A bronchus is a passage or airway in the respiratory system that conducts air into the lungs. The first bronchi to branch from the trachea are the right main bronchus and the left main bronchus, also known as the primary bronchi. These are the widest and enter the lungs at each hilum, where they branch into narrower secondary bronchi or lobar bronchi, and these branch into narrower tertiary bronchi or segmental bronchi. Further divisions of the segmental bronchi are known as 4th order, 5th order, and 6th order segmental bronchi, or grouped together as subsegmental bronchi. The bronchi when too narrow to be supported by cartilage are known as bronchioles. No gas exchange takes place in the bronchi.
Apparatus and methods of bioelectrical impedance analysis of blood flow
InactiveUS6095987AAccurately and non-invasively and continuously measuring cardiac outputCatheterSensorsBioelectrical impedance analysisCardiac pacemaker electrode
Apparatus and methods are provided for monitoring cardiac output using bioelectrical impedance techniques in which first and second electrodes are placed in the trachea and / or bronchus in the vicinity of the ascending aorta, while an excitation current is injected into the thorax via first and second current electrodes, so that bioelectrical impedance measurements based on the voltage drop sensed by the first and second electrodes reflect voltage changes induced primarily by blood flow dynamics, rather than respiratory or non-cardiac related physiological effects. Additional sense electrodes may be provided, either internally, or externally, for which bioelectrical impedance values may be obtained. Methods are provided for computing cardiac output from bioelectrical impedance values. Apparatus and methods are also provided so that the measured cardiac output may be used to control administration of intravenous fluids to an organism or to optimize a heart rate controlled by a pacemaker.

Apparatus and method for isolated lung access
Apparatus, systems, methods, and kits are provided for isolating a target lung segment and treating that segment, usually by drug delivery or lavage. The systems include at least a lobar or sub-lobar isolation catheter which is introduced beyond a second lung bifurcation (i.e., beyond the first bifurcation in a lobe of the lung) and which can occlude a bronchial passage at that point. An inner catheter is usually introduced through the isolation catheter and used in cooperation with the isolation catheter for delivering and / or removing drugs or washing liquids from the isolated lung region. Optionally, the inner catheter will also have an occluding member near its distal end for further isolation of a target region within the lung.

Disclosed are methods and devices for regulating fluid flow to and from a region of a patient's lung, such as to achieve a desired fluid flow dynamic to a lung region during respiration and / or to induce collapse in one or more lung regions. An identified region of the lung is targeted for treatment, such as to modify the flow to the targeted lung region or to achieve volume reduction or collapse of the targeted lung region. The targeted lung region is then bronchially isolated to regulate airflow into and / or out of the targeted lung region through one or more bronchial passageways that feed air to the targeted lung region. The bronchial isolation of the targeted lung region is accomplished by implanting a flow control device into a bronchial passageway that feeds air to a targeted lung region.

Methods, systems and devices for improving ventilation in a lung area
ActiveUS20050005936A1Facilitates of gas concentrationEasy pressure controlTracheal tubesOperating means/releasing devices for valvesDiseaseMechanical ventilation
Methods, systems and devices are described for new modes of ventilation in which specific lung areas are ventilated with an indwelling trans-tracheobronchial catheter for the purpose of improving ventilation and reducing hyperinflation in that specific lung area, and for redistributing inspired air to other healthier lung areas, for treating respiratory disorders such as COPD, ARDS, SARS, CF, and TB. Trans-Tracheobronchial Segmental Ventilation (TTSV) is performed on either a naturally breathing or a mechanical ventilated patient by placing a uniquely configured indwelling catheter into a bronchus of a poorly ventilated specific lung area and providing direct ventilation to that area. The catheter can be left in place for extended periods without clinician attendance or vigilance. Ventilation includes delivery of respiratory gases, therapuetic gases or agents and evacuation of stagnant gases, mixed gases or waste fluids. Typically the catheter's distal tip is anchored without occluding the bronchus but optionally may intermittently or continuously occlude the bronchus. TTSV is optionally performed by insufflation only of the area, or by application of vacuum to the area, can include elevating or reducing the pressure in the targeted area to facilitate stagnant gas removal, or can include blocking the area to divert inspired gas to better functioning areas.

Apparatus and methods for deactivating bronchial nerves and smooth muscle extending along a bronchial branch of a mammalian subject to treat asthma and related conditions. An electromechanical transducer (11) is inserted into the bronchus as, for example, by advancing the distal end of a catheter (10) bearing the transducer into the bronchial section to be treated. The electromechanical transducer emits unfocused mechanical vibratory energy of one or more ultrasonic frequencies so as to heat tissues throughout a relatively large target region (13) as, for example, at least about 1 cm3 encompassing the bronchus to a temperature sufficient to inactivate nerves but insufficient to cause rapid ablation or necrosis of organic tissues. The treatment can be performed without locating or focusing on individual bronchial nerves.

Visualizing different types of airway wall abnormalities
The invention relates to visualizing different types of airway wall abnormalities. A method for visualizing airway wall abnormalities includes acquiring Dual Energy Computed Tomography (DECT) imaging data comprising one or more image volumes representative of a bronchial tree. An iodine map is derived using the DECT imaging data and the bronchial tree is segmented from the image volume(s). A tree model representative of the bronchial tree is generated. Then, for each branch, this tree model is used to determine an indicator of normal or abnormal thickness. Locations corresponding to bronchial walls in the bronchial tree using the tree model are identified. Next, for each branch, the locations corresponding to bronchial walls in the bronchial tree and the iodine map are used to determine an indicator of normal or abnormal inflammation. A visualization of the bronchial tree may be presented with visual indicators at each of the locations corresponding to bronchial walls indicating whether a bronchial wall is thickened and / or inflamed.

Methods and devices for improving breathing in patients with pulmonary disease
Methods, apparatus, and kits for enhancing breathing in patients suffering from chronic pulmonary obstructive disease are described. The methods and apparatus rely on increasing flow resistance to expiration in a manner which mimics “pursed lip” breathing which has been found to benefit patients suffering from this disease. In a first example, a device is implanted in a trachea or bronchial passage to increase flow resistance, preferably selectively increase resistance to expiration relative to inspiration. In a second embodiment, a mouthpiece is provided, again to increase resistance to expiration, preferably with a lesser increase in flow resistance to inspiration. In a third embodiment, the patient's trachea or bronchial passage is modified by the application of energy in order to partially close the lumen therethrough.
