200 33 group t 300 100 group p and 200 20 group x based on a model fit of the radial strength data to the re and ae the was a good correlation r 2 0 89 between the radial strength and the re and ae radial strength increases with an increase in radial expansion and axial elongation group p 300 200 has the highest radial strength and group f 500 200 is the second highest having a slightly lower value within the margin of error the data demonstrates the synergy of the radial expansion axial elongation for example group b has the same re 500 and a lower ae 20 compared to group f however the larger ae of group f results in a higher radial strength in addition there is an unexpected lack of correlation between the hoop strength of a deformed tube and the radial strength of the corresponding stent for example the group f 500 200 deformed tube has the highest ultimate strength in the hoop direction with the group p 300 100 deformed tube having an ultimate strength well below the group f tube however as stated above the group p stent has a radial strength above the group f stent fig1 depicts a bar chart with a comparison of the diameter at deployment to fracture of stents made from tubes with re ae of 500 20 group b 400 20 group g 500 200 group f 200 33 group t 300 100 group p and 200 50 group x the 500.
