Publication number: 20230123143Abstract: A tympanostomy tube placement device has a stem with a needle having a tip configured to pierce a tympanic membrane. A retainer is on the needle and includes four fingers extending axially at a distance from said axis and at 90° circumferential separations in one example. The retainer is movable from a distal position at which it presses radially inwardly against the tube distal flange tabs to retain the distal flange in a folded position, to a proximal position at which the tube distal flange is free to spring out radially to a deployed position. The retainer fingers extend through tube proximal flange passageways and press the tube distal flange inwardly, while leaving a distally-facing face of the proximal flange exposed radially outwardly of the retainer. Hence, the proximal flange has its final deployed configuration throughout, and so can act as a physical stop member against the tympanic membrane and also provides visualisation for the surgeon because it extends radially outwardly of the stem.Type: ApplicationFiled: November 30, 2022Publication date: April 20, 2023Applicant: AVENTAMED DESIGNATED ACTIVITY COMPANYInventors: John VAUGHAN, Olive O'DRISCOLL, Carol GRIMES

Publication number: 20230110173Abstract: 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.Type: ApplicationFiled: November 29, 2022Publication date: April 13, 2023Applicant: AVENTAMED DESIGNATED ACTIVITY COMPANYInventors: John VAUGHAN, Olive O'DRISCOLL, Carol GRIMES
