Patent ID: 8605927

Claim:
A hearing aid comprising: a hearing aid shell with hearing aid electronics disposed therein, the hearing aid electronics including a power source, a microphone, a signal processor and a receiver, the receiver projecting a hearing aid amplified audio output out of a sound output port on a distal side of the hearing aid shell; and a flexible filament extending out of a proximal side of the hearing aid shell, the flexible filament extending outside the profile of the hearing aid shell, such that the filament interacts with a user's ear anatomy to determine an insertion depth of the hearing aid shell into the user's ear canal by preventing the hearing aid from being pushed too deep into the ear canal by the user, the flexible filament being shape retaining, wherein the flexible filament comprises an ear canal reverse loop for making contact against the skin of the bottom of the ear canal to help raise the hearing aid in the ear canal, the ear canal reverse loop extending distally in a direction toward the distal side of the hearing aid shell and then looping to extend proximally off the hearing aid shell.
