Patent ID: 8821585

Claim:
A composite implant comprising: a tissue reinforcing film having a first major surface and a second major surface, said tissue reinforcing film having anisotropic properties so that said tissue reinforcing film is more stretchable along a first axis and less stretchable along a second axis that traverses the first axis; an asymmetric alignment marker overlying said first major surface of said tissue reinforcing film; an absorbable film overlying said alignment marker and said first major surface of said tissue reinforcing film, wherein said alignment marker is laminated between said absorbable film and said first major surface of said tissue reinforcing film, and wherein said asymmetric alignment marker includes first and second marking lines extending along the first axis for indicating the orientation of the more stretchable first axis and a central region positioned at a center of said tissue reinforcing implant and extending along the second axis for indicating the orientation of the less stretchable second axis, said first marking line extending from a first side of said central region, and said second marking line extending from a second side of said central region, said first and second marking lines having different widths for distinguishing a first end of said composite implant from a second end of said composite implant, and said central region of said asymmetric alignment marker having a width that is greater than the respective widths of said first and second marking lines.
