STENT SECUREMENT TESTING SR1000-2SR1000 Stent Securement Testing Equipment

The SR1000 Stent Securement Testing Equipment is designed to measure and record the force required to dislodge a balloon-expandable stent from its proper position on a balloon. The SR1000 is comprised of a multi-sectioned segmental head, including one segment that radially grips the balloon and another segment that captures the stent edge. These head sections separate to dislodge the stent proximally or distally from the balloon. The SR1000 utilizes stepper motor linear actuators for precise diameter control and smooth pull action. Test results can be used for regulatory submissions, competitive product testing, R&D device evaluation and inline manufacturing quality assurance. MSI designed the stent securement tester to work as a standalone unit with an optional submersible configuration for testing in an aqueous, temperature-controlled environment. The system can also be purchased as an add-on to the MSI Interventional Device Testing Equipment (IDTE2000).
