treatment. Such comparison may be aided by simultaneous display of such variables or images on a visual display. Further, the same tests may be performed on the lung as a whole or on both lungs and to determine the affect of the diseased lung compartments on the overall lung performance. In addition, the diseased lung compartments may be temporarily isolated and the measurement tests performed to determine the affect of the isolation on overall lung performance. As a result, the most beneficial treatment options may be selected.

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.

An endobronchial tube which contains an integrated camera and light source and a cleaning nozzle arrangement disposed within dedicated peripheral lumen within the tube's wall.

Systems, methods, and devices are disclosed for accurately detecting a position of an endotracheal tube by sensing patient anatomy surrounding the endotracheal tube. Systems of the present disclosure include an endotracheal tube having at least one sensor supported by the endotracheal tube configured to detect surrounding patient anatomy. A signal processing unit can receive data from the sensor and can at least one of (i) identify the detected patient anatomy, for example, vocal cords, (ii) determine a distance between the detected patient anatomy and a known point on the endotracheal tube, and (iii) verify a positioning of the endotracheal tube within a tracheal or esophageal lumen of the patient. In some embodiments, the system can include at least one inflatable component that can extend along an outer surface of the endotracheal tube and support the at least one sensor.
