摘要： A set of fenestration burrs, for fenestrating otic capsule bone (34), includes an initial burr (150) and a sequence of fenestration polishing burrs (180). A polishing burr (152, 1521), of each of the burrs (150, 180), carries at least one spiraling flute (166, 166'). Fenestrations (36) piercing the bone (34) formed using the burrs (150, 180) exhibit uniform diameters while excluding bone dust from the inner ear. An implantable casing (72) includes a hollow collar (76) from which projects a hollow sleeve (74) receivable into the fenestration (36). The casing (72) is secured there by at least one prong (92, 102) jutting from the sleeve (74). A therapeutic appliance (134) is insertable into the casing (72). A flange (116) extending from one end of the sleeve (74) carries at least one L-shaped slot (122) open at one end and extending circumferentially around the flange (116).

摘要： A hearing aid includes an implantable microphone, signal-processing amplifier, battery, and microactuator. An electrical signal from the microphone is amplified and processed by the amplifier before being applied to the microactuator. The microactuator is adapted for implantation in a subject at a location from which it may mechanically create vibrations in the perilymph fluid within a subject's inner ear. A transducer of the microactuator is preferably a thin circular disk, 2 to 8 mils thick, of stress-biased PLZT. Disks of this stress-biased PLZT material can be mounted as drumheads in various different ways, preferably in conjunction with a flexible diaphragm, to small threaded metal tubes, e.g. 1.4 mm in diameter and 2.0 mm long. These tubes may be implanted into a fenestration formed through the promontory adjacent to the oval window of a subject's inner ear. Securing the disk to a tube having a larger diameter than that implanted into the fenestration and filling the tube with fluid provides hydraulic amplification of the transducer's displacement. The implantable microphone is preferably fabricated from a thin sheet of PVDF that is overcoated with inert metal electrodes.

摘要： Auditory system components and system adapted for implantation into a human subject for reducing conductive and/or sensorineural hearing deficiency in the subject. An electrically excitable microactuator is implantable either into a fenestration formed through a promontory or a stapes footplate which respectively separate a middle ear from an inner ear of the human subject. The auditory system also includes an implantable processor for supplying an electrical signal to the microactuator, and an implantable microsensor for transmitting an electrical signal responsive to impingement of sound on the microsensor.

摘要： A microactuator (32) of an implantable hearing aid system (10) is secured within a casing (50) implanted into a fenestration (52) that pierces the promontory (18) of the otic capsule bone (31). The casing (50) includes a hollow sleeve (62) that has an outer surface (64) and a first end (66) that is received into the fenestration (52). The sleeve (62) also includes an inner surface (68) adapted to receive a barrel (74) of the microactuator (32). The casing (62) also includes a flange (76) that is integral with the sleeve (62) and projects outward from the outer surface (64) of the sleeve (62) about a second end (78) of the sleeve (62). Various means secure the sleeve (62) within the fenestration (52) such as screwing into the promontory (18) or clamping to the promontory (18). The casing may fasten the microactuator (32) to the casing (50) by a threaded attachment, with screws, with button-and-socket snap fasteners, or with a slotted tongue-and-groove lock. A dummy plug may replace the microactuator (32) should removal become necessary.

摘要： An implantable auditory system for a human subject includes a microsensor, a processor and a microactuator. The microsensor is implanted in the middle ear to transduce sound waves into electrical signals. The processor is implanted in a hole surgically sculpted in the skull and controls amplification and processing of the electrical signals. The microactuator is micromachined from a single crystal and acts as a parallel plate capacitor, with a diaphragm spaced from the rest of the crystal by an extremely small void therebetween. The microactuator is implanted in the middle ear, and it may extend into the inner ear through a surgically formed fenestration or be mounted to the ossicular chain. Electrical signals conveyed to the microactuator set up electric fields across the narrow void and the diaphragm to produce electrostatic forces that cause the diaphragm to vibrate, thereby directly or indirectly vibrating fluid in the inner ear. Use of electrostatic forces to vibrate inner ear fluid reduces electrical current requirements, resulting in increased battery life.
