An implantable medical device, including a magnet and a body encompassing the magnet, wherein the implantable medical device includes structural components in the body configured to move away from one another upon initial rotation of the magnet relative to the body when the magnet is subjected to an externally generated magnetic field, thereby limiting rotation of the magnet beyond the initial rotation.

Magnet management MRI compatibility

An external portion of an auditory prosthesis includes an external magnet that interacts with an implantable magnet to hold the external portion against the skin. Magnetic force generated by the stray field of these magnets can disturb the operation of a vibrating element of the auditory prosthesis. The technologies described herein utilize additional magnets disposed within portions of the auditory prosthesis to redirect the magnetic flux, which allows the vibrating element to be disposed more closely to the magnets, reducing the overall height profile of the prosthesis.

Retention magnet system for medical device

Presented herein are magnet arrangements for use with encapsulated implantable components. An implantable component comprises an implant body and a plurality of wire loops forming an internal coil that are encapsulated in a biocompatible overmolding. The implantable component also comprises a bone fixture positioned proximate to the plurality of wire loops and an implantable magnet attached to the bone fixture.

Implantable magnet arrangements

A device, including a housing of a medical device configured to be implanted in a human recipient, the housing having at least one opening on one side of the housing, and a linear feedthrough assembly, wherein the linear feedthrough assembly closes the opening, the housing has a length, a width, and a height, wherein the height is the smallest dimension, and the opening is located in at least about the center of at least one of the length or the width, and the opening faces a direction normal to a plane established by the length and the width.

Feedthrough placement

An electric hearing prosthesis, wherein the electric hearing prosthesis includes an implantable portion configured to electrically stimulate a cochlea to evoke a hearing percept, and an external portion configured to be in wired communication with the implantable portion, wherein the electronic components of the implantable portion are all passive electronic components.

Implantable stimulating assembly with limited components

An apparatus, including a sterilely sealed package, and an electrode assembly sterilely sealed in the package, wherein the apparatus is configured to enable testing for an open circuit between two electrodes of the electrode assembly with the electrode assembly sterilely sealed in the package.

Electrode array packaging system

A magnetic alignment system that can form part of a cochlear implant system. The magnetic alignment system prevents substantial movement of a magnet of an implanted component during an MRI procedure or allows for easy removal of the magnet to facilitate the MRI procedure.

Implant magnet system

Presented herein are distributed implantable hearing systems that have at least a main implant module that is physically separated from a distally positioned inner radio-frequency (RF) coil. Embodiments presented herein may include a main implant module positioned within a recipient's mastoid and an implantable coil positioned within a recipient's middle ear cavity.

Distributed implantable hearing systems

An apparatus, including an external component of a medical device configured to generate a magnetic flux that removably retains, via a resulting magnetic retention force, the external component to a recipient thereof, wherein the external component is configured to enable the adjustment of the generated magnetic flux so as to vary the resulting magnetic retention force.

Magnetic retention device

An implantable prosthesis, including an implantable component including an implantable magnet assembly, wherein the magnet assembly includes a magnet plated with a metallic substance, the magnet assembly includes a housing made at least in part of a polymer, wherein at least a portion of the housing made out of the polymer is in direct contact with the metallic substance, and the implantable component is configured to be implanted in a human such that the housing is exposed to body fluids thereof.
