Flat implant for use in surgery
First Claim
1. 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, the micropores being so small that they permit an exchange of materials, but substantially prevent the growing in of cells, and wherein an additional adhesion prevention is provided by a bioabsorbable component which has a sealing effect.

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.

40. A hernial implant comprising a flexible flat three-layered structure including a three-dimensional textile support microstructure permitting a growing in of cells, a substantially closed layer or micropores having a pore size to permit an exchange of materials, but substantially prevent the growing in of cells, and superimposed thereon an additional top layer of a bioabsorbable component which has a sealing effect for adhesion prevention.
