摘要： Systems and methods for treating target tissues within the ears are disclosed. Systems include a device including a cutting edge configured to form an incision in a tympanic membrane, a pressure equalization tube positionable within an interior space of the device in a compressed configuration and configured to expand into an expanded configuration when released from the interior space, and an elongate positioning element configured to release the pressure equalization tube from the interior space such that the pressure equalization tube is deployed in the incision formed in the tympanic membrane.

摘要： A myringotomy device includes a housing; an elongated tube extending from the housing; and a retractable cutting tool extendable through the elongated tube, the cutting tool comprising a blade. The cutting tool is configured such that when advanced, the blade of the cutting tool extends beyond a distal end of the elongated tube. The cutting tool is also configured such that when retracted, the blade is retracted into the elongated tube and a fluid conduit is created from the distal end of the elongated tube to the housing.

摘要： An apparatus and method is provided for reducing middle ear fluid and equalizing middle ear pressure in infants and toddlers. The apparatus coordinates the act of swallowing and the forcing of air into the nostril of the child. The coordinated actions allow air forced into the nostril to traverse the Eustachian tube when in its open state. A flexible member and a main flexible tube, connected accordingly, are both adapted to be inserted into the child's mouth and nostril, respectively, to achieve such coordination and allow air to enter the Eustachian tube when in its open state, ultimately allowing air to reach the middle ear.

摘要： A tympanostomy tube delivery device comprises a shaft assembly, a pressure equalization tube, and a trigger assembly. The shaft assembly comprises a cannula and a pusher operable to translate relative to the cannula. The pressure equalization tube is positioned within the shaft assembly. The pusher is operable to drive the pressure equalization tube out of the shaft assembly. The trigger assembly includes a pair of pushbuttons and a linkage. The pushbuttons are secured to the device via living hinges and are selectively pivotable. The linkage is configured to engage the delivery device to thereby selectively prevent actuation of the delivery device. The pivoting of one or both the pushbuttons is configured cause the linkage to collapse so as to disengage the delivery device and thereby actuate the delivery device.

摘要： A method is disclosed for clearing effusion from an ear. The method may include applying liquid to an ear canal, which is proximal to a perforated tympanic membrane, which is proximal to a middle ear containing effusion, applying an ear device to seal and pressurize the liquid inside the ear canal, the ear device regulating the amount of pressure inside the ear canal, and inducing a Eustachian tube, which is distal to the middle ear, to open, which causes the fluid to displace the effusion into the Eustachian tube.

摘要： A dilation catheter includes a shaft and an expandable element. The shaft includes a proximal portion and a distal portion. The distal portion includes a tip and a bend. The tip is sized and configured to pass through an isthmus of a Eustachian tube (ET). The bend is proximal to the tip. The bend is formed at an angle configured to provide insertion of the tip into the isthmus of the ET via an ear canal associated with the ET. The expandable element is disposed at the distal portion of the shaft. The expandable element is configured to transition between a non-expanded state and an expanded state. The expandable element in the non-expanded state is configured for insertion into the ET via the isthmus. The expandable element in the expanded state is configured to dilate the ET.

摘要： A method of dilating a first Eustachian tube (ET) and a second ET of a patient using a dilation catheter includes directing the dilation catheter into the mouth of the patient and advancing the dilation catheter into a first ET on one side of the patient's head while a proximal portion of the dilation catheter is disposed in the mouth of the patient. The method further includes expanding the expandable member to thereby dilate the first ET. The method may further include repositioning the dilation catheter relative to a second ET on another side of the patient's head and advancing the dilation catheter into the second ET while a proximal portion of the dilation catheter is disposed in the mouth of the patient. The method may further include expanding the expandable member to thereby dilate the second ET.

摘要： A system and method for dilating a Eustachian tube of a patient is disclosed. The device includes a protective sheath, a flexible endoscope and a balloon dilation catheter. The protective sheath includes an endoscope lumen and a balloon dilation catheter lumen. The balloon of the balloon dilation catheter is a low profile balloon particularly useful for dilating the Eustachian tube, and in particular, the Eustachian tube of a pediatric patient. The method involves advancing the balloon dilation catheter through a nasal passage of the patient to dilate a portion of the Eustachian tube.
