A hernia repair implant (26) includes a first layer (58) made of mesh for facing a body structure having a hernia defect to cover the defect while promoting tissue growth into the first layer from the body structure. The implant also includes a second layer (60) opposed to the first layer and that extends radially beyond the first layer. The second layer is made of anti-adhesion material to prevent tissue growth into the second layer from body structures contacting it. The implant also includes a first elongated centering strap (34) connected to the first layer at a first radial location that extends radially beyond a periphery of the first layer, and a first elongated fixation strap (40) connected to the first layer at a second radial location that is more distanced from a center of the first layer than the first radial location and that extends radially beyond a periphery of the first layer.
