Ambio5® is developed to further optimize and simplify amniotic membrane transplantation (AMT) for eye surgery. The safety, logistical and surgical advantages with Ambio5 are vast.
A thicker membrane; biostructurally intact matrix.
Ambio5 yields a substantially thicker, structurally sound, native amniotic membrane allograft. While the proprietary Purion® tissue process destroys potential bioburden, the membrane's devitalized cellular components - along with its dense adjacent and connective matrices - are preserved.
- Nominal thickness: 100+ microns.
- Ambio5 is processed to a fuller thickness by retaining additional collagen matrices from the placental interface during processing.
- With the Purion® proprietary processing method, all antigens are removed; cells are devitalized; and final grafts are terminally sterilized.
Viable and Biostructurally Intact
- The scientifically-based Ambio5 process removes bioburden and potential virulency, but retains the devitalized, cellular components.
- Photomicrograph an intact columnar epithelial cell layer on the membrane’s surface; an intact, dense basement membrane; the presence of a loose collagen layer with fibroblasts; and an additional, thick layer of retained collagen from the placental interface.
Optimized Surgical Utility
- The free-standing configuration drastically reduces surgical time by eliminating the need for graft separation from nitrocellulose backing/substrate.
- This unique graft can be applied to the surgical site while dry, activated with sterile saline in minutes and then fixated into place.
Surface Orientation Identification
- The unique "watermark" impression on the Ambio5 allows for visual identification of the basement and stromal surfaces.
- The basement membrane can be easily identified by noting the proper vertical orientation of the "IOP" impression.
Safety and Handling
All tissues recovered meet stringent specifications related to donor screening and testing.
Each allograft is processed, sterilized and packaged with proprietary, device-like methods – to ensure consistent, high quality tissue for transplantation.
Simple Storage and Preparation
Ambio5 Allografts are provided dehydrated for room-temp storage. No freezing or refrigeration required. Ambio5 activates with sterile saline within minutes. No thawing or soaks required.
Human amniotic membrane is a unique, thin, collagenous membrane derived from the submucosa of the placenta, the area in which the human fetus grows and develops within the mother’s uterus. Human amniotic membrane consists of collagen layers including: (1) basement membrane; (2) stromal matrix.
Ambio5Allografts are comprised of native amniotic membrane tissue layers, including the basement membrane, stromal surface and additional, retained collagen from the placental interface. Each allograft is packaged in a double peel-pouch packaging configuration. Ambio5 allografts are thin, opaque and extremely lightweight.

All test results for serology, bacteriology and infectious diseases are reviewed prior to the release of the tissue. Only tissue from donors with acceptable test results, according to the standards of all state and federal regulatory bodies, are released.
To ensure a safe and compliant product is produced, the following criteria have been evaluated and are sufficient to indicate donor suitability:
• Infectious disease test results
• Consent documents
• Donor medical history & behavior risk assessment according to public health standards
• Information from other sources or records which may pertain to donor suitability:
· Physical assessment
· Available relevant medical records
· Tissue procurement test results
To ensure a safe and compliant product is produced, the above criteria have been evaluated and are sufficient to indicate donor suitability.
The names and addresses of the testing laboratories, the listing and interpretation of all required infectious disease tests, a listing of the documents reviewed as part of the relevant medical records, and the name of the person or establishment determining the suitability of this allograft are on file and available upon request.
This allograft has been determined to be suitable for transplantation.
Ambio5 should not be implanted into: (1) areas with active or latent infection; and/or (2) into a patient with a disorder that would create an unacceptable risk of post-operative complications.
Preparation, Reconstitution and Surgical Use
Prior to surgery, carefully follow the Ambio5 allograft preparation steps below with aseptic technique:
- The outer peel pouch is NOT considered sterile. The inner pouch, which contains the allograft, is considered sterile (unless the pouches are damaged or compromised).
- Carefully open the peelable corner of the outer pouch and present the inner pouch onto the sterile field. Ensure that the inner pouch does not come in contact with any portions of nonsterile surface of the outer pouch.
- Ambio5 allografts are packaged with the stromal matrix side down to or in contact with the metallic side of the pouch. The basement membrane side is packaged FACE UP or away from the metallic side of the pouch.
- Visual identification of the BASEMENT MEMBRANE side of Ambio5 can be noted by the correct horizontal orientation of the “IOP” lettering embossed on the center of the graft.
- In the sterile field, SLOWLY peel a corner of the inner peel pouch and allow the surgeon to grasp the allograft with fingers or non-toothed, sterile forceps. PLEASE TAKE GREAT CARE WHEN REMOVING THE ALLOGRAFT FROM THE INTERNAL POUCH. THE ALLOGRAFT IS THIN AND EXTREMELY LIGHTWEIGHT.
- In its dry state and prior to hydration, the surgeon may cut the allograft with sharp scissors to the appropriate and approximate sized required.
- The allograft should then be place on the surgical site. Clinical literature suggests that the stromal side should be in contact with the surgical site; the basement side should face away from the surgical site.
- The allograft can then be hydrated while on the surgical site with sterile saline solution. Simply apply several drops of sterile solution to the allograft at one to two minute intervals for a period of 5 to 10 minutes. During and following hydration, the “IOP” embossment on the allograft will begin to fade. It may take several minutes for the embossment to completely fade.
- Following the recommended hydration period, the surgeon should monitor the effect of hydration by visual inspection and while manipulating the allograft. Some allografts may take slightly longer to hydrate.
- Absorbable, non-absorbable suture material and/or tissue adhesives can be used to fixate Ambio5 allografts to the surgical site.
Ambio5 allografts should be stored in a clean, dry environment at controlled room temperature of 0º to 38º C (32º to 100º F).
Allograft Processing, Preservation and Sterilization
Ambio5 allografts are processed, dehydrated and sterilized based upon strict, quality-controlled protocols. Each allograft is thoroughly cleaned using a process that leaves no deleterious residue. An additional assurance of safety is achieved by terminally sterilizing each allograft. Based upon validations, each graft has been effectively sterilized without causing adverse effects to the biomechanical properties of the collagen. Ambio5 allografts are processed with Streptomycin Sulfate and Gentamicin Sulfate.
The FDA requires that recipient records be maintained for the purpose of tracing the allograft following surgical transplantation. The surgeon or operating staff member must complete the enclosed Allograft Utilization Record, attach a peel-off, allograft-tracking label provided, and mail to the distributor (postage-paid). Please use the remaining peel-off, allograft-tracking labels for patient and hospital records.
Caution: Federal law (U.S.A.) restricts this unit to sale by or on the order of a physician.
