Abstract
A tympanostomy tube placement device has a needle with a tip, and a retainer at the needle tip. The retainer is within and retains by pulling radially inwardly a tympanostomy tube distal flange in a folded configuration extending distally. Movement of the needle tip in the proximal direction causes the adhesive bond to break and the distal flange releases to an unconstrained deployed position. Due to the axial folding of the distal flange its radial dimension does not affect deployment through the membrane.
