Abstract: Devices and methods for extracochlear stimulation are described herein. Such devices and methods may be configured for improving hearing in a subject in need thereof in any frequency range. In some embodiments, high frequency ranges are particularly targeted by the energy delivery elements provided herein. Low frequency ranges may be amplified by an acoustic amplifier, in various embodiments. Further, an external surface of the cochlea may be minimally prepared or altered prior to or during electrode placement on the cochlear surface. Such minimal preparation may include: disrupting mucosa on the external surface of the cochlea, applying an acid to the external surface of the cochlea, or applying a tissue growth factor to the external surface of the cochlea.

Abstract: A display unit for displaying sheet materials includes a channel support member and a plurality of channel members connected to the channel support member. Each of the channel members includes a pair of channel arms defining a channel shape. The channel arms extend outward from the base point and converge at a contact point disposed between a base point and distal ends of the channel arms. The channel arms preferably diverge beyond the contact point such that the distal ends are flared. Preferably, the channel members are formed integral with the channel support member by being extruded or cast from a plastic or other material. The display unit has a simple construction and is thus easy and inexpensive to manufacture. The display unit can be used laying flat, standing vertically, or hanging. The display unit can display multiple items and the items can be of various sizes, shapes and orientations.
