Moving Coil Actuator For Middle Ear Implants

A hearing enhancement includes an audio processor that generates an electrical audio signal and transmits the signal to a coil. The coil is implanted into a patient in a position that results in transmission of mechanical stimulation to the inner ear when the coil is spatially displaced. A permanent magnet is placed in proximity to the coil so that when the coil receives the electrical audio signal form the processor, the induced coil magnetic field in the coil interacts with the magnetic field from the permanent magnet to spatially displace the coil and, as a result, transmit the mechanical stimulation to the inner ear.

Low power signal transmission

ActiveUS20050283207A1Eliminating low-frequency spectral componentComponent can be removedHead electrodesEar treatmentUltra-widebandAudio power amplifier
A low-power implant system. The system includes an implant for implantation into a person, such as a cochlear implant or a middle ear implant. The implant is capable of communicating with a device via transmission of ultra wideband pulses. The device may be adapted to be worn external to the person, or may be a second implant. So as to conserve battery power, the transmitted ultra wideband pulses may have a low duty cycle of approximately 1 / 1000 or less. Power savings may also be realized by using time-gating amplifiers in the implant and / or device receiver.

Middle Ear Implant for Otosclerosis

ActiveUS20120220818A1Deaf-aid setsMedicineTransducer
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.

Optically coupled acoustic middle ear implant systems and methods

An assembly comprising a sound transducer can be implanted in the middle ear in a manner that simplifies surgery. The assembly may comprise a narrow cross-sectional profile such that the assembly can be positioned in the middle ear through an incision in the eardrum, for example without cutting bone. The incision can be closed and electromagnetic energy transmitted through the closed incision to a transducer configured to vibrate the ear in response to the electromagnetic energy. In many embodiments, the sound transducer comprises a speaker positioned in the middle ear, and the sound transducer can couple to vibratory structure of the ear with air so as to simplify surgery. The assembly may be affixed to a substantially fixed structure of the ear, for example the promontory, so as to inhibit user perceivable occlusion and inhibit motion of the assembly, such that the user can perceive clear sound with little occlusion.

Universal Bone Conduction and Middle Ear Implant

A middle ear implant system includes a bone conduction transducer configured for fixed attachment to skull bone of a patient beneath the skin behind the ear, and for generating sound vibrations from an external communications signal received through the skin for coupling to the skull bone for bone conduction sound perception by the patient. A malleable ossicle connector is connected to the bone conduction transducer and a middle ear hearing structure of the patient. And one or more isolation springs are configured for placement at the fixed attachment of the bone conduction transducer to the skull bone to acoustically decouple the bone conduction transducer from the skull bone to avoid bone conduction sound perception so that sound perception from the external communications signal is solely via the middle ear sound perception from vibrations coupled to the middle ear hearing structure by the ossicle connector.
