Radial resistive force (RRF) is a fundamental performance parameter for vascular stents, describing the resistance a stent provides against external compression. Together with chronic outward force (COF), RRF defines the balance between vessel support and flexibility, directly influencing clinical outcomes such as vessel patency, restenosis rates, and patient comfort. Accurate measurement of RRF ensures that stents maintain lumen integrity without overloading the vessel wall.

At our testing facility, we provide comprehensive RRF evaluation services in accordance with ASTM F3067: Standard Guide for Radial Loading of Balloon Expandable and Self-Expanding Vascular Stents, supporting both innovation and regulatory compliance:

Chronic outward force (COF) is a critical performance parameter for self-expanding stents. It describes the sustained radial pressure exerted by the stent against the vessel wall over time, directly influencing vessel patency, tissue response, and long-term clinical outcomes. Accurate measurement of COF is essential to balance mechanical support with biological compatibility, ensuring that stents provide reliable function without excessive vessel trauma.
