The new NiTiBOND® Stapes Prosthesis is created by combining the features of KURZ CliP® stapes prostheses with the shape memory effect of Nitinol.
Surgical experience with a wide range of stapes prostheses and thorough understanding of middle ear mechanics provided the key input for the design of the unique new loop. It not only facilitates the surgical coupling to the incus but also further enhances the safety and effectiveness of implant ossicle attachment for the patient. The NiTiBOND® Stapes Prosthesis is the result of a multi-stage development project in close conjunction with the ORL-Clinic of the University Hospital of Zurich, Switzerland, and the Institute of Engineering and Computational Mechanics, University of Stuttgart, Germany.
The flat band diffuses the impact of pressure on the incus. When applying heat to the ContactFree Zones, the shape memory properties of Nitinol cause the loop to close. The ContactFree Zones function as thermal blockers, limit heat dispersion on the mucosa and minimize the risk of incus and mucosa strangulation.
Except for the Nitinol loop, the entire prosthesis is made of pure titanium (ASTM F67 Standard). As with other KURZ stapes prostheses, the surface is smooth and all edges have been rounded to minimize the risk of injury within the perilymphatic space.
The Thermo-Dummy® provided in the plastic container together with the NiTiBOND® Stapes Prosthesis gives the user the opportunity to determine the optimal laser setting outside the patient’s middle ear and thereby increasing the potential for surgery success.
Prosthesis and Thermo-Dummy® in the plastic container.
Raise the Thermo-Dummy® with a fine instrument (Hook).
The laser can be evaluated by using the Thermo-Dummy®.
When the optimal laser setting has been established the NiTiBOND® Stapes Prosthesis is ready to use.
Using the laser setting determined with the Thermo-Dummy®, apply the first laser shot to the first ThermoActive Zone (1) on top of the loop.
Apply the second shot to the ThermoActive Zone (2) in center position.
Finally the third zone (3) located closest to the prosthesis shaft is closed..
