Systems and methods of tympanostomy tube delivery

A tube delivery system for installing a tympanostomy tube, the tube delivery system comprising:

• a hand piece;
• a shaft assembly extending distally from the hand piece, the shaft assembly comprising:
• an elongate outer tube;
• an introducer defining a distal end, a first leaf on the distal end, a second leaf on the distal end, and an inside diameter, the introducer concentrically disposed within the elongate outer tube;
• the tympanostomy tube, wherein the tympanostomy tube is disposed within and directly abuts the inside diameter of the introducer;
• and
• a pusher concentrically disposed within the introducer;
• and
• a drive assembly disposed within the hand piece, the drive assembly configured to longitudinally translate the introducer and the pusher relative to the elongate outer tube, wherein the drive assembly is configured to dilate the first leaf and the second leaf by the pusher distally translating the tympanostomy tube relative to the introducer such that the tympanostomy tube directly contacts and dilates the first leaf and the second leaf to facilitate installation of the tympanostomy tube.
