Abstract
The device comprises a core, surrounded by a thin sheath so as to form a chamber that can be inflated. Inflation is done while the device is inside the ear, using an inflation tool. The tool injects a solid-setting fluid into the chamber. After curing, the tool is detached, leaving a finished in-ear unit, upon which no further manufacturing processing is required.
