Patent number: 9033976Abstract: This relates to treating reversible chronic obstructive pulmonary disease, and more particularly, to exchanging energy with airway tissue such as that found in human lungs. This exchange of energy reduces the ability of the airways to constrict, reduces the resistance within the airway to the flow of air through the airway, reduces mucus plugging of the airways, and/or increases the airway diameter. This energy exchange also may reduce the ability of the lung to produce at least one of the symptoms of reversible obstructive pulmonary disease.Type: GrantFiled: May 16, 2013Date of Patent: May 19, 2015Assignee: Asthmatx, Inc.Inventors: Christopher J. Danek, Michael Biggs, Keith M. Burger, Bryan Loomas, Thomas Keast, Dave Haugaard

Patent number: 8465486Abstract: Methods and devices for treating reversible chronic obstructive pulmonary disease are disclosed, which include a device for delivering energy to a wall of an airway in a human lung. The device includes a flexible elongate body with a proximal portion, a distal portion, a distal end, and a lumen extending therebetween. The device also includes a deployment member having an electrically conducting wire extending from the proximal portion of the elongate body and extending through the lumen and terminating at a distal tip distal to the distal end of the elongate body. The device further includes an expandable basket having a plurality of curved electrode legs and a temperature sensing element coupled to the expandable basket.Type: GrantFiled: July 25, 2012Date of Patent: June 18, 2013Assignee: Asthmatx, Inc.Inventors: Christopher James Danek, Michael Biggs, Keith M. Burger, Bryan Loomas, Thomas Keast, Dave Haugaard

Patent number: 8257413Abstract: This relates to methods and devices for treating reversible chronic obstructive pulmonary disease, and more particularly, relates to a device for exchanging energy with airway tissue such as that found in the airway of human lungs. The exchange of energy with this airway tissue in the airways reduces the ability of the air ways to constrict and/or reduces the resistance within the airway to the flow of air through the airway. This also relates to a method for decreasing responsiveness or decreasing resistance to airflow of airways involves the transfer of energy to or from the airway walls to prevent or reduce airway constriction and other symptoms of lung diseases. The treatment reduces the ability of the airway to contract during an acute narrowing of the airways, reduces mucus plugging of the airways, and/or increases the airway diameter.Type: GrantFiled: September 22, 2006Date of Patent: September 4, 2012Assignee: Asthmatx, Inc.Inventors: Christopher James Danek, Michael Biggs, Keith M. Burger, Bryan Loomas, Thomas Keast, Dave Haugaard

Publication number: 20120123264Abstract: Devices and methods are disclosed for creating passages in tissue and detecting blood vessels in and around the passages. The devices may be used to create channels for altering gaseous flow within a lung to improve the expiration cycle of an individual, particularly individuals having Chronic Obstructive Pulmonary Disease (COPD). In addition, the devices may be used to sample tissue during biopsy or other medical procedures where perforating a blood vessel could result in injury to a patient.Type: ApplicationFiled: November 25, 2008Publication date: May 17, 2012Applicant: BRONCUS TECHNOLOGIES, INC.Inventors: Thomas M. KEAST, Dave HAUGAARD, Edmund J. ROSCHAK, Yaniv ROCK

Patent number: 7422563Abstract: Disclosed herein are devices for altering gaseous flow within a lung to improve the expiration cycle of an individual, particularly individuals having Chronic Obstructive Pulmonary Disease (COPD). More particularly, devices are disclosed to produce collateral openings or channels through the airway wall so that expired air is able to pass directly out of the lung tissue to facilitate both the exchange of oxygen ultimately into the blood and/or to decompress hyper-inflated lungs.Type: GrantFiled: February 21, 2002Date of Patent: September 9, 2008Assignee: Broncus Technologies, Inc.Inventors: Ed Roschak, Thomas Keast, Hewlett E. Melton, Jr., Christopher Lee Willink, Dave Haugaard, David Thompson
