Material Selection

While the benefits of placental-derived allografts are well documented1,2, human-derived grafts can be extremely variable due to the unique medical histories and social behaviors of each donor5-12. Knowing this challenge, a porcine source was selected because it can be controlled for age, diet, health, and activity level, thereby greatly reducing the variability of the raw material used to manufacture InnovaMatrix® AC.

The TriCleanse Process balances the need for decellularization while maintaining structural proteins of the ECM.3,4,16,17

A Critical Balance

Effective decellularization removes cells and cellular debris while maintaining the structural proteins of the ECM18.

A Critical Balance

Effective decellularization removes cells and cellular debris while maintaining the structural proteins of the ECM11.

The presence of cells and or cellular debris in biologic wound dressings can cause an inflammatory reaction resulting in a greater M1:M2 ratio macrophage response by the host immune system at the wound site. Thoroughly decellularized biologic skin scaffolds allow the host to react directly with a healing response, generally associated with a greater M2:M1 ratio of macrophages and leading to collagen deposition19,20.

Balancing Decellularization Efficiency and the Denaturing of ECM Proteins

As a placental medical device processed with the proprietary TriCleanse™ Process, InnovaMatrix® AC was extensively biochemically characterized to identify and quantify the different structural and functional proteins. These results were then compared to an SIS membrane device as a base line for comparison.

Cellular Debris Comparison4

The presence of intact cells and nuclei creates an immunogenic response as cellular antigens are recognized as foreign by the host’s immune system.

The immune system has the innate capability to recognize nucleic acids not contained within the nucleus via pattern recognition receptors and mount an inflammatory response to their presence.

Hematoxylin and Eosin Staining4

Hematoxylin and Eosin (H&E) staining is commonly used to stain tissue for histology evaluation21. H&E stains nuclei blue and extracellular matrix and cytoplasm pink and other tissues shades in between.


The H&E staining shows a minute quantity of residual nuclei in the finished product.

SIS Commercial Membrane

The H&E staining shows clearly stained blue nuclei are distributed throughout the finished product.

HCT/P Commercial Graft

The H&E staining shows blue stained nuclei present in the entirety of the graft with areas of high concentration.

First-ever placental-derived medical device cleared by the FDA for wound management

Summary of Indications, Contraindications, and Warnings

InnovaMatrix® AC is indicated for the management of wounds including:

  • Partial and full-thickness wounds
  • Pressure ulcers
  • Venous ulcers
  • Diabetic ulcers
