Publication number: 20140128761Abstract: Described herein are passive nasal respiratory devices, in particular, passive nasal respiratory devices configured to achieve positive end-expiratory pressure (PEEP) in a subject wearing the device. PEEP devices may have a threshold pressure for opening during expiration. These devices may include a flap valve that opens on inhalation nested with a spring valve that opens when exhalation pressure exceeds a predetermined threshold. The device may be configured to be comfortably worn by a sleeping subject.Type: ApplicationFiled: November 4, 2013Publication date: May 8, 2014Inventors: Benjamin K. CLINE, Ronald G. FRENCH, Frank W.

Patent number: 8707955Abstract: 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: GrantFiled: June 20, 2011Date of Patent: April 29, 2014Assignee: Theravent, Inc.Inventor: Rajiv Doshi

Publication number: 20140109907Abstract: Described herein are combined active PAP/passive EPAP interface devices to transmit positive air pressure from a PAP source to the user, but provide passive EPAP when the PAP source is disabled. These interface device may continue to provide benefit to the user even if the PAP source becomes disconnected or otherwise fails. The interface devices described herein include a passive EPAP airflow resistor configured to provide expiratory positive airway pressure (“EPAP”). These interface devices may also include quick connects and/or disconnects for releasably connecting to the source of pressurized breathable gas, a quick release for disconnecting from the source of pressurized breathable gas, and an adhesive user interface region that connects the device the user's face. Also described are adapter for converting a PAP interface devices into combined active PAP/passive EPAP interface devices, and methods of using these devices.Type: ApplicationFiled: December 27, 2013Publication date: April 24, 2014Inventors: Rajiv DOSHI, Arthur FERDINAND, Elliot SATHER, Michael L.

Patent number: 8365736Abstract: 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: September 16, 2010Date of Patent: February 5, 2013Assignee: Ventus Medical, Inc.Inventors: Rajiv Doshi, Motohide Hatanaka, Robert A.

Publication number: 20120285470Abstract: Described herein are nose-reduced nasal devices configured to reduce or eliminate the unwanted noises associated with use of a nasal device. These noise-reduced nasal devices include a flap-valve airflow resistor and a noise-reduction feature that is a noise-reduction element, a noise-reduction flap valve, or both. The noise-reduction feature typically prevents the flap valve from oscillating or vibrating and producing an audible sound during use, particularly during inhalation through the device. The method and devices described herein may prevent the flap, and particularly the edge region of the flap face or tip of the flap, from oscillating during inhalation.Type: ApplicationFiled: March 17, 2009Publication date: November 15, 2012Inventors: Elliot Sather, Toru Mino, Arthur Ferdinand, Arthur G. Sandoval, Jeffrey W. Servaites, Jonathan P. Summers, Shapour Golzar, Rajiv Doshi

Patent number: 8302607Abstract: Whole-nose nasal respiratory devices and methods of making and using whole-nose nasal respiratory devices are described and illustrated herein. These devices are typically configured to be adhesively secured to a subject so that they engage both of the subject's nostrils and allow airflow from both nostrils to communicate with an airflow resistor. The airflow resistor is configured so that it inhibits exhalation through the nostrils more than it inhibits inhalation through the nostrils.Type: GrantFiled: November 17, 2011Date of Patent: November 6, 2012Assignee: Ventus Medical, Inc.Inventors: Ryan Kendall Pierce, Bryan Loomas, Rajiv Doshi, Jonathan P.
