Pure titanium body and piston end
Flat wide loop band reduces risk of pressure points. Loop is designed to control heat transfer to the incus mucosa.
Crimp-free coupling: Three laser activated ThermoActive activation zones. Elasticity of the activation zones ensures uniformly attachment. Four contact zones interface with the surface of the mucosa.

Product Information


The NiTiBOND Stapes Prosthesis is a crimp-free prosthesis, that combines proven properties of CliP Stapes Prostheses with the benefits of shape memory heat activated nitinol. Extensive experience in the development of stapes prostheses, knowledge of the middle ear, creates the basis for a geometry of the unique nitinol loop making it suitable for almost all incus sizes.

The nitinol loop has four integrated contact zones, conforming to the asymmetrical dimensions of the incus. Additionally, the loop also features three independent activation zones which keep thermal transfer from the mucosa surface during laser activation. These activation zones can be sequentially closed producing a custom coupling to the individualized incus.

The laser settings are determined outside the middle ear with the aid of the Thermo-Dummy. The dummy is delivered together with the NiTiBOND.

Developed in close collaboration with the ORL Clinic of the University Hospital Zuerich and the Institute of Engineering and Computational Mechanics at the University of Stuttgart, Germany.


  • Suitable for almost all incus sizes
  • Reduced risk of pressure points
  • Minimized head transfer to the mucosa
  • Reduced risk in laser setup
