Abstract
A flat implant for use in surgery is described. The implant includes a flexible fabric comprising two sides and having on one side a substantially closed surface and on the other side a three-dimensional microstructure permitting a growing in of cells. The implant can be more particularly used for the treatment of wall defects in body cavities, such as abdominal wall defects.

A flat implant for use in surgery, the implant comprising a flexible fabric comprising two sides and having on one side a substantially closed surface and on the other side a three-dimensional microstructure permitting a growing in of cells, wherein the substantially closed surface comprises micropores, wherein the micropores permit an exchange of materials and are sufficiently small to prevent the growing in of cells, the closed surface being formed by a surface layer connected to the flexible fabric as a coating formed by spray coating of a web of a polymer, and the three-dimensional microstructure having back-engagement points for the growing in of cells formed by at least one of a woven fabric and a knitted fabric, the implant having an air permeability of 5 to 100 ml of air/cm2.min at a pressure difference of 1.2 kpascal.
