Patent number: 8163034Abstract: 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: GrantFiled: February 21, 2008Date of Patent: April 24, 2012Assignee: Portaero, Inc.Inventors: Asia Chang, Don Tanaka
-
Patent number: 8062315Abstract: 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: GrantFiled: February 12, 2008Date of Patent: November 22, 2011Assignee: Portaero, Inc.Inventors: Walter J. Aster, Asia Chang, Don Tanaka
-
Patent number: 7931641Abstract: 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.Type: GrantFiled: February 21, 2008Date of Patent: April 26, 2011Assignee: Portaero, Inc.Inventors: Asia Chang, Attila Meretei, Alex Nedvetsky, Don Tanaka

DEVICES AND METHODS TO MAINTAIN THE PATENCY OF AN OPENING RELATIVE TO PARENCHYMAL TISSUE OF THE LUNG
Publication number: 20100147294Abstract: 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.Type: ApplicationFiled: February 19, 2010Publication date: June 17, 2010Applicant: Portaero, Inc.Inventors: Asia Chang, Scott M. Russell, Don Tanaka -
