Eustachian tube dilator systems

Abstract

Some implementations of the disclosure are directed to a eustachian tube dilator system including: a housing for removably inserting an endoscope, the housing including an insert ratchet mechanism or top down ratchet mechanism configured to couple to a proximal rigid end of the endoscope; and a hollow balloon cannula coupled to and distally extending from the housing, the hollow balloon cannula including a curved distal end configured to couple to a flexible distal end of the endoscope, and the hollow balloon cannula configured for insertion of a balloon catheter used for eustachian tube dilation such that a distal balloon of the balloon catheter is advanced through the hollow balloon cannula from a proximal opening of the hollow balloon cannula to a distal opening of the hollow balloon cannula.

Dependencies are inferred from the claim text.
