Abstract

A composite implant includes an anisotropic surgical mesh having more stretchability along a first axis and less stretchability along a second axis that traverses the first axis, and an alignment marker overlying a first major surface of the anisotropic mesh and extending along the first axis. The implant includes a first absorbable, anti-adhesion film overlying the alignment marker and the first major surface of the anisotropic mesh, and a second absorbable, anti-adhesion film overlying the second major surface of the biocompatible mesh. The alignment marker is disposed between the first and second absorbable films and the first and second absorbable films are laminated to the anisotropic mesh.
