摘要: A coiled-sheet stent includes a tubular body having longitudinal axis and circumference, plurality of cylindrical bands formed in the body, each band zig-zag pattern including series sequential diagonal elements connected to one another extending about circumference. connectors extend between connect adjacent bands. The have an arcuate shape, all being oriented either clockwise or counter-clockwise direction is expandable contracted enlarged conditions, unstretched biased towards stretched condition above transition temperature, thereby at least partially defining condition. multi-cellular structure also provided that bat shaped cells cell head region, tail region opposing curved wing regions, connecting cells. regions are directly another,
