New Possibilities in Vibroplasty
The Vibrant Soundbridge has proven to be an effective
and reliable middle ear implant over many years.The
system consists of an internal and an external
component.
The external component, the Amadé audio processor,
offers the latest hearing technology combined with
enhanced features. The internal implant contains the
innovative patented technology of the FMT which can
be used in a very flexible way to optimally compensate
different kinds of hearing loss.
A feature unique to the Vibrant Soundbridge is the
single point attachment of the FMT.This means that
the FMT is only attached to the structure of the middle
ear which it is stimulating. It is not fixed to the mastoid.
Vibroplasty
This versatility of the FMT has led to successful surgical
applications, called Vibroplasty. Vibroplasty is the
treatment of hearing loss via vibratory stimulation in
the middle ear. For mild to severe sensorineural hearing
loss as well as for conductive and mixed hearing losses,
the different treatments have proven to be safe,
effective and reliable in various complicated middle ear
conditions.
Alongside the existing and very successful ways of
placing the FMT, such as the Incus or the Round
Window Vibroplasty, Vibroplasty Couplers1 now offer
additional ways of attaching the FMT in the middle ear.
This allows even more surgical flexibility in a variety of
conditions and anatomies. Vibroplasty Couplers are
attached to the FMT and couple the FMT stimulation to
various middle ear structures.
1 Vibroplasty Couplers were developed together with Prof. K.-B. Hüttenbrink from Cologne and Kurz GmbH, Germany

Vibroplasty TM Couplers
OVAL WINDOW
When there is no stapes super structure, a
Vibroplasty-OW-Coupler can be placed directly
onto the stapes footplate.
* Cartilage in OW niche to stabilize assembly.
HEAD OF THE STAPES
Alternative coupling aids for the FMT
attachment to the head of the stapes are
available in Vibroplasty-CliP-Coupler and
Vibroplasty-Bell-Coupler design.
Advantages:
• Standardized procedure in the oval
window region
• Uses natural pathway of sound
• Available in different sizes
ROUND WINDOW
When the anatomy does not allow for a perpendicular
placement of the FMT to the round window membrane,
a Vibroplasty-RW-Coupler can be used as an
alternative coupling aid.
Advantages:
• More flexibility in Round Window Vibroplasty
• Adapts to fit smaller round window diameters
• Less drilling in many cases
* Cartilage to give pre-stress.
