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.
