Advanced Placental-Based Allografts When Patients Are in Need

Providing Protective Barriers and Environments that Support the Healing Cascade

There are many risk-factors to healing such as patient co-morbidities and complex defects.1 MIMEDX offers an array of advanced placental-based allografts that may be used in a variety of surgical applications to provide valuable benefits in patient care. 


    • Provide a protective barrier and environment that supports the healing cascade
    • Protect the wound bed to aid in the development of granulation tissue
    • Provide a human biocompatible extracellular matrix (ECM) and contain 250+ regulatory proteins 2-5


      • A lyophilized, biocompatible, and human extracellular matrix derived from the placental disc.
      • For use in the replacement or supplementation of damaged or inadequate integumental tissue.
      • Versatile and easy to use: apply dry or hydrated as a paste.
      • Early scientific data in a nude mouse model shows AXIOFILL supports site appropriate function in tissue by allowing cell attachment, new collagen formation on the matrix, and new blood vessel formation.6

      Clinical Use Examples:

        • Debridement/ Dehiscence
        • Complex soft tissue defects
        • Complex incision management
        • STSG
        • Low anterior resection
        • Colostomy reversal
        • Fistula repair
        • Amputations

        How Physicians Use Our Products

        Case study 1

        Acute Abdominal Wall Dehiscence with EPIFIX7


        A 62-year-old obese male, BMI of 29, type II diabetes, with a history of hypertension, myocardial infarction with stent placements, multiple abdominal surgeries, and over 40 years of cigarette smoking, underwent large ventral hernia repair. At one week post-op, the patient developed ischemia at the incision line, which led to an incisional dehiscence.

        Studies have shown a direct correlation between the number of comorbidities and clinical outcomes. A significant rise in complications, length of stay, and mortality rates is associated with the rise in number of patient comorbidities.8-10

        Surgical Intervention

        The patient was managed with serial debridement and wet-to-dry dressings for two months, then placed on negative pressure wound therapy (NPWT) for four weeks at home. After one month of NPWT, the wound had only decreased by 30%. NPWT was discontinued, and EPIFIX was applied every other week, instead of weekly, due to the travel distance for the patient.


        Upon examination at his two month EPIFIX follow-up visit, the wound was fully closed and re-epithelialized. The patient returned for a routine one-year visit and has remained fully closed and asymptomatic.

        Following Debridement Four weeks of NPWT, only 30% size reduction, first EPIFIX 4 cm x 4 cm applied Week 2: Two 2 cm x
        3 cm EPIFIX applied
        Week 4: One 2 cm x
        3 cm EPIFIX applied
        Week 8: Wound closed and stable

        Case study 2

        Colostomy Reversal with AMNIOFIX11


        A 68-year-old male underwent an emergency Hartmann’s procedure with a rectosigmoidectomy and end colostomy with a rectal pouch, due to a perforation of the sigmoid colon from acute diverticulitis. Though wound healing in elderly people is not necessarily impaired, age-related changes are evident. Comorbidities, which are associated with impaired healing, are more prevalent in older patient populations and can delay healing by 20-60%.12 Anastomotic leakage is the most common and much-feared intraoperative complication in colostomy reversal.13,14 One study showed the anastomotic leakage rate at as high as 3.8%.15 In addition to anastomotic leakage, other common postoperative complications include wound infection, incisional hernia, ileus, and enteric fistula formation.13,14

        Surgical Intervention

        Five months later, when the patient’s overall condition improved, a colostomy reversal using a single-port laparoscopic technique with AMNIOFIX was performed. A 2 cm x 6 cm AMNIOFIX graft was placed laparoscopically on the colorectal anastomotic stapled site and was stitched into place with absorbable sutures.


        The patient was seen two weeks after the surgery with no postoperative complications. The patient was having normal bowel movements daily.
