One embodiment of a nasal dilator comprises a pair of pads (100), supported by arms (110, 112) surrounding an air passage (115). Each arm has a bend portion (120) and a pad (121) that grips a wearer's septum (615). Leg portions (125, 125′) extend down from the arms and are connected by a bight that surrounds the wearer's columella (620). The dilator is installed by gripping an optional handle (130) or the bight and inserting the pads and the arms into both nostrils. The dilator is urged upward and inward until the inner side of the bight touches the wearer's columella. To remove the dilator, the user grips the handle or bight and gently pulls downward until the dilator is removed. In an alternative embodiment, optional cushions (102, 122) soften the contact points between the dilator and the user's nasal structures and can supply medications through the user's nasal membranes.

An improved treatment of obstructive sleep apnea is disclosed. A method and various device combinations are presented. The device combinations describe optimal adjustments to properly position a nasal pillow in each of a patient's nares. A novel swivel joint is described to which a nasal pillow is slip-fit over. The swivel joint prevents loss of a proper seal between the nasal pillow and nare which may otherwise occur as a result of head movement. Also presented is an improved obturator mouthpiece design which substantially eliminates air flow through the oral cavity resulting from leakage in the oropharynx.

A nasal cannula diffuses a gas stream to distribute the volume of the gas stream as it is delivered into a user's nostril. The nasal cannula can direct flow of gas, such as oxygen, away from the more sensitive nasal tissues. The nasal cannula can diffuse the gas flow out of a plurality of orifices formed in the nostril prongs of the nasal cannula device, rather than sending the entire volume of gas out of a single orifice, as is the case with conventional nasal cannula devices.

Methods and devices for maintaining nasal passages open after nasal surgery are provided. In some embodiments, the method of the present invention includes initially cleaning at least some of the bodily fluids from the nasal passages of a patient after the nasal surgery; providing a post-operative device having a first tubular member with a first proximal end and a first distal end, and a second tubular member with a second proximal end and a second distal end, where the first proximal end is connected to the second proximal end with a bridging member, and the post-operative device is splintless; inserting the first distal end and the second distal end into the nasal passages of the patient to a location where the first proximal end and the second proximal end each protrude beyond the nostril opening of the patient; and placing a packing material at least partially around each tubular member. In some embodiments of the present invention, a specialized speculum is provided to facilitate placing packing material around the tubular members of the medical device.

A device for relieving congestion in restricted nasal passages, by the dilation thereof with an internal prosthesis placed within the nasal passages of an individual. This prosthesis comprises an adjustable bow having a pair of appendages extending from each end thereof. A separate tensioning element engages complimentary features on/in the bow to limit flexure thereof, and thereby provide a counterforce to bending of the bow. Accordingly, when the bow is flexed or bent, the extent of flex or bending of the bow is constrained by the tensioning element. The combined effect of the natural recoil of the resilient bow from the distended to flat position, combined with the counter forces imparted to the bow by the tensioning element, causes each appendage on the end of the bow to exert a constant pressure within each nasal passage to maintain such passages in a relatively open position.
