Abstract: A minimally invasive lung reduction device which overcomes the disadvantages associated with treating chronic obstructive pulmonary disease by utilizing the phenomenon of collateral ventilation to increase the expiratory flow from a diseased lung. The device also provides a means for assisting in or facilitating pulmonary decompression to compress the diseased area or area of the lung or lungs to a smaller volume.
Abstract: Surgical instruments and techniques are provided for creating a pneumostoma through the chest wall into the lung of a patient. The pneumostomy instruments and techniques may be used to create a pneumostoma which allows gases to escape from the lung through the chest wall and thereby treat chronic obstructive pulmonary disease.

Abstract: A flexible pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management device includes a pneumostoma vent having a tube which enters the pneumostoma to allow gases to escape the lung, a flange and a filter/valve to control flow of materials through the tube. The flange is a thin flexible patch which conforms and attaches to the chest of the patient. The flange secures the tube in position in the pneumostoma.
Abstract: A two-phase surgical procedure is disclosed for creating a pneumostoma to treat chronic obstructive pulmonary disease The first phase is a procedure to induce creation of a localized pleurodesis and is preferably performed as an outpatient procedure. The second phase is a procedure to introduce a surgical instrument into the lung via the pleurodesis to create the pneumostoma. An interval of about one of more days between the first and second phases allows the formation of a stable pleurodesis to prevent pneumothorax during the procedure.

Abstract: A single-phase surgical procedure is disclosed for creating a pneumostoma to treat chronic obstructive pulmonary disease. In a single-phase technique the pleurodesis is formed at the same time as the pneumostoma and does not require a separate step. The thoracic cavity is accessed to visualize the lung, the pneumostomy catheter is inserted into the lung and then the lung is secured to the channel through the chest wall creating a sealed anastomosis which matures into a pleurodesis after the procedure.

Abstract: A pneumostoma assessment and treatment system includes methods and devices for aftercare of a pneumostoma. In particular, methods and devices are provided for standardized monitoring and assessment of pneumostoma patency thereby facilitating the establishment of standards-based protocols for pneumostoma management. Methods of standardized pneumostoma patency assessment includes the use of devices for raising alveolar pressure to a controlled repeatable pressure above ambient while analyzing gas flow through the pneumostoma. In response to an assessment the functionality of the pneumostoma, the tissues of the pneumostoma may be treated with a treatment device utilizing one or more different modalities to preserve or enhance the health and function of the pneumostoma.

A hydrophobic filter traps discharge in the bulb while allowing gases to escape.
Abstract: A long term oxygen therapy system having an oxygen supply directly linked with a patient's lung or lungs may be utilized to more efficiently treat hypoxia caused by chronic obstructive pulmonary disease such as emphysema and chronic bronchitis. The system includes an oxygen source, one or more valves and fluid carrying conduits. The fluid carrying conduits link the oxygen source to diseased sites within the patient's lungs. A collateral ventilation bypass trap system directly linked with a patient's lung or lungs may be utilized to increase the expiratory flow from the diseased lung or lungs, thereby treating another aspect of chronic obstructive pulmonary disease. The system includes a trap, a filter/one-way valve and an air carrying conduit. In various embodiments, the system may be intrathoracic, extrathoracic or a combination thereof. A pulmonary decompression device may also be utilized to remove trapped air in the lung or lungs, thereby reducing the volume of diseased lung tissue.
