Axoguard Nerve Protector®

Axoguard Nerve Protector is the only small intestine submucosa (SIS) implant designed to protect injured and compressed nerves up to 40 mm.

Barrier to soft tissue attachments1

protector innovations

  • Provides a protective barrier to separate the nerve from the surrounding tissues.1
  • Minimizes the potential for soft tissue attachments to allow the nerve to glide.1
  • Vascularizes and remodels into the patient’s own tissue.1
  • Available in a variety of lengths and diameters for intra-operative versatility.

the importance of biomaterials

In a pre-clinical study conducted to evaluate host tissue response, porcine small intestine submucosa (SIS, Axoguard Nerve Connector) performed significantly better than cross-linked bovine collagen type I (CLC, Integra NeuraGen®) in all outcomes and categories.

Specifically, the study provided evidence that SIS had increased levels of M2 (pro-healing) macrophages which are indicative of a remodeling response, while CLC had increased levels of M1 (pro-inflammatory) macrophages indicative of a chronic inflammatory response.2,3
