| 摘要 |
The invention relates to an implantable prosthesis for use in abdominal surgery, comprising two interconnected meshes which are stacked on top of one another. The outer mesh is intended to be placed on, and joined to the hole of the defect, while the inner mesh is placed on the inner side of said hole and extends significantly past the edges thereof. The inner mesh, which is designed to perform a containment function, does not have to be fixed owing to the positive pressure and the contents of the abdominal cavity. Moreover, the inner surface of said second mesh is covered with a fine layer which is in contact with the viscera and prevents adhesion formation and erosion of the viscera, by encouraging mesothelial cell deposition. In addition, both of the aforementioned meshes stimulate and modulate fibroblastic proliferation and collagen deposition in order to enable definitive repair of the defect at the expense of the connective tissue.
