摘要： A stent for expanding a lumen of a body having a structural stability along the length of the stent, as well as a good expandable force. According to one embodiment of the present invention, the stent is made of a single length of a filament and includes zigzag sections, in which the filament is wound in a zigzag manner, disposed on both end portions of the stent; and a spiral section, in which the filament is wound in a spiral manner, disposed between the zigzag sections. The zigzag section includes a plurality of bands. Each of the bands includes a series of straight portions, peak portions, and valley portions, the peak and valley portions being integrally engaged with the straight portions, and each of the bands is disposed along a circumferential direction of the stent on a plane substantially perpendicular to a longitudinal axis thereof; and each valley portion of the bands is twisted with a peak portion of an adjacent band. Also, the spiral section includes a body portion formed in such a way that the filament crosses in a spiral pattern to form a plurality of segments with the filament being not engaged with each other, and upper and lower end portions having a plurality of bent points.
