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 standardizes 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. Laterally and medially there are prosthetic contact zones for reliable 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 also easily inserted with the aid of the Soft CliP Hook (Instrument).

This product has been developed in close collaboration with Tuebingen University ENT Clinic and the Institute of Engineering and Computational Mechanics at the University of Stuttgart (ITM), Germany.
