Sinusitis, mucocysts, tumors, infections, hearing disorders, choanal atresia, fractures and other disorders of the paranasal sinuses, Eustachian tubes, Lachrymal ducts and other ear, nose, throat and mouth structures are diagnosed and/or treated using minimally invasive approaches and, in many cases, flexible catheters as opposed to instruments having rigid shafts. Various diagnostic procedures and devices are used to perform imaging studies, mucus flow studies, air/gas flow studies, anatomic dimension studies and endoscopic studies. Access and occluding devices may be used to facilitate insertion of working devices such asendoscopes, wires, probes, needles, catheters, balloon catheters, dilation catheters, dilators, balloons, tissue cutting or remodeling devices, suction or irrigation devices, imaging devices, sizing devices, biopsy devices, image-guided devices containing sensors or transmitters, electrosurgical devices, energy emitting devices, devices for injecting diagnostic or therapeutic agents, devices for implanting devices such as stents, substance eluting or delivering devices and implants, etc.

Devices, systems and methods useable for dilating the ostia of paranasal sinuses and/or other passageways within the ear, nose or throat. A dilation catheter device and system is constructed in a manner that facilitates ease of use by the operator and, in at least some cases, allows the dilation procedure to be performed by a single operator. Additionally, the dilation catheter device and system may be useable in conjunction with an endoscope and/or a fluoroscope to provide for easy manipulation and positioning of the devices and real time visualization of the entire procedure or selected portions thereof. In some embodiments, an optional handle may be used to facilitate grasping or supporting a device of the present invention as well as another device (e.g., an endoscope) with a single hand.

Medical devices, systems and methods that are useable to facilitate transnasal insertion and positioning of guidewires and various other devices and instruments at desired locations within the ear, nose, throat, paranasal sinuses or cranium. Direct viewing of such placements via an endoscope.

A device, method and system for facilitating treatment of a sinusitis condition, including a heat source configured to deliver an output of heated air to the nasal passages of an individual, and a delivery component having a space through which the heated air output of the heat source may pass, the delivery component being configured for placement in the individual's nostrils. The system provides a heated air output source and one or more delivery components configured and sized to fit within the nostril of an individual, which may be used to deliver one or more courses of heated air to a user's sinuses through a nostril.

Systems, devices, and methods comprising an instrument for expanding a paranasal sinus. The instrument may comprise an expandable disposable medical device is adapted to extend away from a distal portion of a shaft of an insertion device.

Medical devices which are adapted to be inserted into a patient for a limited period of time using minimally invasive insertion procedures for dilating a stenotic opening, such as a stenotic sinus opening, are provided. The devices and methods can be used for treating sinusitis and other nasal and/or sinus disorders.

Medical devices which are adapted to be implanted into a patient for a limited period of time using minimally invasive insertion procedures for dilating a stenotic opening, such as a stenotic sinus opening, are provided. The devices and methods can be used for treating sinusitis and other nasal and/or sinus disorders.

A therapeutic aerosol device in which an aerosol generated by a nebulising device is supplied through a nosepiece to a patient's nostril so that the main aerosol flow supplied is able to emerge from the other nostril. The main aerosol flow is superimposed by pressure fluctuations. In order to guarantee that, due to the pressure fluctuation, aerosol is transported to the paranasal sinuses, a low resistance device is provided in the other nostril.

The present invention relates to a stent, adapted for deployment in a nasal sinus, comprising a matrix metalloproteinase-inhibiting substance and capable of locally releasing in a controlled manner a therapeutically effective amount of said matrix metalloproteinase-inhibiting substance. The invention further relates to a method for treatment of a diseased or damaged sinus mucosal tissue in a patient, said method comprising introducing into the sinus of said patient a stent comprising a matrix metalloproteinase-inhibiting substance.

The presence of a pathologic process in a lung of a mammal is detected by applying exhaled gas of a mammal to an electronic nose (12). Data derived from the electronic nose (12) is used to determine whether a pathologic process is present in the lung of the mammal. The pathologic process may also be a lung infection such as pneumonia. Also, a mammalian fluid sample obtained from the sinus or nose is applied to an electronic nose (12) to determine if the fluid sample contains significant amounts of cebrospinal fluid.

The present invention relates to a novel compound or a salt thereof, which is useful as a CRTH2 antagonist, especially as a medicament for disorder that participates eosinophil, for example, allergic disorder such as asthma, allergic rhinitis, allergic dermatitis, conjunctival inflammation, hives, eosinophilic bronchitis, food allergy, inflammation of the nasal sinuses, multiple sclerosis, angiitis, or chronic obstructive pulmonary disease (COPD) and the like.

The invention discloses a paranasal sinus holder and a special conveying appliance thereof, which belong to the technical field of paranasal sinus dilation equipment. The invention has the technical points that the paranasal sinus holder is a tubular body; the tube wall of the tubular body is of a netted structure made of an elastic material; the conveying appliance comprises a control handle; the side wall of the control handle is provided with a slot hole; a sliding handle is arranged in the slot hole; the free end of the sliding handle, which is located in the control handle, is connected with a flexible outer sleeve; the free end of the flexible outer sleeve extends to the outside of the control handle; a flexible inner tube is movably sheathed in the flexible outer sleeve; one end of the flexible inner tube passes through the control handle and is communicated with the outside; and the other end of the flexible inner tube is matched with the flexible outer sleeve to form a containing cavity used for containing the compressed paranasal sinus holder. The invention aims to provide the paranasal sinus holder with a simple structure and a good service effect and the special conveying appliance with a compact structure and simplicity and convenience in operation. The paranasal sinus holder and the special conveying appliance thereof are used for paranasal sinus dilation.

A set of sinus balloon catheters are provided for treating a patient's paranasal sinus system, including dilating prepared openings, and natural ostia and ducts and excising sinus cavities. These include a balloon catheter with a bend placing a distal segment at 90.degree. to a proximal segment and a balloon catheter which is substantially straight. The catheters have sufficient stiffness and column strength that the balloon carrying distal segment of the catheter can be pushed into the prepared opening, natural ostium or duct, or sinus to be excised. The catheters have appropriate inflated working diameters and appropriate outer diameters with the balloon deflated that will enable the catheter to be pushed into the respective prepared opening, natural ostium or duct, or sinus cavity to be excised. The methods use the balloon catheters to dilate prepared openings to selected parts of the sinus system, to dilate natural ostia and ducts of the sinus system, and/or to dilate sinus cavities to remove them.

Devices that are adapted to insert a sinus dilator into a stenotic opening of a paranasal sinus of a subject using minimally invasive dilator insertion procedures are provided. The devices and methods can be used to treat sinusitis and other nasal and/or sinus disorders.
