    摘要: A stent includes a continuous wave form wrapped around a longitudinal axis of the stent at a first pitch angle to define a first helix comprising a plurality of turns. The wave form includes a plurality of struts and a plurality of crowns. Each crown connects adjacent struts within a turn to define the continuous wave form. The stent also includes a plurality of connections configured to connect selected crowns of adjacent turns so that when the stent is in an unexpanded condition, the plurality of connections are aligned at a second pitch angle to define a second helix, and when the stent is in an expanded condition, at least some of the connections align along a substantially straight line parallel to the longitudinal axis of the stent.

    摘要: A stent includes a continuous wave form wrapped around a longitudinal axis of the stent at a pitch to define a helix comprising a plurality of turns. The wave form includes a plurality of struts and a plurality of crowns. Each crown connects adjacent struts within a turn to define the continuous wave form. The stent also includes a plurality of connections configured to connect selected crowns of adjacent turns. Unconnected crowns of adjacent turns that substantially face each other are spaced from each other and define a gap therebetween. The gap between the unconnected crowns of adjacent turns is variable around a circumference of the stent.

    摘要: A stent includes a wave form that includes a plurality of struts and a plurality of crowns. Each crown connects two adjacent struts within the wave form. The wave form is wrapped around a longitudinal axis at a pitch angle to define a plurality of turns and has a central portion and two end portions located on opposite sides of the central portion. At least some of the struts located in the end portions have lengths longer than an average length of all of the struts of the wave form. The stent also includes a plurality of connections. Each connection connects selected crowns from adjacent turns. The connections are positioned along the stent substantially equally so that a density of the number of connections of the end portions is substantially equal to a density of the number of connections of the central portion.

    摘要: A stent includes a wave form that includes a plurality of struts and a plurality of crowns. The wave form is wrapped around a longitudinal axis so as to define a plurality of turns, including a first turn disposed at a first angle and a second turn disposed at a second angle relative to the longitudinal axis. A first connection connects an end of the wave form that started the first turn to an adjacent crown of the wave form that completed the first turn, a second connection connects a first crown of the second turn to an adjacent crown that completed the second turn, and a third connection connects a crown of the first turn to an adjacent crown of the second turn. The wave form is disrupted between the first turn and the second turn.

    摘要: An apparatus for forming a wave form for a stent from a wire includes a pair of tension wires configured to rotate about an axis. The tension wires and axis are substantially orthogonal to the stent wire disposed in a gap between the tension wires. When the tension wires are rotated, a bend is formed in the portion of the stent wire disposed between the tension wires. The tension wires may be controlled such that the axis of rotation is aligned with the particular tension wire around which the stent wire is to be bent for each particular bend formed in the stent wire, thereby preventing the particular tension wire from translating during rotation such that the tension wire behaves like a rotary pipe bending die around which the stent wire is bent. A feed assembly feeds the stent wire into the forming area between the tension wires.
