    摘要: An inflator system comprises a dilation catheter and a fluid pressure regulator assembly. The dilation catheter comprises a shaft defining a lumen and being sized to fit within an anatomical passageway. The dilation catheter further comprises a dilator configured to receive fluid through the lumen and thereby expand in response to fluid communicated through the lumen. The fluid pressure regulator assembly comprises a pump in fluid communication with the dilation catheter. The fluid pressure regulator assembly further comprises a control module configured to store one or more fluid pressure profiles and is operable to receive a selection of a particular fluid pressure profile from the one or more of fluid pressure profiles. The control module is operable to selectively drive the pump in accordance with a selected fluid pressure profile. The fluid pressure regulator assembly further comprises a user input feature operable to selectively activate the control module.

    摘要: An apparatus comprises a shaft, an expandable dilator (1850), and at least one ventilation pathway (1855). The shaft defines a longitudinal axis and comprises a distal and proximal ends with at least one shaft lumen (1853). The expandable dilator comprises body with its own proximal and distal ends (1856, 1851). 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.
