Abstract

A dermal tissue allograft includes a dermal matrix having a profile including first and second vertices, a first imaginary axis extending between the first and second vertices, a first peripheral edge extending along a continuous path from the first vertex to the second vertex on a first side of the first imaginary axis, and a second peripheral edge extending along a continuous path from the first vertex to the second vertex on a second side of the first imaginary axis. The first peripheral edge includes an apogee, a convex portion, and a concave portion. The convex and concave portions meet at a transition point located on the first peripheral edge between its apogee and the second vertex. The second peripheral edge includes an apogee and is convex. The second perpendicular distance is greater than the first perpendicular distance. The dermal matrix has a substantially uniform thickness across its profile.
