Catheter torque capability or torque efficiency describes a measure of rotational feedback at the distal end of the device while rotation is applied at the proximal end. Designed to meet the requirements of ISO 10555, ISO 25539, ASTM F2394, and FDA guidance documents for catheters or guidewires, MSI's simulated use test equipment uses torque transducers to measure torque efficiency or rotational response in linear paths or simulated configurations.
Standard test methods include:
Torque Strength
Rotation response
Torque to failure
Rotational bond strength
