matrion™ decellularized placental membrane in subjects with diabetic foot ulcers

Conditions: Diabetic Foot; Lower Extremity Wound

Summary: in this study, a novel placental membrane product matrion™ (lifenet health, inc., virginia beach, va) will be used as a treatment for subjects with diabetic foot ulcers. matrion is composed of placental membrane derived from donated human birth tissue containing both the innermost amniotic layer and the outermost chorionic layer, inclusive of the trophoblast layer. matrion is minimally processed and disinfected using a proprietary decellularization technology and terminally sterilized that safely renders the placental membrane acellular and sterile for its intended surgical applications.
