NeuroShield’s chitosan hydrogel structure supports and protects the underlying nerve structure during soft tissue healing. Over time, the chitosan membrane naturally resorbs, degrading into compounds that may be beneficial for nerve regeneration.1-3


Along with the benefits of chitosan, NeuroShield offers the following handling characteristics based on its hydrogel structure:

> Transparent for easier membrane placement and repair visualization

> Soft, pliable and conforms to tissue

> Easy to suture, yet resists suture pull out

> One size wraps nerves up to 12 mm in diameter
