An apparatus for delivering an agent to an inner ear of a subject characterized by: a reservoir (30, 630) comprising an exterior wall (42, 642) and an internal cavity (38, 638) therein surrounded by the wall (42, 642); an elongate and tubular primary stem portion (14, 614) comprising an open first end (20, 620), a second end (22, 622), and a passageway (24, 624) extending continuously through the primary stem portion (14, 614), the second end (22, 622) of the primary stem portion (14, 614) being connected to the reservoir so that the passageway through the primary stem portion is in fluid communication with the internal cavity of reservoir (30, 630); and a fluid transfer means (43, 643) within the wall (42, 642) of the reservoir (30, 630) for enabling passage of fluid materials through the wall (42, 642). |
