INFLATABLE HERNIA PATCH
First Claim
1. A patch for repairing an intra-abdominal defect, the patch comprising:
- a mesh layer comprising a grid of material perforated by apertures through the mesh to reinforce an area around an intra-abdominal defect, the mesh layer having an edge;
a containment layer secured proximate the edge of the mesh layer;
a filler distributed across the apertures of the mesh to contain a fluid from passing through the mesh; and
the mesh layer, containment layer, and filler connected to form a chamber to selectively expand upon receipt of a quantity of fluid between the containment layer and the filler.

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.

18. A method for repairing an intra-abdominal defect, the method comprising:
-
providing a patch comprising a mesh layer integrated with a fluid chamber expandable to extend the mesh layer; folding the patch; inserting the patch through an incision in the abdomen to repair an intra-abdominal defect; unfolding the patch by urging fluid into the fluid chamber; positioning the patch over the intra-abdominal defect; attaching the patch to the abdominal wall to reinforce an area proximate the intra-abdominal defect; and leaving the fluid chamber within the abdomen upon closing the incision. - View Dependent Claims (19)

20. A patch for repairing an intra-abdominal defect, the patch comprising:
-
a mesh for attachment to an area proximate an intra-abdominal defect; a fluid chamber integrated into the patch and connected to the mesh, wherein the fluid chamber upon inflating extends to maintain the shape of the mesh to facilitate placement and attachment of the mesh proximate the intra-abdominal defect.
