  • Publication number: 20090209936
    Abstract: A method for treating a pneumostoma by applying suction to the pneumostoma in order to remove solid or liquid discharge. A pneumostoma aspirator including a bulb or syringe is used to apply negative pressure to a tube which enters the pneumostoma. The pneumostoma aspirator may be used in conjunction with a pneumostoma management device. Alternatively, the pneumostoma aspirator may be used after the pneumostoma management device has been removed. The pneumostoma aspirator may also be used to introduce irrigation fluid into the pneumostoma and/or remove irrigation fluid and discharge from the pneumostoma.

  • Publication number: 20090209909
    Abstract: A percutaneous single-phase surgical procedure is disclosed for creating a pneumostoma to treat chronic obstructive pulmonary disease. A pneumostomy instrument is introduced percutaneously through the thoracic wall, parietal membrane, visceral membrane and into the parenchymal tissue of the lung. The pneumostomy instrument crosses the pleural cavity between the parietal membrane and visceral membrane there being no pleurodesis between the membranes prior to passage of the pneumostomy instrument. A pneumoplasty device at the distal end of the pneumostomy instrument displaces and engages the parenchymal tissue of the lung and the pneumostomy instrument is used to secure the lung and visceral membrane in contact with the parietal membrane and chest wall. The pneumostomy instrument is left in place while a pneumostoma tract heals and pleurodesis occurs between the pleural membranes surrounding the pneumostomy instrument.

  • Publication number: 20090209856
    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.

  • Publication number: 20090209970
    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.

  • Publication number: 20090205643
    Abstract: An accelerated two-phase surgical procedure is disclosed for creating a pneumostoma to treat chronic obstructive pulmonary disease. The first phase includes creation of a localized pleurodesis. The localized pleurodesis is created using chemical agents and/or mechanical fasteners to secure the visceral membrane to the pleural membrane. The second phase includes introduction of a surgical instrument into the lung via the pleurodesis to create the pneumostoma. The first and second phases are performed as parts of a single surgical procedure. The formation of a stable pleurodesis is to prevent pneumothorax during the procedure.

  • Publication number: 20090205647
    Abstract: A pneumostoma management system which includes a pneumostoma management device and a cover. The pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management device includes a hydrophobic filter and/or a one-way filter. The cover serves to protect the pneumostoma management device and/or provide a cosmetic skin to make the pneumostoma management device more acceptable to the patient and thereby encourage patient compliance with a pneumostoma treatment regimen.

  • Publication number: 20090205641
    Abstract: A pneumostoma management device for maintaining the patency of a pneumostoma while controlling the flow of gases and discharge through the pneumostoma. The pneumostoma management device includes a bulb connected to a tube which enters the pneumostoma. A flow control device regulates air flow in and out of the pneumostoma via the tube. A hydrophobic filter traps discharge in the bulb while allowing gases to escape.

  • Publication number: 20090205650
    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 flange attaches to the chest of the patient to secure the device in position. The pneumostoma management device also includes a tube which enters the pneumostoma to allow gases to escape the lung. The length of the tube is selected to match the dimensions of the pneumostoma of a patient. In order to manufacture devices having different tube lengths, the tube is formed at a longer length than required, cut to size and tipped. The tube may be formed by molding or extrusion.

  • Patent number: 7533667
    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.
