An apparatus includes a shaft, an expandable dilation member, and a bulbous tip. The shaft has a first outer cross-sectional dimension. The dilation member is positioned proximal to the distal end of the shaft. The dilation member is operable to transition between a non-expanded configuration and an expanded configuration. The dilation member is sized to pass through a passageway associated with drainage of a paranasal sinus or a Eustachian tube when the dilation member is in the non-expanded configuration. The bulbous tip is positioned at the distal end of the shaft. The bulbous tip is distal to the dilation member. The bulbous tip has a second outer cross-sectional dimension. The second outer cross-sectional dimension is larger than the first outer cross-sectional dimension. The bulbous tip is removably secured to the distal end of the shaft.

A nasal fluid-spray device having: a reservoir containing at least one dose (D) of fluid; and a dispenser system that, each time the device is actuated, sprays a dose (D) of fluid through a spray orifice, generating a spray that extends axially from the spray orifice. The device further includes a generator system for generating a secondary flow, which generator system is actuated simultaneously with the dispenser system, the secondary flow generator system having a secondary flow channel provided with an outlet orifice, the outlet orifice arranged downstream from the spray orifice, and the secondary flow extending from the outlet orifice along an axis (B) that forms an angle (α) relative to the axis (A) of the spray and that intersects the axis (A), thereby deforming and/or deflecting the spray.

A therapeutic device for treating one or more conditions associated with a user's nasal cavities, sinuses, and/or ear canals includes a housing having an opening, an acoustic vibrator within the housing that is operable to provide an acoustic vibration to the user, a fan within the housing that is operable to provide a pressure to the user and a power supply that provides power to the acoustic vibrator and the fan. A mask is connected to the housing at the opening and includes a nasal interface appliable around the nose of the user, a nasal chamber in which the user's nostrils are located and an aperture through which the fan delivers the pressure.

An illuminating wire medical device may include an elongate flexible housing and an illuminating fiber and a core wire extending through at least part of the housing, the core wire providing desired pushability and torquability. The illuminating device may further include a connector assembly cooperating with the illuminating fiber to accommodate changes in length and to absorb forces applied during use of the device.

A system for manipulating a guide catheter within a patient's nasal passages or sinus cavities includes a guide catheter formed from an elongate flexible member having a lumen passing there through. A wire guide is slidably disposed within the lumen of the guide catheter. The system further includes a steering member fixedly secured to a proximal end of the wire guide and a proximal hub secured to a proximal end of the guide catheter. The system further includes a recessed handle having a first recess for fixedly receiving the proximal hub of the guide catheter and a second recess for receiving the steering member, the second recess being dimensioned to permit axial and rotational movement of the steering member while disposed in the second recess.

For the treatment of the upper respiratory system is used sea water due to its due to its anaplastic, healing and hypertonic (osmosis) characteristics, deriving if it stays for adequate time inside the nasal conchas and nose cavities. This invention for its accomplishment, guarantees a stable column of water for adequate period of time in the nasal cavities and by the ingestion (Valsava) the water is pushed in the nasal conchas and the ducts of the nose sinuses and cavities and is consisted of Central storehouses (1) having a movable pin (4) with manually-operated provides water via the pipe (5) in the mouth (8). The central pipe (5a) provides the water to the nose and the small pipe (5b) to the periphery of the mouth (8) that expands it for its sealed application and is based in two edges (10). Alternatively the pipes (5) and the mouths are joined by one (5c) which is adapted in the entrance (12) of the bag (1a) with a pin (13), moved by electricity (13) or manually-operated.

Devices, systems, and methods for treating chronic rhinosinutisits (CRS) are described herein. The devices can have a guide member defining at least one lumen therethrough. A drug delivery component is advanced through the lumen to deliver a substance to the sino-nasal cavity of a patient. Once the drug delivery component is positioned at the desired area in the sino-nasal cavity, a user actuates the system to deliver the substance to the target area. Actuation of the system delivers the substance to the middle meatus, osteo-meatal complex, or other areas within the sino-nasal cavity of the patient.

A method of treatment and delivery device for mixed carbon dioxide, carbonic acid, saline and optional active additives for treating head ailments includes delivery of dosage of the treatment at specified flow rates, using a) main housing having a hollow central area containing the dosage; b) a dosage dispenser head located at the distal end of the main housing, and having at least one flow channel for movement of the dosage from the main housing through the dosage dispenser head and to external of the dosage dispenser head; c) a dosage release control component located between the main housing and the dosage dispenser head to permit flow of the dosage through the dosage dispenser head in response to increased pressure against the dosage; and d) a pressure-changing moveable component on the main housing.

This disclosure describes, inter alia, materials, devices, kits and methods that may be used to treat chronic sinusitis.

An insertion method includes: specifying a part of a mucous membrane which lies between a nasal cavity and a maxillary sinus and which is located in a space surrounded by an inferior nasal concha, a lacrimal bone, an ethmoid bone, and a palatine bone, as an opening formation position where an opening connected to the maxillary sinus is formed; forming the opening at the opening formation position; and inserting a medical device into the maxillary sinus through the formed opening.
