Beschreibung
Zusammenfassung:	The invention is directed to an endovascular device having an undulating pattern of struts and loops, where at least one strut has a bend in the crimped profile for reducing the compressed diameter. The strut configuration comprises one or more bent sections facing in opposite convex and concave orientations, thereby creating a space or hollow for an oppositely aligned portion of the device to nestle therein as the device is compressed. The undulating pattern may be staggered such that adjacent loops in the helical direction are axially offset with respect to a perpendicular axis perpendicular to the lengthwise direction, where a loop may be positioned to align with an adjacent strut in the helical direction. The device may include struts of varying lengths which may contribute to an enlarged expanded diameter of the device. The bent strut design of the crimped profile may be used with any endovascular strut design.
