Problems solved by technology

Conductive hearing loss occurs when the normal mechanical pathways that provide sound to hair cells in the cochlea are impeded, for example, by damage to the ossicular chain or ear canal.

Embodiment Construction

[0033]According to an exemplary embodiment, there is an implant comprising a substantially flat base with a circular periphery and a sidewall extending orthogonally therefrom. The combination of the base and the sidewall form a compartment with an opening opposite the base. The implant is configured for implantation into a recess formed in a recipient's skull and securement thereto via osseointegration. The implant is configured to removably receive in the compartment a separate implantable component, such as a module containing a vibrating actuator of a transcutaneous bone conduction device, such that the separate implantable component is removable from the implant without detaching the housing from the skull.

[0034]According to another exemplary embodiment, there is an implantable medical device including an implant which contains a functional component of the implantable medical device, such as a vibrating actuator of a transcutaneous bone conduction device. The implant comprises ...

Abstract

An implant configured for secured implantation into a recess formed in a recipient's bone and to removably retain a separate component in a compartment thereof such that the separate component is removable from the implant without removing the implant from the bone.

Description

BACKGROUND[0001]1. Field of the Invention[0002]The present invention relates generally to implantable medical devices.[0003]2. Related Art[0004]Hearing loss, which may be due to many different causes, is generally of two types: conductive and sensorineural. Sensorineural hearing loss is due to the absence or destruction of the hair cells in the cochlea that transduce sound signals into nerve impulses. Various hearing prostheses are commercially available to provide individuals suffering from sensorineural hearing loss with the ability to perceive sound. For example, cochlear implants use an electrode array implanted in the cochlea of a recipient to bypass the mechanisms of the ear. More specifically, an electrical stimulus is provided via the electrode array to the auditory nerve, thereby causing a hearing percept.[0005]Conductive hearing loss occurs when the normal mechanical pathways that provide sound to hair cells in the cochlea are impeded, for example, by damage to the ossicul...
