Each stent was situated between two flat plates (2" wide) attached to the INSTRON® Tester and the plates were advanced toward each other (Figure 5). The force required to compress the stent radially by 25% (1.5 mm) was measured. Results To test radial compressive strength, all stents were placed between two flat plates
Fatigue Testing Stent Materials and Structures. Traditional testing of stent and stent grafts (to standards such as ASTM F2477) involves subjecting complete devices to pressure pulsation simulating blood flow for a pre-specified number of cycles. Even if the device has not fractured, a simple pass/fail criterion is used for the test to succeed.
