Abstract
A device for repairing a tympanic membrane comprises a patch provided on one side with an adhesive layer, and an elongate tubular applicator member having a proximal end and a distal end. The patch is removably attached via suction to the distal end of the tubular applicator member so that the adhesive layer faces away from the elongate applicator member. The proximal end of the tubular applicator member is temporarily closed or sealed to maintain the suction force, thereby holding the tympanic patch to the distal end of the applicator tube while the tube is being inserted through the auditory canal. Upon a pressing of the patch against the ear drum so that the patch covers the perforation, the proximal end of the tube is released to pressurize the tube channel with ambient air. This pressurization releases the patch and allows it to adhere to the tympanic membrane.
