摘要:
A secondary electrochemical cell with at least one positive electrode includes an active material and one negative electrode, which are held directly in a hermetically tight housing which has at least one detector element or which is dynamically connected to one such detector element. The detector element is designed or can be set to acquire a predetermined unallowable operating state of the secondary electrochemical cell, and in an unallowable operating state of the secondary electrochemical cell, to actuate at least one switching element which prevents recharging and/or discharging of the secondary electrochemical cell. By making the housing as a hermetically tight protective housing, which is part of an implantable medical device, contamination of surrounding tissue with toxic substances and hazard to the implant wearer by the malfunction of the secondary electrochemical cell can be precluded under all operating conditions with simultaneously great reduction of all dimensions.

A hearing instrument with at least one microphone and signal processing includes at least two receivers having a different frequency response. At least a first one of the receivers can be placed outside the ear canal, for example in a behind-the-ear component. A behind-the-ear component and an external component can be provided for being placed in the user's ear canal or in the user's ear with a connection link between the behind-the-ear component and the external component. The sound processing means can feed the first receiver with a first signal of a first central frequency and the second receiver with a second signal of a second central frequency. The signal processing means can be one or two signal processing units. A frequency separating filter can have an input operatively connected to an output of the signal processing unit.

摘要:
A fixation element for an implantable microphone is disclosed. In a preferred embodiment the fixation element comprises an essentially cylindrical portion adapted to be inserted into a bore which crosses a wall of the auditory canal of a user, said cylindrical portion, at least in an implanted state of the fixation element, surrounding an outer circumferential portion of a housing part of the microphone, which housing part is provided with a sound receiving member. The cylindrical portion includes at least one elastic region of increased diameter, said elastic region contacting, in the implanted state of the fixation element, a wall of said bore and providing, by elastic restoring forces, for a friction which is sufficiently high to fix said cylindrical portion in at least one of the two axial directions of said bore.

The invention relates to a partially or fully implantable hearing system which is provided with a unit (14, 30; 460) for electromechanical or electroacoustic stimulation of the middle ear or inner ear or direct electrical stimulation of the inner ear. The hearing system furthermore comprises means (26, 126, 154, 526) for direct linkage of the hearing system to telecommunication networks without using telecommunication terminal devices.
摘要:
Device for electromechanical stimulation and testing of the hearing, including an electromechanical transducer for producing mechanical vibrations, a mechanical coupling element for transmitting mechanical stimulation vibrations from the electromechanical transducer without surgery through the external auditory canal to the umbo, and thus, to the manubrium malleli of the ossicular chain, a positioning device for positioning the coupling element with reference to the umbo, and a fixing device for secure, play-free linkage of the positioning device to human body, especially the human skull. An intermediate element is provided between the positioning device and the electromechanical transducer, said intermediate element being designed and dimensioned such that the intermediate element transmits quasi-steady-state positioning adjustments from the positioning device to the transducer, but reduces transmission of at least dynamic forces from the positioning device to the coupling element at least to such an extent that the risk of middle or inner ear damage is substantially reduced.
摘要:
A power supply module (58) for an implantable device (54) has a biocompatible outer housing (80) which holds a repeatedly rechargeable electrochemical battery (90) that supplies electrical power to a main module (56) of the implantable device (54) via a coupling element (82). The outer housing is made as a hermetically tight protective housing or holds such a housing (88). The protective housing (88) has a detector element (92) which is designed or adjustable to actuate at least one switching element (94) which prevents recharging and/or discharging of the battery (90) when the battery is in an unallowable operating state. The coupling element (82) is preferably made detachable.
