    • A helical stent having a central helically wound portion, and cylindrical ends is provided. A transition zone having struts of different lengths is provided between the helical portion and each cylindrical portion. A junction defining a strut trident is provided between the transition zone and the helical portion. This construction provides a highly flexible stent, permits connecting bridges that are in the same basic orientation, and enables the hoops of the helical, cylindrical, and transitions zones to remain “in phase” such that the stent can easily expand and collapse. According to another aspect of the invention, the kerf between adjacent struts does not go all the way to the end of those struts. The longer struts can have substantially the same flexibility and expansion force as the shorter struts of the transition by making all the kerfs approximately the same length.
    • 提供了具有中心螺旋形缠绕部分和圆柱形端部的螺旋支架。 具有不同长度的支柱的过渡区域设置在螺旋部分和每个圆柱形部分之间。 在过渡区域和螺旋部分之间设置了一个定义支柱三叉戟的连接点。 这种结构提供了一种高度灵活的支架,允许连接相同基本​​方向的桥梁,并且使得螺旋,圆柱形和过渡区域的环能保持“同相”,使得支架容易膨胀和折叠。 根据本发明的另一方面,相邻支柱之间的切口并不一直到那些支柱的末端。 通过使所有切口大致相同的长度,较长的支柱可以具有与过渡的较短支柱基本上相同的柔性和膨胀力。

    • Method and Tooling for removing material from holes or orifices (round or other shapes) or the like in a workpiece, the method and tooling providing means for directing at least a first portion of an abrasive flow composition under pressure from a main body of composition from one side of a workpiece to another side of the workpiece (i.e. about the workpiece) so as to permit at least a second portion of the abrasive flow composition also under pressure from the same main body of composition to easily flow through the holes therein. In the preferred embodiment a first portion of the composition which is directed about the workpiece is returned to a point adjacent another side of the workpiece and is directed at an angle to the flow of the second portion of the composition through the holes in order to produce an interaction between the flow of said first and second portions of said composition.
    • 用于从工件中的孔或孔(圆形或其他形状)等中去除材料的方法和模具,所述方法和模具提供装置用于在来自组合物主体的压力下引导磨料流组合物的至少第一部分 工件的一侧到工件的另一侧(即,围绕工件),从而允许至少第二部分的磨料流组合物在相同的主要组合物的压力下容易地流过其中的孔。 在优选实施例中,围绕工件引导的组合物的第一部分返回到与工件的另一侧相邻的点,并且通过该孔与组合物的第二部分的流动成一定角度,以产生 所述组合物的所述第一和第二部分的流动之间的相互作用。
