ASTM F2079 and F2477 Stents, Tensile Strength Testing
Radial testing of stents and other interventional devices is critical to their development as radial compression and expansion best simulate the contraction of these vessels as blood is pumped through the body. We partnered with Machine Solutions Incorporated (MSI), an innovative manufacturer of proprietary mechanical solutions for the medical device industry, to provide a radial testing solution that is compatible with our 5900 series universal testing systems.
The RX575 System is typically used for smaller devices like balloon expandable stents, self-expanding stents, collagen plugs, embolic filters and other basket type filter products. The RX675 System can be utilized for larger devices like stent grafts, vena cava filters or other radially expanding products. Test results can be useful for regulatory submissions, pre-clinical trial testing, competitive product testing and product design. As an option, either system can be configured with a temperature chamber to simulate physiological conditions.
5900 Universal Testing Systems are engineered for precision, built for durability, and offer the flexibility for changing requirements. They are designed with standard and optional features that increase testing efficiency and improve the testing experience for the operator. A wide range of models are available for testing capacities from < 100N up to 600kN.

The Instron RX Systems are the result of a partnership between Instron, a leading provider of equipment that evaluates mechanical properties of materials and components and Machine Solutions Incorporated (MSI), an innovative manufacturer of proprietary mechanical solutions for the medical device industry. At the core of the Instron RX Systems are Instron’s 5900 Series universal test frame and MSI’s proprietary segmental compression mechanism. The system can be used to generate standard tensile, compression, flexure, peel data, as well as radial stiffness and radial strength from 12 points of contact with the RX fixture. This data is a critical measurement during expansion and compression of interventional devices.
