Abstract
Described herein are placental tissue grafts produced by chemical dehydration followed by freeze-drying the placental tissue to produce the tissue graft. The tissue grafts retain their biological properties preferably at the same level as the placental tissues before they are processed. The placental tissue grafts have numerous medical applications. Methods for making the tissue graft compositions are also described herein.
Claims46
A placental tissue graft produced by a method comprising:
- a. chemically dehydrating a placental tissue;
- and
- b. freeze-drying the placental tissue to produce the tissue graft.
A placental tissue graft comprising at least two layers of chorion, at least two layers of amnion membrane, or at least one layer of chorion and at least one layer of amnion membrane, which is produced by a method comprising:
- a. chemically dehydrating a placental tissue comprising at least two layers of chorion, at least two layers of amnion membrane, or at least one layer of chorion and at least one layer of amnion membrane;
- and
- b. freeze-drying the placental tissue to produce the tissue graft.
A method for producing a placental tissue graft comprising:
- a. chemically dehydrating a placental tissue;
- and
- b. freeze-drying the placental tissue to produce the tissue graft.
