ElectroForce® Stent/Graft Test Instruments Using the patented high-bandwidth, low distortion Bose® linear actuator, the ElectroForce Stent/Graft test (SGT) instruments accelerate stent testing and provide multi-billion cycle reliability. SGTs increase crucial speed to market and test more devices simultaneously. The SGT verifies the fatigue life of vascular prostheses such as coronary and peripheral stents and thoracic and abdominal endovascular grafts under simulated physiological loading conditions. Bose has developed the ElectroForce® 9400 Multi-axis Peripheral Stent (MAPS) test instrument for stent applications in peripheral arteries. This programmable instrument simulates the complex loading that stents experience in the peripheral arteries. These include the renal arteries, the carotid arteries, and the femoral-popliteal arteries. This system is capable of combining dynamic bending, rotation, extension/compression, and radial distention on multiple stents under controlled conditions. Bose Corporation has developed the ElectroForce® 9500 multiaxial coronary stent (MACS) test instrument to simulate the combinations of deflections and displacements that vascular stents experience after deployment into coronary arteries. The 9500 instrument is capable of simulating multiple axes of motion to provide a better representation of in vivo conditions for fatigue and durability evaluation. The system can combine dynamic bending, rotation, extension, and pulsatile distension on up to twelve (12) stents under controlled conditions.
