This disclosure describes a membrane configured to guide bone and tissue regeneration for a bone defect. The membrane may comprise a first layer, a second layer, one or more perforations, a binder, and/or other components. The first layer of the membrane may be configured to contact bone. The first layer may include pores configured to promote ingrowth of bone regenerating cells into the first layer. In some implementations, the first layer may be a continuous sheet of microporous material without large perforations. The second layer may be configured to substantially prevent fibrous connective tissue from growing into the bone defect. The second layer may comprise a relatively dense structure. The second layer may be fixedly coupled to the first layer. In some implementations, the perforations may comprise co-axial through-holes having common dimensions through the first layer and the second layer. The perforations may be configured to enhance ossification.

Device for guided bone and tissue regeneration

A composite multi-layer material may generally comprise a d-PTFE material combined with an open structured material (either resorbable or non-resorbable) creating a composite multi-layer material. Attachment of the layers may be accomplished by stitching layers of material, exertion of hydraulic or other pressure, application of a biocompatible adhesive or heat, or some combination of the foregoing. Use of a d-PTFE, unexpanded material has multiple alternative uses, including without limitation, placement on the visceral side of a hernia that may minimize or even eliminate the incidence of abdominal adhesions. Alternatively, the material may be used to create tubing sufficient as a graft for treating abdominal aortic aneurysms.

PTFE composite multi-layer material

A medical barrier includes a sheet of unsintered substantially unexpanded hydrophilic polytetraflouroethylene (PTFE) polymer material. A PTFE polymer material is described that has a density in a range of about 1.2 gm/cc to about 2.3 gm/cc, and preferably in the range of about 1.45 gm/cc to about 1.55 gm/cc, and having at least one textured surface. In accordance with one embodiment, the sheet has one textured surface and one substantially smooth surface, and has substantially uniform strength in all directions.
