Evologics Allograft Tissue For Wound Covering

Resorbable Amniotic Membrane Allografts


Minimally Manipulated Amniotic Tissue

Evologics Allograft Tissue can be used in open incision, laparoscopy and/or robotic surgery procedures, and may facilitate in healing and repairing wounds.

Available in single layer, dual layer and chorian.

EvoPatch Amnion Patch
  • Available in 1 cm X 1 cm up to 4 cm X 8 cm sizes
  • Single and Dual Layer Chorion Free
  • New: Chorion Patches in all sizes

Wound Healing Properties

Amniotic membrane contains a complex mix of wound healing components including growth factors, cytokines, amino acids, carbohydrates, hyaluronic acid, and extracellular matrix (ECM) proteins that are known to aid in the healing and repair of wounds.


Unlike other amniotic tissue allografts on the market, Evologics single and dual layer amnion allografts do not contain chorion, which reduces the risk of an adverse reaction in the patient.

What is Amnion?

Evologics amnion patches contain natural growth factors, and is used by many physicians to treat patients with hard and soft tissue injuries, to decrease inflammation, to help repair and alleviate pain caused by joint injuries, to reduce scarring, and to facilitate healing.

How is Amnion Sourced?

The amniotic membrane tissue process involves the recovery of the amniotic membrane that surrounds the baby during planned, full-term Caesarean sections. Amnion is taken only from healthy, pre-screened, consenting mothers who have been tested for infectious diseases, and undergone comprehensive testing, including behavioral risk assessment, physical assessment and communicable diseases. Evologics amnion allografts are acquired and processed in the United States adhering to American Association of Tissue Banks (AATB) and the United States Food and Drug Administration (FDA) rules, regulations and standards.
