Nerbridge® is a product composed of polyglycolic acid and collagen derived from porcine skin. Nerbridge® is a flexible, resorbable and semipermeable tubular membrane matrix filled with porous collagen that provides a non-constricting encasement for injured peripheral nerves for protection of the neural environment. Nerbridge® is designed to be an interface between the nerve and the surrounding tissue. When hydrated, Nerbridge® is an easy to handle, pliable, soft, non-friable, porous conduit. The resilience of Nerbridge® allows the product to recover and maintain closure without constricting the nerve once the device is placed around the nerve. Nerbridge® is manufactured using validated viral inactivation and removal processes for the collagen. The product is provided in a foil pouch, sterile, non-pyrogenic, for single use only, in a variety of sizes, and placed in an outer Tyvek header bag for added protection.
An implantable tubular device intended to be used to create a tunnel through which a discontinuous peripheral nerve can regenerate to bridge the proximal and distal nerve stumps. The device is typically used during hand surgery and/or nerve reconstruction. It is made of an animal-derived material (e.g., porcine-derived collagen matrix, chitosan) that can be chemically degraded and typically absorbed via natural body processes. It is also known as a nerve sheath, nerve cuff, nerve protector, nerve conduit, or a nerve wrap.
