SEMI-PERMANENT CANAL HEARING DEVICE

摘要

A semi-permanent hearing device is disclosed which is adapted to be complete ly positioned within the ear canal of an individual for long-term use. The devi ce comprises a sealing retainer (70) substantially positioned in the bony regio n of the ear canal and a core assembly (35) including a receiver assembly (60) coaxially positioned within the sealing retainer. When the device is inserte d into its completely-in-the-canal position, the core assembly (35) extends fr om the sealing retainer (70) to the cartilaginous region of the ear canal in a non-occluding fashion, thereby minimizing interference with hair and earwax production present in the cartilaginous region. In a preferred embodiment of the device, the core assembly comprises a battery assembly (50) conforming substantially to the shape and dimensions of the battery enclosed within the assembly. A connector (53) in the form of a thin ribbon film provides electrical and flexible mechanical connectivity between the receiver assembl y (60), the centrally positioned battery assembly (50), and a microphone assembly (40) positioned in the cartilaginous region.
