摘要： A self-adjusting implantable cochlear implant system (46) includes an implant portion (50) and an external portion (53). The system provides a device and a way to objectively determine selected psychophysical parameters, such as stimulation threshold, comfort level and loudness resolution, used by the implant portion, which includes an implantable cochlear stimulator (ICS), as it carries out its stimulation function. The input to the system is an electrical stimulation. The outputs of the system include a middle ear reflex (MER) and evoked potentials, such as a compound action potential (CAP) along the auditory/cerebral pathways, both of which are sensed using objective measurement techniques and tools. In accordance with one embodiment, the adjustment process uses the MER for determining a coarse threshold value, and then (using such coarse threshold value as a starting point) uses evoked potentials to determine a more precise o fine threshold value, thereby zeroing in on a desired threshold. Such zeroing-in method is preferably carried out using implanted circuitry (e.g., included as part of the ICS), which implanted circuitry uses an implanted middle ear electrode (54) and a cochlear electrode (56), along with appropriate amplification (58, 64), filtering (60, 66) and processing circuitry (62, 68, 67), to respectively determine the MER response and evoked potentials. Another embodiment uses the presence or absence of the MER to adjust the intensity of electrical stimulation continuously and automatically, thereby relieving the patient from having to perform slow and tedious manual adjustments of the loudness control of a speech processor used with the ICS.

摘要： An implantable receiver (12) is powered and controlled by an external (not-implanted) transmitter (14) when a transmitter coil (22) is properly aligned with a receiver coil (20). No magnets are used in either the transmitter or receiver to achieve and maintain the needed alignment. Rather, a special set of implant tools (50) are used to assure that alignment is achieved and maintained between the implantable receiver (12) and external transmitter (14) when the implant operation is carried out. A preferred embodiment of the invention provides a magnetless implantable cochlear stimulator (ICS) (40) and a corresponding magnetless headpiece (30) worn behind the ear.

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： Implantable microphone for implantable hearing aids, which is used for excitation of hearing, such as cochlear implants or hearing aids with mechanical stimulation of the middle or inner ear, with a microphone capsule which is accommodated in a hermetically sealed housing, and with an electrical lead-in wire connector for connecting an implant line to the microphone module. The housing has at least two legs which are oriented at an angle relative to one another, one leg holding the microphone capsule and being provided with a sound inlet membrane, and the other leg containing the electrical lead-in wire connector. As a result of the two-legged geometry of the microphone housing, the microphone can be implanted after a mastoidectomy in the mastoid cavity such that the leg which has the sound inlet membrane lies in a hole in the posterior wall of the auditory canal so that, by mechanical contact of the membrane with the closed skin of the auditory canal wall, an acoustic signal incident in the external auditory canal is acoustically received, while the leg of the microphone housing containing the electrical lead-in wire connector is in the area of the mastoid tip. Completely implantable hearing aids for electrical excitation of hearing using the implantable microphone, can have, on the implant side, a battery arrangement for power supply which can be recharged transcutaneously via an external charging device. The audiological implant functions can, likewise, be transcutaneously controlled via a remote control.

摘要： An implant such as a cochlear assembly, or other similar device, includes an elongated therapeutic member arranged and constructed to perform a therapeutic function. The therapeutic member has at least two configurations: an insertion and a deployed configuration. The first configuration is selected to ease the insertion of the member into a body cavity. A stiffening member is used to urge said therapeutic member toward said first configuration. The stiffening member is made of a bioresorbable material so that after insertion, the stiffening member dissolves and allows the therapeutic member to assume the second configuration.

摘要： A multi-electrode cochlear implant is taught in which approximately twenty or more insulated metal wires are wound around a flexible tube. These wires are held in place with a further layer of dielectric insulating material. The insulation is selectively removed with a laser beam to form electrodes. Two or more layers or valences of wires can be used, with the inner layer of wires terminating distal to the outer layers to provide a stepwise approximation of the tapering of the scala tympani. A core of shape memory material may be introduced into the tube, so that the implant will retain an effective shape after implantation.
