Abstract
Compositions comprising perforated, unseparated amnion/chorion; perforated, separated amnion; and perforated, separated chorion derived from the placenta and methods of preparing and using those compositions are provided. Perforation of placental tissue before or during processing may allow for one or more benefits such as more efficient removal of blood remnants, retention of wound healing and tissue regeneration components, better handling characteristics, or improved healing capacity. The present invention also includes methods of healing a wound of the skin, eye, nerve, tendon, or dura comprising applying the perforated compositions of the invention to the wound.
