Abstract: A tympanoplatic patch applicator comprising: a handle disposed with a deployment control; a deployment stem comprising multiple nested sleeves connected to the handle; a patch configured to be affixed to the distal end of the deployment stem via an actuation filament embedded in the deployment stem; and a filament-based deployment system controllable by the deployment control, wherein the deployment stem is configured to position the patch at the internal side of a perforated tympanic membrane in the middle ear by introducing the patch into the ear canal and penetrating the perforated tympanic membrane with the distal end of the deployment stem, and wherein the filament-based deployment system is configured to release the patch from the distal end of the deployment stem, thereby deploying the patch on the internal side of the perforated tympanic membrane.
