摘要： There is disclosed herein a radially expansible stent formed from a tube, comprising a continuous spiral of tube material with a plurality of turns (30, 32) wrapping about a longitudinal axis from a first end of the stent to a second end of the stent, the spiral including a plurality of struts (40, 42) in a zig-zag arrangement joined at points of inflection (44), whereinreach strut includes a double bend (46) remote from a point of inflection (44) and first (58, 60) and second (62, 64) length portions on opposite sides of the double bend (46); adjacent struts (40, 42) have handed double bends that are substantially mirror images of one another, the handed double bends facing each other such that in a stent collapsed configuration the length portions (58, 60) of adjacent struts on a first side of the double bends (46) are spaced closer than the length portions (62, 64) of adjacent struts on a second side of the double bends (46) opposite the first side, the adjacent struts on said first side of the double bends being joined at a point of inflection (44); and each point of inflection (44) on said first side of the double bends (46) on one turn (30) of the continuous spiral lying between adjacent struts on said second side of the double bends (46) on the next turn (32) of the continuous spiral. A method of forming such a stent is also disclosed.

摘要： A stent (10) formed by slitting a tube to create a matrix of struts which are separated from each other by no more than the width of the slit and which lie more or less parallel to each other and to the longitudinal axis of the tube, the slitted tube being radially expandable to a stenting disposition in which the struts exhibit a zigzag pattern in successive loops around the circumference of the stent, the angle each strut makes with the longitudinal axis increasing as the stent diameter increases the zigzag pattern exhibiting a cusp between any two adjacent struts with selected tied cusps of any one loop being connected by a bridge (12) to a facing cusp of the adjacent loop, the bridge extending in a direction parallel to the longitudinal axis of the tube and with intervening free cusps (46, 48), between any two bridge of a loop, not being connected to the adjacent loop the zigzag pattern exhibiting a lengthwise staggering of circumferentially adjacent said slits to the extent that the lengths of two circumferentially adjacent struts on the zigzag pattern that flank a tied cusp are different and further such that, in the said stenting disposition, the free cusps of adjacent loops are circumferentially displaced from each other; and characterized in that: a majority of the struts in any one of the successive loops share a first common length X, and any remaining struts in said one loop share a second common length Y (42), wherein Y
