Torsion Testing

Medical device often experience torsion during use. For example, medical bone screws experience torsional loading during the implantation; devices for intravascular applications experience torsional loading post implantation, stent-grafts used in peripheral indications experience torsion due to normal limb motion, devices for aortic repair experience torsional loading due to twisting of the torso, surgical tools experience rotational forces during use. Torsion testing is conducted to evaluate the real-world performance of medical device that undergo rotational motion when in service.

STEMart can design and conduct suitable torsion testing for many different types of medical devices.
