Nasal respiratory devices
First Claim
1. A nasal respiratory device for use while sleeping and adapted to be secured so that it is disposed at least partially outside of a subject'"'"'s nasal cavity, the device comprising:
- an opening configured to communicate with the nasal cavity;
an airflow resistor in communication with the opening, wherein the airflow resistor is configured to increase the resistance to air exhaled through the opening to be more than the resistance to air inhaled through the opening; and
a shapeable holdfast configured to seal and to secure the nasal respiratory device so that the device is disposed at least partially outside of the subject'"'"'s nasal cavity.

Abstract
Described here are methods, devices, and kits for altering the flow of air in a respiratory cavity such as the 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 nasal devices are described.

22. A nasal respiratory device for use while sleeping and adapted to be secured over a subject'"'"'s nasal cavity, the device comprising:
-
an opening configured to communicate with the subject'"'"'s nasal cavity; an airflow resistor in communication with the opening, wherein the airflow resistor is configured to increase the resistance to air exhaled through the opening to be more than the resistance to air inhaled through the opening; and an adhesive holdfast configured to attach and seal the nasal respiratory device around the opening of a single nostril. - View Dependent Claims (23, 24, 25, 26)

27. A nasal respiratory device for use while sleeping and adapted to be secured so that it is disposed at least partly outside a subject'"'"'s nasal cavity, the device comprising:
-
a passageway configured to communicate with a subject'"'"'s nasal cavity; a rim having sufficient strength to support the passageway in the open state when the nasal respiratory device is inserted into the nasal cavity; an airflow resistor in communication with the passageway, wherein the airflow resistor inhibits exhalation more than inhalation; and a compressible holdfast to seal and secure the nasal respiratory device so that the device is disposed at least partly outside a subject'"'"'s nasal cavity, wherein the holdfast comprises a compressible material. - View Dependent Claims (28, 29, 30)

31. A nasal respiratory device for use while sleeping and adapted to be secured at least partially outside a subject'"'"'s nasal cavity comprising:
-
an opening configured to communicate with the nasal cavity; an airflow resistor in communication with the opening configured to increase the resistance to air exhaled through the opening to be more than the resistance to air inhaled through the opening; and an adhesive holdfast configured to attach and seal the nasal respiratory device around the opening of a single nostril without covering the subject'"'"'s mouth.
