Mechanical Properties of Nitinol Stents and Stent-grafts
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
