• NerVFIX

NerVFIX®

NerVFIX® is a devitalized, viro-inactivated, freeze-dried, sterile nerve regeneration conduit derived from umbilical cord veins and arteries. It promotes nerve regrowth from gaps of up to 2 cm in the nerves of the hand and wrist, and sensory-motor recovery from nerve transection.

It is authorized by the Paul-Ehrlich-Institut and approved by the ANSM for peripheral nerve regeneration procedures (notably hand surgery).

The benefits

At TBF, we design our grafting products with a constant focus on quality, safety and clinical performance. Every PHOENIX® bone graft is prepared according to rigorous, scientifically validated processes that comply with the most stringent regulatory requirements.

Biological structure

Its tubular biological structure enables rapid, targeted axonal regrowth with remyelination (motor and sensory recovery).

Product features

The NerVFIX® conduit is biocompatible and resorbable in 8 to 12 weeks. It does not collapse because the vessel wall is on the outside and Wharton’s jelly is on the inside. It is flexible and easy to cut and suture

Proof of effectiveness

A multicentre, prospective Phase ll clinical trial has been carried out, validating nerve regeneration with NerVFIX® after nerve transection in humans.

A unique, controlled production process

NerVFIX® is biocompatible and resorbable in 8 to 12 weeks. It does not collapse, as the vessel wall is on the outside and Wharton’s jelly is on the inside. It is flexible, easily cut and sutured.

NerVFIX® conduit is derived from umbilical cord veins and arteries, harvested during childbirth in strict compliance with Good Tissue Harvesting Practices and Bioethics legislation. It is processed at the TBF Tissue Bank using the AMTRIX production and safety process.

  1. Clinical and biological selection

    Umbilical cord vessels from living, consenting donors.

  2. Mechanical treatments

    Turning Inside-out vessels. Length cutting.

  3. Chemical treatments

    Deep cleaning, devitalization and viral inactivation.

  4. Lyophilization

    In order to dehydrate the tissue thoroughly and reproducibly, guaranteeing long-term preservation of the tissue’s characteristics at room temperature.

  5. Gamma radiosterilization

    This process, with its narrow sterilization range (maximum 32 kGy), preserves the biological and structural quality of the tissue, while enabling effective sterilization to ISO11137 standards.

  6. Final release and storage

    Shelf life 5 years at room temperature.
