摘要： An apparatus comprises a shaft, an expandable dilator, and at least one ventilation pathway. The shaft defines a longitudinal axis and comprises a distal and proximal ends with at least one shaft lumen. The expandable dilator comprises body with its own proximal and distal ends. The body is configured to transition between a contracted state and an expanded state. The body is configured to dilate a Eustachian tube of a patient in the expanded state. The at least one ventilation pathway is configured to provide ventilation from the distal end of the body to the proximal end of the body when the body is in the expanded state. In some examples, the ventilation pathway comprises a set of transversely oriented vent openings formed through the shaft. In some other examples, the ventilation pathway comprises a space defined between one or more radially outwardly protruding features of the expandable dilator.

摘要： A dilation apparatus comprises an elongate member and a dilation assembly that is slidable along the elongate member. The dilation assembly comprises a platform and an inflatable dilator. The platform and the elongate member cooperate to absorb inflation forces from the dilator directed toward the longitudinal axis of the elongate member, such that the dilation forces are exerted against tissue asymmetrically relative to the longitudinal axis of the elongate member. The dilation apparatus may be used to dilate the ethmoid infundibulum in a human patient. Various devices may be used to maintain the dilated state of an ethmoid infundibulum, including a wedge, a mesh, and a tether. An illuminator may be configured to reach around an uncinate process, retract the uncinate process, and then illuminate the ethmoid infundibulum to provide improved visualization of the ethmoid infundibulum.

摘要： Devices and methods for dilating the ostia of paranasal sinuses and other passageways within the ear, nose and throat. A mechanical dilator is inserted through a nostril and used to dilate an ostium or a paranasal sinus or other passageway within the ear, nose or throat (e.g., a Eustachian tube or nasolacrimal duct). The mechanical dilator may be an expandable dilators that comprises one or more non-balloon structures with or without an accompanying balloon or a members of varying diameter or cross dimension (e.g., a tapered member) that may be advanced into the ostium or other passageway to cause dilation of that passageway.
