NITIFLEX STAPES PROSTHESIS

EVOLUTION OF THE CLIP STAPES PROSTHESIS
One important milestone in the evolution of stapes prostheses is the
development of the NiTiFLEX. Its proven CliP technology standard-
izes the coupling of the prosthesis to the long process of the incus
increasing the likelihood of a good postoperative outcome.

SUPERELASTIC NITINOL
As opposed to conventional CliP prostheses, the NiTiFLEX has a
loop made of superelastic nitinol which considerably reduces the
attachment force. Extensive simulation and test series during the
development process aimed to further enhance the transmission
properties of the prosthesis.

REDUCED PRESSURE TOWARD INNER EAR
The prosthesis does not completely surround the incus. Later-
ally and medially there are prosthetic contact zones for a re-
liable acoustic sound transmission. The attachment direction
minimizes the risk of adding pressure in the direction of the
inner ear. In addition, contact-free zones ensure continuous vascular
nutrition of the mucosa. A wide, flat CliP band minimizes pressure
peaks and may reduce the risk of necrosis.

The NiTiFLEX is available in all standard lengths (see table below).
Easy insertion with the aid of the Soft CliP Hook (REF 8000 127).

Developed in close collaboration with Tuebingen University
ENT Clinic and the Institute of Engineering and Computational
Mechanics at the University of Stuttgart (ITM), Germany.
