Correlation of the MCR with the included angle between wires along the long axis of an FD stent. This stent was made of 48 wires (N) with a wire diameter of 0.04 mm (d) and a wire spiraling a complete turn length of 14.2 mm (B). When the included angle (α) is 90°, the MCR decreases to a minimum of approximately 20%. When the included angle is <30° (eg, the stent is stretched in the microcatheter) or >150° (eg, the stent is compressed at the neck), the MCR sharply increases.
