Endovascular balloon dilation system. A Endovascular balloon and pressure gauge. B Suction tips used for eustachian tube dilation. From left to right—suction tip with a 45° angled tip, suction tip with a 70° angled tip, “s” shaped malleable suction tip. C Balloon length marking along the distal end of endovascular balloon catheter. The EVB catheter was marked at its distal end (beyond the suction tip) to gauge the balloon length distance at which the entire balloon would be inserted into the eustachian tube
