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.
A fixation element for an implantable microphone, wherein 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 surrounding an outer circumferential portion of a housing part of the microphone, which housing part is provided with a sound receiving member, the ends of said cylindrical portion each being provided with a flange member which, in the implanted state of the fixation element, contact one side each of the wall of the auditory canal, and wherein said cylindrical portion is provided at the outer circumference thereof with axially extending protruding web elements of elastic material which, upon insertion of the cylindrical portion into the bore, contact the wall of the bore under the influence of elastic restoring forces.
A fixation element for an implantable microphone, said fixation element comprising first and second members, wherein said first member has a stud adapted for insertion into a bore which crosses a wall of the auditory canal of a user, wherein said stud has a first free end and an opposite second end and encloses a housing part of the microphone at the outer circumference thereof, which housing part is provided with a sound receiving member, and wherein said second member comprises a first flange portion and a sleeve portion, said sleeve portion having opposite first and second ends and being adapted to be slipped, starting with the first end thereof, over said first end of said stud and to be engaged with the stud for preventing at least relative axial movement between the stud and the sleeve portion, and said first flange portion being provided at the second end of the sleeve portion and being adapted to engage, in the implanted state of the fixation element, the side of the wall of the auditory canal facing the skin of the auditory canal.
A fixation element for an implantable microphone, wherein the fixation element comprises a cylindrical portion adapted to be inserted into a bore which crosses a wall of the auditory canal of a user, said cylindrical portion surrounding an outer circumferential portion of a housing part of the microphone, which housing part is provided with a sound receiving member, wherein said cylindrical portion is provided at a first end thereof with a first flange portion which, in the implanted state of the fixation element, contacts a side of the wall of the auditory canal facing the skin of the auditory canal, wherein said cylindrical portion is provided with a second flange portion which, in the implanted state of the fixation element, contacts a side of the wall of the auditory canal remote from the skin of the auditory canal, wherein said first flange portion is comprised of a plurality of circumferentially spaced elastic first holding tongues, wherein first recesses are provided in the outer circumference of the cylindrical portion, and wherein said first holding tongues are adapted to be folded towards and received by said first recesses to facilitate introduction of the cylindrical portion into said bore.
A fixation element for an implantable microphone, wherein the fixation element comprises a stud adapted to be inserted into a bore which crosses a wall of the auditory canal of a user, said cylindrical portion surrounding an outer circumferential portion of a housing part of the microphone, which housing part is provided with a sound receiving member, wherein said stud is provided at one end thereof with lamellas which are distributed in circumferential direction of the stud, wherein said lamellas have one end thereof pivotally connected to the circumference of the stud, and wherein said lamellas, in the implanted state of the fixation element, contact a side of the wall of the auditory canal facing the skin of the auditory canal.
