Abstract

Multilayer structures including a porous layer and a non-porous layer having a reinforcement member are useful as dural repair materials.

Claims

1. A dural repair material comprising a foam layer comprising a collagenic constituent joined to a fiber-reinforced film comprising a collagenic constituent.

4. The dural repair material of any of claims 1, 2 or 3 wherein the reinforcement member is a mesh.

5. The dural repair material of any of claims 1, 2 or 3 wherein the reinforcement member is embedded within the non-porous layer.

6. The dural repair material of any of claims 1, 2 or 3 further comprising a bioactive agent.

2. A dural repair material comprising a porous layer joined to a non-porous layer containing at least one fiber reinforcement member.

3. A dural repair material comprising a porous layer comprising a collagenic constituent sandwiched between a fiber-reinforced non-porous layer comprising a collagenic constituent and a second non-porous layer comprising a collagenic constituent.
