摘要:
Systems, apparatus, and methods are disclosed for gripping and/or positioning a plug (320) in an ear canal outside a tympanic membrane, performing iontophoresis, and/or delivering a pressure equalization tube to the tympanic membrane, including a rigid body (323), an electrode (352), and/or a liner strip (380). The rigid body may define a channel (321), a vent path (329), and a reservoir (370) in fluid communication with the channel the vent path. The reservoir may be configured to increase the volume of the channel, thereby tolerating volumetric changes in the ear without exposing the electrode disposed within the channel to air. The electrode may define a longitudinal axis from which the reservoir extends laterally and proximally to increase a spacing between the electrode and the vent path. The liner strip may include a plurality of gripping portions and attachment portions to cover at least some of a pressure sensitive adhesive on the plug.
