Medical history
Amniotic membrane has been used in medical care for decades.

Thoughtful care.
With you in mind.
Getting ready for surgery can bring a lot of questions. Understanding the choices in your care plan can help you feel more prepared.
Your surgeon may recommend EvoPatch as a donated tissue covering at your surgical site. Here’s what that means, and what you can ask before your procedure.
Donated tissue. A place in your care.
What is EvoPatch?
EvoPatch is donated human placental tissue, supplied as a thin, flexible sheet made from two layers of amniotic membrane.
It contains amnion, without a chorion layer. This donated tissue is called an allograft: human tissue used in another person.
Why your surgeon may choose it
Its sheet format provides continuous tissue coverage over a selected area. Your surgeon chooses the size and placement to suit the tissue surface and your procedure.
Amnion tissue has been studied for its potential to aid healing. Your surgeon may choose EvoPatch as a protective covering within your healing plan. Ask about the potential benefits and evidence for your procedure.
Placed with your care in mind
Part of your
personal care plan.
Your surgeon may choose EvoPatch as an additional tissue covering at a wound or surgical site.
Ask whether tissue coverage may be appropriate for your procedure. Your clinician determines suitability and placement, consistent with the Instructions for Use.
Settings to discuss
- Colorectal and gastrointestinal surgery
- Obstetric and gynecologic procedures
- Urologic procedures
- General surgery and surgical oncology
- Cardiothoracic, thoracic, and vascular procedures
- Other procedures where wound covering may be appropriate
A history of birth-tissue care
A foundation in medical care.
Research on amniotic membrane grafts has reported encouraging findings in specific settings.
These studies evaluated products different from EvoPatch. Ask your surgeon about EvoPatch-specific evidence and possible benefits for your procedure.
Wound healing
Some wound-care studies have found faster healing with amniotic membrane dressings.

Tendon-repair research has examined reducing adhesions: bands of scar tissue that can limit movement.

Some burn research has reported less raised scarring after skin grafting.

A careful approach
to tissue safety.
Donated tissue undergoes screening, processing, and sterilization before it is available for use.
Carefully screened donors
Donated human tissue is screened before it is made available for patient care. Your surgeon can explain the screening and processing steps that apply to EvoPatch.
Processed and sterilized
EvoPatch is supplied sterile and is sterilized using gamma irradiation.
A brief safety note
Tell your care team about allergies, sensitivities, and any unexpected reaction.
Your surgery. Your questions.
Make it part of
your conversation.
If your surgeon recommends EvoPatch, ask how this tissue covering fits into your procedure and care plan.
Take these questions to your next visit, or share the patient brochure with someone helping you prepare.
- Where will EvoPatch be placed during my procedure?
- Why is this tissue covering a good fit for my surgical site?
- What benefit do you expect, based on my procedure and the evidence?
- What should I know about recovery, risks, and alternatives?
- Will it add any cost, and what might I need to pay?
Plan for costs, too
Before your procedure, ask your physician or facility whether EvoPatch adds any cost, whether insurance may cover it, and what you may need to pay.
A little more clarity
Common questions.
Does EvoPatch replace my usual care?
EvoPatch may be included as a tissue covering within your care plan. Follow your surgeon’s instructions for your procedure, recovery, and follow-up appointments.
Will it help me heal or prevent scarring?
Studies of other amniotic products have reported encouraging findings in particular settings. Those results do not establish how EvoPatch will affect your recovery. Ask your surgeon what benefit they expect for your procedure and what evidence supports that expectation.
How is it applied?
The care team uses sterile handling techniques. Your surgeon places the sheet over the area where wound covering is appropriate. It may be used dry or hydrated with sterile saline at the clinician's discretion.
Who should I contact with a concern?
Your surgeon or care team is your first point of contact for questions about your procedure or recovery. Contact them promptly about an unexpected reaction.
