Abstract: The present disclosure provides a device (30) for delivering a substance to the inner ear. The device (30) comprises a pressure oscillator (32) configured to generate pressurised air at a predetermined oscillation frequency, an aural probe (31) comprising an air passageway extending from a first end of the aural probe (31) to a second end of the aural probe (31), the first end being the end to be inserted into the ear canal, a tube (33) arranged to couple the second end of the aural probe (31) to the pressure oscillator (32), and a pressure relief valve (34) disposed at the tube (33) and/or the aural probe (31) configured to release a portion or the generated pressurised air from within the tube (33) and/or the aural probe (31) when a pressure within the tube (33) and/or the aural probe (31) reaches a predetermined maximum pressure. The present disclosure further provides a method for delivering a substance to the inner ear, the method comprising the steps of: (i) administering the substance to the middle ear; and (ii) generating oscillating air pressure within the ear canal.
