RX550/650 stent radial force testing equipment
(more…) The RX550/650 is stent radial force testing equipment designed to measure and record radial stiffness and strength, chronic outward force during expansion and radial reactive force during compression of interventional devices such as; balloon expandable stents, self-expanding stents, stent grafts, collagen plugs, embolic filters, vena cava filters, and other radial expanding devices. The MSI RX550/650 stent radial force testing equipment facilitates knowledgeable and rapid device design changes by utilizing an integrated high speed data acquisition system and proprietary software to generate repeatable and reproducible data. At the core of the RX equipment is MSI’s proprietary segmental compression mechanism which collects data from twelve product contact points providing uniform radial measurement. The RX equipment utilizes an encoder for diameter accuracy, a linear actuator for activation and a precision roller bearing system that is specifically designed to provide a low friction testing environment. Test results can be used for regulatory submissions, competitive product testing, R&D device evaluation and inline manufacturing quality assurance.
