  • Publication number: 20090205658
    Abstract: A pneumostoma management system includes a pneumostoma management device for maintaining the patency of a pneumostoma and a drug delivery device for pneumostoma care. The drug delivery device includes a therapeutic agent dispenser for supplying a therapeutic agent and a propellant at positive pressure, a tube for entering the pneumostoma and a limiting device for limiting the depth of insertion of the tube into a pneumostoma. The drug delivery device may be used to introduce therapeutic agents into the pneumostoma for direct treatment of the pneumostoma, treatment of the lung by way of collateral ventilation, and/or treatment of non-lung tissues by diffusion into the bloodstream.

  • 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: 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: 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: 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: 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.

  • Publication number: 20090205645
    Abstract: A method for maintaining the patency of a pneumostoma while controlling the flow of material through the pneumostoma. A pneumostoma management system includes a two-part pneumostoma management device and associated insertion and removal tools. The pneumostoma management device includes a pneumostoma vent and a chest mount for positioning and securing the vent into a pneumostoma. To use the system, the chest is first cleaned and the chest mount secured to the chest adjacent the pneumostoma. The pneumostoma vent is then inserted into the pneumostoma through an aperture in the chest mount until it is engaged and secured by a coupling of the chest mount. The pneumostoma vent may be replaced periodically such as daily. The chest mount may be changed less frequently such as weekly.

  • 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.
