From decades of research, our proprietary CryoTek^® preservation process has been designed to maintain the native tissue than dehydration without the live cellular components to optimize safety and delivery. The result is an amniotic allograft that delivers:

• Convenient Storage – Our cryopreserved matrices can be safely stored in a standard refrigerator for up to 2 years.
• Preparation Efficiency – With no thawing requirements or complicated preparation procedures, BioTissue Surgical products are ready when you are.
• Operational Flexibility – The matrix remains stable even when left at room temperature for up to 6 hours and returned to storage – minimizing wastage.
• Superior Handling – With an unmatched thickness 10x thicker than amniotic membrane alone, our umbilical cord-based products simplify handling and surgical placement over thinner alternatives.
• This process yields a matrix that simplifies usage and storage without compromising its structural or functional integrity.
