An end effector for a surgical stapler. Various embodiments include a channel configured to operably support a staple cartridge therein. A first tip portion is attached to or formed on a distal end of one of the channel and staple cartridge wherein the first tip portion may have a first upwardly extending curved outer surface. An anvil is movably coupled to the channel and is selectively movable between open and closed positions relative to the staple cartridge in response to opening and closing motions applied to the anvil. A second tip portion is attached to or formed on a distal end thereof. The second tip portion may have a second downwardly extending curved surface such that when the anvil is in the closed position, the second tip portion cooperates with the first tip portion to define a blunt end effector nose. In various embodiments, the end effector nose has a substantially paraboloid outer surface.

A method is disclosed for treating benign conditions, such as enlarged tonsils and / or adenoids located in a patient's throat or nasopharynx, or soft tissue lesions located in a patient's oropharynx or larynx. According to the method, a space containing the patient's nasopharynx, oropharynx or pharynx and larynx is isolated from the patient's trachea and lungs using an inflatable cuff tracheostomy tube or nasotracheal tube inserted in the patient's trachea. The cuff is inflated to occlude the trachea. The patient is placed in a supine position, whereupon at least a portion of the space containing the nasopharynx and / or oropharynx and larynx is filled with saline. An endoscope is then inserted into the space to view the operative site in which the tonsils or tissue lesion are to be treated. An electrosurgical instrument having an active tissue treatment electrode and a return electrode connected to an electrosurgical generator is then inserted into the space, either along side the endoscope or through the endoscope's working channel. The generator is then operated to apply a radio frequency voltage between the active and return electrodes of the electrosurgical instrument, whereby a conduction path is formed between the active and return electrodes, at least partially through the saline, whereupon the active electrode is manipulated to debulk or otherwise treat the soft tissue lesion or enlarged tonsils and / or adenoids.

Devices, systems and methods for performing image guided interventional and surgical procedures, including various procedures to treat sinusitis and other disorders of the paranasal sinuses, ears, nose or throat.

An apparatus for insufflating a treating gas into a patient and for measuring a carbon dioxide content exhaled by the patient includes a hollow body with a partitioning wall separating the body into inhalation and exhalation manifolds. Two hollow prongs have coaxial openings close to the body which allow gas exchange for breathing and carbon dioxide measuring purposes. The holes are of a size such that suction drawn through the holes is limited while still allowing accurate gas analysis.

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.

A patient interface that reliably and comfortably seals a user's face by providing an oral-nasal mask that includes an integrated nasal interface. The patient interface includes a seal member having an oral cushion portion configured to surround the user's mouth and a nasal interface portion that provides an interface with the user's nose. The seal member, including the oral cushion portion and the nasal interface portion, is a unitary member. Finally, the nasal interface portion remains below the bridge of the nose.

Headwear is adapted for use by a patient to position airway tubes of a nasal interface operatively connected to a positive airway pressure device. The headwear includes an elongated head strap for being worn around a head of the patient. Cooperating sets of front and rear tube holders are attached to the head strap, and are adapted for engaging and holding respective airway tubes of the nasal interface to retain the tubes in a desired position during use. The tube holders include at least one elastic strip extending along a longitudinal dimension of the head strap.

The ventilation interface for sleep apnea therapy interfaces a ventilation device to the patient's airways. The ventilation interface includes a pair of nasal inserts made from flexible, resilient silicone which are oval shaped in cross-section and slightly tapered from a base proximal the ventilation supply to the distal tip end. A bead flange is disposed about the exterior of each insert at the distal end of the insert. In one embodiment, a valve is disposed between the nasal inserts and a source of positive airway pressure, the valve having a rim with a one-way diaphragm pivotally attached to the valve body with an inflatable bladder depending from the rim which seals against an exit port during inspiration and deflates to uncover the exit port on expiration. Another embodiment has nasal inserts without positive airway pressure but with a removable filter in the inserts for filtering inspired air.

Devices, systems and methods for stenting, spacing, draining, ventilating and / or delivering drugs and other therapeutic or diagnostic substances to desired locations within the bodies of human or non-human animal subjects, including methods and systems for treating paranasal sinusitis and ethmoid disease.

Sinusitis and other disorders of the ear, nose and throat are diagnosed and / or treated using minimally invasive approaches with flexible or rigid instruments. Various methods and devices are used for remodeling or changing the shape, size or configuration of a sinus ostium or duct or other anatomical structure in the ear, nose or throat; implanting a device, cells or tissues; removing matter from the ear, nose or throat; delivering diagnostic or therapeutic substances or performing other diagnostic or therapeutic procedures. Introducing devices (e.g., guide catheters, tubes, guidewires, elongate probes, other elongate members) may be used to facilitate insertion of working devices (e.g. catheters e.g. balloon catheters, guidewires, tissue cutting or remodeling devices, devices for implanting elements like stents, electrosurgical devices, energy emitting devices, devices for delivering diagnostic or therapeutic agents, substance delivery implants, scopes etc.) into the paranasal sinuses or other structures in the ear, nose or throat. Specific devices (e.g., tubular guides, guidewires, balloon catheters, tubular sheaths) are provided as are methods for manufacturing and using such devices to treat disorders of the ear, nose or throat.
