Reaxon® Nerve Guide

Reaxon® Nerve Guide is a flexible, long-term biodegradable nerve guide for bridging nerve defect lengths up to 26 mm. It directs the sprouting nerve fibers and inhibits the ingrowth of scar tissue und neuroma formation. Reaxon® Nerve Guide is made of a transparent chitosan hydrogel which facilitates the transport of nutrients and oxygen to the regenerating nerve.
