Service Overview
Testing for biological material properties, medical device quality, and system performance are important for design and development. We offer biomaterial testing services for bones, joints, muscles, tendons, and ligaments to determine properties such as material strength, stress/strain, micromotion, and failure characteristics. Mechanical properties are measured with our load frame apparatus. Micromovement between two rigid body segments may be measured using a highly accurate radiographic technique known as radiostereometric analysis (RSA). Medical device quality and performance may be tested in a physiological setting by replicating clinically relevant loads and cyclic conditions to cadaveric models.
Additional Information
What equipment do you use for testing?
Cadaveric specimens can be ordered in to our facility and stored in our preserving chamber. Test preparation and procedures are done safely in our biohazardous laboratory equipped with surgical instruments and a sterilization unit.
Tension, torsion, compression, and cyclic load testing is performed through our load frame testing machine. Testing can be customized to suit the needs of each individual test.
RSA testing is done in a radiological examination room housing our fully integrated RSA system.
Other equipment is acquired and utilized per the requirements of each test, such as; micrometers, LVDTs, and strain/force sensors.
Why is this type of testing important?
Biomaterial and biomechanical testing in cadaveric specimens will provide valuable quantitative data needed to determine device quality, performance, and survivorship through true physiological conditions. It may also provide supportive evidence required for pre-market approval of new devices.
