Hearing prosthesis utilizing external and implantable magnets
A recently granted patent (Publication Number: US11918808B2) discloses a hearing prosthesis that includes an external device with a magnet and an implantable device with a disk magnet. The implantable device is designed to allow the disk magnet to revolve in one plane and rotate in another, utilizing the magnets to retain the external device on the recipient of the hearing prosthesis. The disk magnet's movement is limited by the interior walls of a container, ensuring controlled rotation and unlimited revolving within the device.
Furthermore, the hearing prosthesis features additional components such as a stimulator unit, an electrode assembly with an array of electrodes, a sound processor, and a microphone. The implantable device includes a wire antenna coil, and the external device also includes a wire antenna coil, enhancing the functionality of the prosthesis. The design of the second magnet in the implantable device allows for specific movements, such as revolving around a longitudinal axis and rotating partially around another axis, ensuring optimal performance when implanted in a recipient. The patent details various configurations and limitations of the magnet apparatus within the hearing prosthesis, highlighting the innovative design and functionality of the device for individuals with hearing impairments.
