Abstract
An expandable in-ear device being implantable within an ear canal of an individual and being customizable in-situ to the shape of the ear canal, and cavum concha, using a settable compound. The device includes a core-form with a nipple extending from a platform, the nipple and the platform being insertable into the ear canal and the cavum concha, respectively. A sound bore extends through the nipple from a position located outside the ear canal to a position located inside for allowing sound transmission therethrough. A deformable sheath attached integrally to the core-form is deformable between an unfolded configuration and a folded configuration. In the unfolded configuration, the sheath extends generally away from the core-form. The sheath is foldable inside-out from the unfolded configuration to the folded configuration wherein the sheet substantially covers the core-form while defining a spacing between the sheath and the core-form, the spacing being fillable by the settable compound.
