ElectroForce® Stent/Graft
t Test Instruments for Pulsatile Distention
Accelerated Performance
t
to Reduce
tt Testing Time
Ten year FDA in vitro tests take only weeks with
ElectroForce® stent/graft test instruments. Using
Bose® proprietary high-bandwidth, low distortion
linear actuators, the instruments reduce test time
and provide multi-billion cycle reliability. The
ElectroForce stent/graft test instrument verifies the
fatigue life of intravascular prostheses such as stents,
grafts, heart valve frames, occluders and shunts
under simulated physiological displacements. The
instruments are designed to provide automated
control for long-term, 400-600 million cycle tests.
The proprietary dual pulsatile power head provides
uniform pulsatile distention at accelerated test
frequencies. The system is capable of achieving
mock vessel diametric distention that is equivalent
to a test-to-success requirement, or, the system may
be used to achieve greater than in vivo conditions
for a fatigue-to-fracture test. This allows developers
to evaluate the fatigue life of a device design under a
variety of programmed loading conditions.
