1. A patch for repairing an intra-abdominal defect, the patch comprising:
- a mesh layer formed of a mesh material to be substantially flat;
a fluid chamber connected to the mesh layer to enclose a continuously connected space supporting a uniform pressure therein, the fluid chamber comprising the mesh material;
the fluid chamber sized and oriented with respect to the mesh layer such that inflation of the fluid chamber causes extension of the mesh layer; and
the fluid chamber comprising at least one of an inflatable ring and an inflatable rib.

Abstract
A patch for repairing an intra-abdominal defect is disclosed in one embodiment of the present invention as including a mesh layer providing a grid of material perforated by apertures through the mesh. This mesh is used to reinforce an area around an intra-abdominal defect. A containment layer is secured proximate an edge of the mesh layer. A filler is distributed across the apertures of the mesh to contain a fluid from passing through the mesh. The mesh layer, containment layer, and filler are connected to form a chamber to selectively expand upon receipt of a quantity of fluid between the containment layer and the filler.
