Product Information

Designed for external vocal fold medialization using a surgical approach developed, simplified and standardized by Prof. Gerhard Friedrich MD, (Graz, Austria).

Because of its cleverly simple and precisely engineered design, the TVFMI™ implant makes a vast multiplicity of shapes and sizes redundant. In fact, two sizes (one for men, one for women) and one instrument suffice to develop the variety of adaptations that may be required during surgery. For rare cases a special small size (11 mm) is additionally available.

The implant facilitates a precise medialisation and can easily be fixed due to its design. This helps reducing the risk of dislocation. 



  • Optimized implant placement through a customized design
  • No additional sizer or instrumentation necessary
  • Helps minimising inventory levels
  • Reversibility
  • Local anesthesia makes intraoperative speech function testing possible
  • Reduced risc of dislocation
