摘要： A dilation catheter system comprises a guide member, a dilation catheter, and an image sensor. The guide member includes a shaft comprising a distal end and a proximal end. The shaft further defines a longitudinal axis. The dilation catheter is movable relative to the guide catheter member and comprises an expandable dilator. The expandable dilator is sized to fit within one or both of a Eustachian tube or a passageway associated with a paranasal sinus. The image sensor is configured to provide visualization within anatomy of a patient. The image sensor is integral with the guide member.

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 system includes a balloon catheter and a puncturing assembly. The balloon catheter includes a shaft, a dilator coupled to a distal end of the shaft, and a lumen extending through the shaft and the dilator. The dilator is expandable from a collapsed state to an expanded state. The puncturing assembly includes at least one cutting member. The puncturing assembly is positionable within the lumen of the balloon catheter or along an exterior of the shaft when the puncturing assembly is in a first position. The puncturing assembly transitions to a second position to puncture the lumen of the balloon catheter and/or to puncture the dilator, to thereby drain fluid from the dilator.

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 system for delivering a fluid to a Eustachian tube (ET) of a patient includes a guide member and a tubular member. The guide member includes a shaft having a proximal portion, a distal portion, and a bend at the distal portion. The bend is configured to provide access to an opening in the ET. The system further includes a tubular member comprising a proximal end, a distal end, and a lumen extending therebetween. The tubular member is sized to fit within the ET. One or both of the tubular member and the guide member comprises a first stop member configured to engage the other of the tubular member or the guide member. The first stop member is configured to restrict a distal advancement of the tubular member relative to the guide member.
