Abstract
A removal tool for removing canal hearing devices from the ear canal, examples of which may include a hand piece and a removal loop having a wide section for placing over a knob handle structure incorporated within the canal hearing device, and a narrow section for interlocking with the knob handle to remove the hearing device from the ear. The removal loop is generally configured in the shape of keyhole to guide and transition of the knob and shaft of the knob handle into the narrow section for capture and interlocking therewithin. The removal tool may provide ease of use, particularly for individuals with poor dexterity and/or poor vision. In a preferred embodiment, the removal loop is made of a single formed wire for improved durability, lower cost of fabrication, and safe operation that minimizes contact with the walls of the ear canal.
