Devices and methods for insertion and/or pressurization of a balloon catheter for balloon dilation of the eustachian tube and other anatomical passageways accessible through the nostril of a human

A handheld insertion device for balloon dilation of the Eustachian tube or any other anatomic passageway in the head of a person, the device comprising:

• a balloon catheter,
• a syringe assembly comprising several parts, the several parts comprising a syringe barrel, a sealing element and a plunger rod,
• a balloon catheter guiding tube for receiving and guiding the balloon catheter,
• a device body rigidly attached to a proximal end of the balloon catheter guiding tube,
• the balloon catheter having a distal inflatable part to be advanced out from the distal end of the balloon catheter guiding tube and a proximal part being fluidically connectable to the syringe assembly for inflation and pressurization of the balloon catheter,
• wherein the device body comprises guiding means for movement of one or more parts of the syringe assembly towards the balloon catheter guiding tube, and wherein
• the balloon catheter is operably coupled to one or more parts of the syringe assembly for advancing the balloon catheter out from the distal end of the balloon catheter guiding tube by linear motion of the one or more parts of the syringe assembly,
• wherein:
• the guiding means for movement of one or more parts of the syringe assembly towards the balloon catheter guiding tube comprises guiding means for movement of the entire syringe assembly towards the balloon catheter guiding tube.
