Clinical Study for the Treatment of Peripheral Nerve Defects With Neuromaix

The Neuromaix nerve guide is an absorbable implant composed of porcine collagen, used to bridge a peripheral nerve discontinuity, and to create a conduit for axonal growth across the nerve gap. Neuromaix provides a protective environment for peripheral nerve regeneration after injury. Neuromaix connects the proximal and distal ends of a transected nerve, allowing regenerating axons to grow through the scaffold, into the distal nerve tissue towards the target muscle or skin.

Neuromaix is composed of two parts. The Epimaix part provides the structural characteristics needed to suture the nerve guide in place and to prevent ingrowth of scar tissue. The Perimaix part provides a structure that mimics endoneurial tubes, providing guidance for the regenerating axons while bridging the nerve gap.
