Claim 13:
14. A dilation catheter, comprising:
(a) a rigid proximal body, the rigid proximal body comprising:
(i) an inflation port, and
(ii) an elongate portion extending distally from the inflation port along a longitudinal axis, the elongate portion defining a first section of an inflation lumen, the first section of the inflation lumen being in fluid communication with the inflation port;

(b) an inflatable balloon configurated to transition between a deflated state and an inflated state; and
(c) a distal shaft extending distally from the elongate portion of the rigid proximal body, the distal shaft being coupled with the inflatable balloon, the distal shaft defining a second section of the inflation lumen, the second section of the inflation lumen being in fluid communication with the first section of the inflation lumen and the inflatable balloon, the distal shaft being configured to transition from an initial angle relative to the longitudinal axis to a selected angle relative to the longitudinal axis, the distal shaft being configured to access a targeted anatomical passageway of a patient without buckling in the selected angle,
the inflatable balloon and the distal shaft being dimensioned to access a Eustachian Tube of a patient via a pre-tympanic approach and a myringotomy approach.
