Tissue Processing


GraftCleanse™ Tissue Cleansing

The GraftShield™ process requires aseptic handling of all tissue throughout processing and is based on a scientifically validated sterilization method which results in a Sterility Assurance Level (SAL) of 10-6 in accordance with ISO 11137-2 Method 1. This validated process is designed to protect the biomechanical properties of each allograft while virtually eliminating patient risk.During processing, tissues are treated with the GraftCleanse™ process which includes chemical and physical cleaning procedures that reduce the bone marrow and lipid elements associated with normal human tissue.
