Systems, methods and devices for performing pulmonary procedures, and in particular treating lung disease. A flow control element includes a valve that prevents airflow in the inhalation direction but permits airflow in the exhalation direction. The flow control element is guided to and positioned at the site by a bronchoscope that is introduced into the patient's trachea and used to view the lungs during delivery of the flow control element. The valve may include one, two or more valve elements, and it may be collapsible for easier delivery. A source of vacuum or suction may be used to increase the amount of fluid withdrawn from the lung tissue. A device for measuring hollow structures, such as bronchioles, and a device for removing a previously-placed flow control element are disclosed as well.

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.

A desired fluid flow dynamic to a lung region can be achieved by deploying various combinations of flow control devices and bronchial isolation devices in one or more bronchial passageways that communicate with the lung region. The flow control devices are implanted in channels that are formed in the walls of bronchial passageways of the lung. The flow control devices regulate fluid flow through the channels. The bronchial isolation devices are implanted in lumens of bronchial passageways that communicate with the lung region in order to regulate fluid flow to and from the lung region through the bronchial passageways.

One aspect of the invention relates to a hydrogel comprising a polymer comprising a plurality of pendent hydroxyl groups, a crosslinker, and a sclerosing agent. Another aspect of the invention relates to a method for reducing lung volume in a patient comprising the steps of advancing into a region of a patient's lung via said patient's trachea a multi-lumen catheter lumen through a bronchoscope; and co-administering, through the multi-lumen catheter, a first mixture comprising a first amount of a polymer containing a plurality of pendent hydroxyl groups; a second mixture comprising a second amount of a crosslinker; and a third mixture comprising a third amount of a sclerosing agent; thereby forming a hydrogel in said region. In certain embodiments, the compositions and methods described herein are intended for use in the treatment of patients with emphysema of the lung.

The present invention provides an endotracheal intubation assist instrument for inserting the bronchofiberscope from the oral or nasal cavity to the trachea easily and then inserting the endotracheal tube into the trachea easily. The side hole 20 is installed near the front edge of the guide tube 10. The guide tube 10 advances naturally from the oral cavity, and the front edge of the guide tube 10 reaches the entrance of the esophagus. The view field is obtained by putting the front edge of the bronchofiberscope 200 onto the base 21. The glottis can be found by the view field of the bronchofiberscope 200 while pulling back the guide tube 10 slowly. The path for the bronchofiberscope 200 from the oral cavity to the esophagus can be secured by the guide tube 10 without influence of the obstacles such as a tongue and an epiglottis, and the operatability can be enhanced. Only the guide tube 10 is removed and the bronchofiberscope 200 remains as the guide line for the endotracheal tube insertion. The endotracheal tube is inserted to the trachea by utilizing the bronchofiberscope 200 as the guide line.

Methods and devices are adapted 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. Pursuant to an exemplary procedure, an identified region of the lung is targeted for treatment. 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.

A retractable protective respiratory mask including disposable filters, which protects the respiratory system, covering the nose and mouth during inhalation while breathing in an atmosphere polluted by different agents, such as infectious, virulent, or pathogenic agents, or other toxic substances. The mask also protects non-infected persons from persons infected with a virus, as saliva and sputum expelled when coughing, breathing-out, and/or talking can be deposited inside the mask. The mask can include a collection-container filter, allowing a viral-infected wearer to breathe in a polluted atmosphere, to talk, to cough, to sneeze and/or to deposit saliva and sputum. The mask can be used as any other type of filter mask and/or disposable environmental air mask for industry in general, and also providing protection in rarefied natural atmospheres. The mask can be used as a container or packaging for drugs administered by means of bronchial airways, or as medical or rescue masks.
