  • 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: 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: 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: 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.
