A translucent complete human placental membrane allograft

Revita Clear is a translucent dehydrated complete human placental membrane allograftA tissue graft from a donor of the same species as the recipient but not genetically identical.1 optimized for use as a wound covering or barrier membrane. It preserves all three layers of the placental tissue without disruption of the natural orientation during processing.2 Throughout the Clearify process, Revita Clear has been optimized to preserve extracellular matrix components, like collagens and glycoproteins, in a clear, compact format.2

Product Features & Benefits

Contains collagen and hyaluronic acid2
Excellent product handling2
Thicker than the leading dual layer allograft2
Protective, resorbableGradually breaks down and absorbs naturally into the body1 wound covering
Clear for increased application site visibility2
Compact for shallow tissue defects

Why is Revita Clear unique?

The use of placental tissues in wound care has been documented in medical texts since the early 20th century.3 There are three distinct layers that make up this membrane: the amnion layerThe amnion layer is the innermost layer of the placental membrane. This layer provides tensile strength and acts as a fibrous skeleton.4, intermediate layerThe intermediate layer exists between the amnion and chorion layers and is rich in collagens, proteoglycans, and glycosaminoglycans, like hyaluronic acid.4, and chorion layerThe chorion layer is the outermost, thickest layer of the placental membrane. It contributes to elasticity and membrane stability.4.4 The three layers function together to create the ideal protective covering and barrier between the mother and the fetus.

While most placenta-based products provide single or dual layer allografts, StimLabs has developed the first membrane allograft to retain all three layers of the membrane, including the intermediate layer.2 The preserved intermediate layer is a vital part of the membrane barrier property intrinsic to the tissue. The layer contributes to the overall composition of the allograft, containing extracellular matrix components like collagenProvides strength and structural resistance to degrading enzymes in native placental tissue.4, proteoglycansPromotes tissue hydration in native placental tissue.4, and glycosaminoglycans, like hyaluronic acidProvides lubricating and elastic properties in native placental tissue.4.4

How do we retain these beneficial components?

Clearify™ is a unique, patented processing approach to placental tissue that maximizes the retention of desired structural components, while effectively cleaning and terminally sterilizing the graft.2 The Clearify™ processing method, originally created specifically for Revita, is designed to preserve all three layers of the placental membrane.2 The Revita Clear allografts are oven-dried, using our patented dehydrated process, and never delaminated, meaning that the layers aren’t pulled apart in processing. This protects key components and natural architecture from being stripped away or damaged as the product is processed.2
