Publication number: 20110240032Abstract: Methods, apparatus, and kits for enhancing breathing in patients suffering from chronic pulmonary obstructive disease are described. The methods and apparatus rely on increasing flow resistance to expiration in a manner which mimics “pursed lip” breathing which has been found to benefit patients suffering from this disease. In a first example, a device is implanted in a trachea or bronchial passage to increase flow resistance, preferably selectively increase resistance to expiration relative to inspiration. In a second embodiment, a mouthpiece is provided, again to increase resistance to expiration, preferably with a lesser increase in flow resistance to inspiration. In a third embodiment, the patient's trachea or bronchial passage is modified by the application of energy in order to partially close the lumen therethrough.Type: ApplicationFiled: June 20, 2011Publication date: October 6, 2011Inventor: Rajiv Doshi

Publication number: 20110240038Abstract: Described herein are adhesive nasal devices. In particular, the adhesive nasal respiratory devices described herein are configured to be worn in communication with a subject's nasal cavity and may include a rim body having a passageway therethrough, an airflow resistor in communication with the passageway of the rim body, and a flexible, adhesive holdfast layer extending outward from the periphery of the rim body. The rim body region may be formed from multiple parts (e.g., a first and a second rim body region), and the airflow resistor may be secured between the parts forming the rim body. Methods of manufacturing and assembling these adhesive nasal devices are also described.Type: ApplicationFiled: June 20, 2011Publication date: October 6, 2011Inventors: Rajiv Doshi, Bryan Loomas, Ryan Kendall Pierce, Elliot Sather, Arthur G. Sandoval, Jeffrey W. Servaites, Sandrine Lebas, Matthew Durack

Publication number: 20110218451Abstract: Described herein are passive nasal device having a resistance to exhalation that is greater than the resistance to inhalation. Also described are devices, methods and systems for sensing and measuring intranasal pressure when a subject is wearing a passive nasal respiratory device that is configured to inhibit exhalation more than inhalation. Also described are adapters for nasal devices and methods of using a nasal device adapter. Adapters may be used so that a passive nasal device may be applied indirectly in communication with a subject's nose; in some variations this may allow the passive nasal device to be re-used. Also described herein are nasal devices having a billowing airflow resistor that is configured to have a greater resistance to exhalation than to inhalation.Type: ApplicationFiled: September 15, 2009Publication date: September 8, 2011Inventors: Danny Yu-Youh Lai, Arthur Ferdinand, Michael P. Wong, Elliot Sather, Rajiv Doshi, Bryan Loomas, Toru Mino, Jonathan Patrick Summers, Arthur G. Sandoval, Jonathan Downing, Jeffrey W. Servaites, Ryan K. Pierce, Motohide Hatanaka

Patent number: 7992564Abstract: Described here are devices for altering the flow of air in a respiratory cavity such as the mouth and nostrils of the nose. These methods and devices may be useful for affecting a physiologic benefit in patients suffering from a variety of medical diseases, particularly those that may benefit from “pursed-lip” breathing and non-invasive ventilation, such as COPD, heart failure, sleep apnea, and other medical disorders. The devices are typically removable devices that may be placed over or in a respiratory cavity to increase resistance to airflow within the respiratory cavity. Resistance to expiration may be selectively increased relative to inspiration. Removable oral and removable nasal devices are described. Oral and nasal devices that filter inhaled airflow of debris and allergens are also provided. A nasal device that increases patency of the nares is also provided.Type: GrantFiled: February 24, 2010Date of Patent: August 9, 2011Assignee: Ventus Medical, Inc.Inventors: Rajiv Doshi, Motohide Hatanaka, Robert A.
