  • System and method for treatment of eustachian tube from middle ear approach
    Patent number: 11944518
    Abstract: 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.
