Abstract
Abstract An implant and coverings for an implant for use in the human body are disclosed. Coverings for implants are constructed to present a biocompatible surface to the body and to provide a textured surface which serves to disorganize scar tissue which forms around the implant. Filaments of expanded PTFEe are attached to a stretch fabric backing in a loose weave configuration. Silicone molded in geometric patterns may be employed to present a textured surface. Compressive structures may be beneficially used on the surface of the implant or in the interior of the implant. Foam is one such compressive structure. Hexagonally shaped compressive cells containing fluid, gas, gel or foam are adapted to receive an insert which contains an outer biocompatible coating. A valve or port is provided to communicate between the cell and the body. Expansion means may be provided to expand the implant in a desired direction.
