  • Patent number: 8163034
    Abstract: A localized pleurodesis for lung devices created utilizing a combination of a mechanical component and a chemical component. The chemical component is utilized to create an acute adhesion between the visceral pleural membrane and parietal pleural membrane while the mechanical component is utilized to create a chronic adhesion.
    Type: Grant
    Filed: February 21, 2008
    Date of Patent: April 24, 2012
    Assignee: Portaero, Inc.
    Inventors: Asia Chang, Don Tanaka
  • Patent number: 8062315
    Abstract: A variable parietal/visceral pleural coupling may be utilized to create an air-tight seal in the pleural space between the parietal and visceral pleura. This coupling may be utilized to create a seal for other implantable devices.
    Type: Grant

    Date of Patent: November 22, 2011
    Assignee: Portaero, Inc.
    Inventors: Walter J. Aster, Asia Chang, Don Tanaka
  • Patent number: 7931641
    Abstract: A visceral pleura ring connector that may be utilized to anchor and seal the visceral pleura to a conduit or other device entering the lung from a non-native airway. The visceral pleura ring connector may be positioned around the visceral pleura and an insertion device and seal them together without having to make any holes in the pleura. The visceral pleura ring connector may be utilized with a pulmonary pleural stabilizer to hold the visceral pleura of the lung during surgical procedures involving accessing the lung or lungs of a patient directly through the lung and not the native airways.

  • Publication number: 20100147294
    Abstract: A mechanical device and/or chemical process is utilized to maintain luminal patency in conduits or other devices implanted in the lung or lungs of a patient. The mechanical device and/or chemical process ensures that air flows freely through a conduit implanted through an anastomosis into a lung. The device is suitable for use in conjunction with ventilation bypass treatments for chronic obstructive pulmonary disease.

  • Patent number: 7726305
    Abstract: 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 one aspect of chronic obstructive pulmonary disease. The system includes a trap, a filter/one-way valve, an air carrying conduit and a retention device for securing system elements in position. The system also includes a flow restriction device for controlling the flow of air through the air carrying conduit.
