Sterile, Room Temperature Human Dermis Graft
Derm-Maxx™ Dermal Matrix is an acellular human dermis graft sterilized using the Tutoplast® Tissue Sterilization Process. This proprietary process retains the three dimensional intertwined multidirectional fibers and mechanical properties of the native tissue. Derm-Maxx™ Dermal Matrix provides a natural scaffold to support the body’s regenerative processes.
Derm-Maxx™ Dermal Matrix at a Glance
STERILE
BIOCOMPATIBLE
- Preserved vascular channels
- Preserved key components of the native matrix
- Revascularization evident in as early as 7 days in an animal model
CONVENIENT
- Five year shelf life
The Tutoplast Process uses solvent dehydration to allow for a five year on-the-shelf storage. This proprietary processing step eliminates the need for freezing or refrigeration of the graft. The storage characteristics of Derm-Maxx™ Dermal Matrix provide convenient, on-the-shelf storage between 1 °C and 37 °C for easy access and use.
- Simple single step rehydration
Derm-Maxx™ Dermal Matrix’s single rehydration step* in room temperature sterile saline requires minimal effort and time. The quick rehydration of the Derm-Maxx™ Dermal Matrix can reduce OR time and costs
TUTOPLAST PROCESS
Overall the structure, biomechanics and remodeling characteristics of the implant are maintained.
HOROUGHLY PENETRATES TISSUE
Osmotic treatments disrupt cell membranes to allow for full penetration of the graft.
VALIDATED VIRAL INACTIVATION
- Ability to inactivate or remove HIV, hepatitis, fungi, and spores
- Validated by individual tissue type based on most difficult case testing using most difficult to kill organisms
How does the Tutoplast® Process work?
Osmotic, oxidative and alkaline (if indicated) treatments break down cell walls, inactivate pathogens, and remove bacteria.
Solvent dehydration allows for room-temperature storage of tissue without damaging the native tissue structure.
Low-dose gamma irradiation ensures a sterility level (SAL) of 10-6 of the final packaged graft.
1. ALKALINE TREATMENT
Removes cells and lipids whichinterfere with healing.
2. OSMOTIC TREATMENT
Disrupts cell membranes to allow easierremoval of cellular components.
3. OXIDATIVE TREATMENT
Inactivates pathogens and removesbacteria.
4. SOLVET TREATMENT
Removes water from tissue, preserves the natural tissue matrix and allows for room-temperature storage without damaging the native structure.2. OSMOTIC TREATMENT
Disrupts cell membranes to allow easierremoval of cellular components.
Pre-Processed vs. Tutoplast Processed Human
Dermis
PRE-PROCESSED HUMAN DERMIS
Note presence of intact epidermis.
TUTOPLAST PROCESSED HUMAN DERMIS
Note epidermis has been removed and underlying matrix has been preserved.
PRE-PROCESSED HUMAN DERMIS
Note the presence of cellular debris throughout (purple cell nuclei).
TUTOPLAST PROCESSED HUMAN DERMIS
Note the absence of cellular debris and the intact tissue matrix.

BIOCOMPATIBILITY
The donated human tissue source of Derm-Maxx™ Dermal Matrix produces a biocompatible intact porous
scaffold to support cellular proliferation and revascularization. The Tutoplast Process preserves the key
components of the native matrix that support the body’s regenerative processes.
IN-VIVO ANIMAL MODEL STUDY*
The graft functioned successfully as a scaffold and is fully incorporated and remodeled by the host tissue.
DAY 1
Beginning of cellular infiltration of the graft by host tissue.
DAY 7
Vascularization evident, invasion of fibroblasts and other cells found in normal healing cascade of the graft by host tissue.
WEEK 8
Difficult to distinguish implant from host tissue; graft is well incorporated.
WEEK 16
Beginning of cellular infiltration of the graft by host tissue.
*Performance data from animal studies may not be representative of performance in humans.
