Artacent Amniotic Tissue for Treatment of Chronic Lower Extremity Diabetic Ulcers.

This is study is to determine if A tri-layered dehydrated human amnion/chorion/amnion composite graft would help non-healing lower extremity diabetic ulcers to heal over a 12 week time period. During this trial the patient will undergo a screening period where SOC is used to see if the patient will respond and heal \> 20% of the surface area in 2 weeks. if the patient can not heal more than 20% in two week the patient then will receive a trial-layered human amnion/chorion/amnion composite graft weekly for 12 week and precent wound area reduction and complete wound healing will be recorded.
