Problems solved by technology

Therefore, these patients have severe conductive hearing loss
One problem associated with an ossified oval window membrane 201 is that the stapes floor cannot transmit incoming acoustic sounds in the form of pressure waves into the fluid within the cochlea 200
However, opening and maintaining a permanent hole in the stapes floor is dangerous because of the increased risk of infection

Embodiment Construction

[0022] Various embodiments of the present invention relate to a middle ear implant (MEI) that provides significant hearing improvement to patients with otosclerosis with an ossified oval window membrane. Figure 4-B shows a functional representation of a human cochlea 200 having an ossified oval window membrane 401 with an 402 engages an offset mechanical transducer 404 . A mechanical transducer 404 such as a floating mass transducer (FMT) is surgically implanted at an angle in a fixed position in the round window niche 403 of the patient's cochlea 200 adjacent to the round window membrane 402 .

[0023] The drive face 406 on the outer surface of the transducer 404 has a diameter that is less than half the diameter of the round window membrane 402 . The drive face 406 may, for example, be a flat surface or a surface of spherical cross-section (eg, a spherical tip as in Lupo). The fixed position of the transducer 404 engages the drive surface 406 relative to the side section o...

Abstract

A middle ear transducer arrangement is described for engaging a round window membrane of a patient cochlea. A mechanical transducer is surgically implantable into a fixed position in the round window niche of the patient cochlea adjacent to the round window membrane. A drive face on the outer surface of the transducer has a diameter less than half the diameter of the round window membrane. The fixed position of the transducer engages the drive face against a side section of the round window membrane without engaging the center point to generate an acoustic stimulation signal for perception as sound.

Description

[0001] This application claims priority to US Provisional Patent Application 61 / 447,273, filed February 28, 2011, which is hereby incorporated by reference. technical field [0002] The present invention relates to hearing implants, and in particular to transducers for patients suffering from otosclerosis. Background technique [0003] Such as figure 1 As shown in , the normal ear transmits sound through the outer ear 101 to the tympanic membrane (eardrum) 102, which moves the ossicles of the middle ear 103 (malleus, incus, and stapes), which vibrate the cochlea 104 oval window and round window membranes. The cochlea 104 is a long, narrow organ that spirals about two and a half turns around its axis. It consists of an upper passage called the vestibule and a lower passage called the scala tympani, which are connected by the cochlear duct. The cochlea 104 forms an upright spiral cone, the center of which is called the modiolus, in which the spiral ganglion cells of the aud...
