Claim:
1. A placental tissue assembly for treating wounds or surfaces of a patient, the assembly comprising: one or more dried layers of placental tissue having a first side and a second side; a backing material adhered to and covering one of either the first or second sides of the one or more dried layers of placental tissue to create an assembly wherein the backing material is permeable to liquids and wherein moistening of the backing material wets the adhered surface of the covered first or second side of the one or more dried layers which reduces the adherence to the first or second side of the one or more dried layers allowing the backing material to slip relative to the wetted surface of the placental tissue to release from the one or more layers; a releasable peelable or peel-off cover attached to the first or second side opposite the backing material and wherein the releasable peel-off cover is cut or formed as two pieces with abutting edges wherein the abutting edges lift from the attached position on bending of the assembly to facilitate peeling from the assembly prior to applying to the surface to be treated; and wherein the assembly when applied onto a wound or surface to be treated on the side of the tissue opposite the backing material adheres to the wound or surface with an attachment force greater than an attachment force of the moistened backing material adhered to the first or second side, thereby allowing the backing material to be released leaving the placental tissue affixed to the surface to be treated.
