  • Publication number: 20080178874
    Abstract: Described herein are adjustable whole-nose nasal devices having a first passageway for communication with a first nasal passage and a second passageway for communication with a second nasal passage, an airflow resistor that inhibits expiration more than inspiration, and an adjustable connector. The adjustable connector may include one or more adjustable joints or regions that allow the whole-nose device to conform to the spacing between a subject's nostrils, and/or the orientation and angle of the subject's nostrils. Also described herein are whole-nose devices having a single airflow resistor communicating with both of a subject's nasal passages. Methods of treating a disorder using the whole-nose nasal devices are also described.

  • Publication number: 20080173309
    Abstract: 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.

  • Publication number: 20080041373
    Abstract: 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.
