Problems solved by technology

For example, known support structures used to hold magnets in place during the healing process (such as GELFOAM TM ) may become dislodged and allow the magnet to move; tissue growth may occur unevenly between the magnet and the ossicles, thus altering the initial position of the magnet; and intense physical activity may dislodge the tissue before it completely encapsulates the magnet

Embodiment Construction

[0047] exist figure 1 The human ear is represented in . It includes the outer ear 2 , the middle ear 4 and the inner ear 6 . Relevant to the description of the invention is the external auditory canal 8 which is normally closed at its inner end by the tympanic membrane or eardrum 10 . Also relevant is the chain of ossicles which, if intact, extend from the eardrum 10 to the oval window 12 which defines the entrance to the inner ear 6 . A complete chain of ossicles extends through the middle ear 4 and includes the malleus 14 , incus 16 and stapes 18 . A properly functioning ossicle chain transmits vibrations from the eardrum 10 to the oval window 12 in series through the malleus 14 , incus 16 and stapes 18 . The vibrations at the oval window stimulate the inner ear 6 , whereby the person perceives the sound received in the outer ear 2 .

[0048] It is an object of the present invention to provide vibration stimulation to the inner ear 6 when there is otherwise insufficient ...

Abstract

An improved middle ear implant and method are disclosed. The invention particularly relates to magnetic implants and to attachment devices and methods for mounting a magnet in the middle ear of a patient. The implant comprises a wire-form and a magnet disposed in a housing. The method may comprise the steps of: positioning a magnet in optimal alignment; and attaching said magnet to an ossicle in the middle ear. The method may further comprise the step of using a wire-form to attach the implant to the ossicle. Still further, the method may comprise the step of anchoring the implant to the ossicle with biological cement.

Description

technical field [0001] The present invention relates generally to the field of middle ear implants and improvements in obtaining sound quality for middle ear implant patients. The present invention more particularly relates to an improved device and method for use in or with a magnetic middle ear hearing system. The present invention most particularly relates to improved magnetic implants and improved attachment devices and methods for installing magnets in a patient's middle ear. Background technique [0002] There are many different reasons why some people have hearing loss. In general, however, sound entering the external auditory canal is not transmitted to the inner ear and / or to the auditory nerve. In some instances, this can be resolved by amplifying the sound with a hearing aid placed in the external ear canal. In other cases, cochlear implant devices that electrically stimulate the auditory nerve are placed directly in the cochlea of ​​the inner ear. In still ot...
