Definitions

  • the present invention relates to a converter arrangement for partially or fully implantable Hearing aids for direct mechanical excitation of the middle or Inner ear, provided with one at the implantation site with reference to the skull fixable housing and a movable with respect to the housing, mechanically rigid coupling element, with an electromechanical in the housing Transducer is housed with which the coupling element vibrate lets that after implantation of the transducer assembly on Middle ear ossicles or directly to the inner ear.
  • Such a converter arrangement is known from EP 0 499 940. It is suggested that run a wall of the housing as a vibratable membrane, the with a piezoelectric ceramic disc attached on the inside represents electromechanically active heteromorph composite element. Although one hearing aid transducer arrangement constructed in this way can be easily implanted can and can generally achieve good results, but has shown that the coupling element driven via the piezoelectric ceramic disc with low to be transmitted to the middle ear ossicle or directly to the inner ear Frequencies deflections causes an adequate volume level may be insufficient for moderate and major hearing loss. This applies in particular to the low electrical values specified for an implant Tensions.
  • the solution according to the invention has the advantage that the transducer arrangement accordingly simple and easy like the piezoelectric transducer EP 0 499 940 can be implanted because the transducer housing is related can be fixed on the bone structure of the skull. At the same time, however, because of Use of the electromagnetic converter principle also for low frequencies particularly favorable frequency response of the transducer can be achieved in the listening area, so that an adequate listening impression with sufficient volume level with the in the case of an implant necessarily enables low electrical voltages becomes.
  • a wall of the housing can be designed as an oscillatable membrane be on the inside of which the vibratable component is attached and with whose outside the coupling element is connected.
  • the housing is useful as a hermetically sealed and biocompatible housing executed. It is advantageously cylindrical and has a peripheral wall and two circular end walls running essentially parallel to one another on one of which forms the vibratable membrane, while the others can be integrally connected to the peripheral wall of the housing.
  • Both the vibratable component and the coupling element are preferred essentially in the center of the housing end face forming the vibratable membrane attached.
  • the inside of the membrane is preferably a component that forms the oscillatable component Permanent magnet connected while an electromagnetic coil in the Housing is firmly attached to set the permanent magnet in vibration.
  • the permanent magnet is advantageously designed as a magnetic pin, and the Coil is a ring coil with a central opening into which the magnetic pin is immersed. In this way, a converter arrangement with a particularly small size received moving mass, the changes in the applied to the solenoid electrical signal can follow quickly and faithfully.
  • the invention also relates to a fully or partially implantable hearing aid is provided with a transducer arrangement of the type disclosed herein.
  • Fig. 1 is an implantable transducer assembly 10 of a hearing aid for direct mechanical excitation of the middle or inner ear.
  • For sound recording 2 serves as a microphone 58, preferably is also implantable.
  • the converter arrangement 10 is with a hermetically sealed, biocompatible, cylindrical housing 14, preferably made of Metal, for example titanium, niobium, tantalum, iridium or their alloys.
  • the housing 14 is filled with inert gas 16.
  • a pin-shaped permanent magnet 30 attached, which in a central opening of the Immersed coil 32 and is slidable therein.
  • the coil 32 is not shown in FIG shown firmly connected to the housing 14, for example with this glued.
  • an electrically insulating, hermetically sealed Implementation 26 used in the end wall 12 . Lead wires 34 of the coil 32 are with the outside connected out of the housing 14 electrical connections 36.
  • the coupling element 20 can in particular be used as a coupling rod trained and for example over a thin wire or hollow wire bracket or a bracket made of a carbon fiber reinforced composite material with the Ossicular chain connected. Suitable arrangements of this type are in the older one DE patent application 197 38 587.7 explained in more detail.
  • Fig. 2 shows an implanted hearing aid designated 51, which with a Transducer arrangement 10 of the type explained above is equipped.
  • the hearing aid 51 also has an accumulator unit 53, a charging / receiving coil 54 and an electronics module 55.
  • Components 53, 54 and 55 are in one hermetically sealed housing 56 which is implanted in the mastoid 57 and is fixed with respect to the skull.
  • To the electronics module 55 are the Transducer assembly 10 and microphone 58 via lines 59 and 60, respectively connected.
  • the coupling element 20 is coupled to the ossicle chain 62.
  • To a portable charging unit 63 includes a charging transmitter coil 64, which for transcutaneously charging the accumulator unit 53 with the charge receiving coil 54 can be coupled inductively.
  • a remote control unit is indicated at 65.
  • On such hearing aid is known for example from US Pat. No. 5,277,694 and therefore requires it no further description.
