摘要： A stent includes a central portion of helically wound undulations formed of struts, cylindrical end portions, and transition zones between the helical portion and the cylindrical portions. According to a first aspect of the invention, the torsional flexibility of the stent is maximized by having bridges connecting adjacent winding be interrupted by the maximum possible number of undulations. In a preferred design, each winding includes nineteen undulations around the circumference, bridges are provided every five undulations. According to a second aspect of the invention, uniform opening of the transition zone is achieved by altering the width, and thereby the flexibility, of a series of struts in accordance with their lengths. Specifically, the long transition zone struts are made wider.

摘要： 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.
摘要翻译： 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。

摘要： A surgical clip has a base portion and two generally parallel, spaced arms extending from the base portion and defining an opening therebetween. The arms terminate distally in fingers which are of reduced width and thickness relative to the arms and which are adapted to be bent towards and past each other. A transition section from each arm to the finger provides curved structures which extending away from each other and providing a wider mouth for the opening between the arms. The arms also have a proximal section with an undercut which helps in flexure of the arms. The base is an extended structure having a rounded proximal end with outwardly extending shoulders which are arranged to be engaged by the curved structures of the mouth of another clip.

摘要： Radioactive therapeutic seeds include a carrier structure bearing a radioactive isotope and a radiopaque marker. According to several embodiments, the seeds include a central plug provided with an axial marker and a relatively transverse bore extending through the marker. A second marker may be positioned in the bore, thereby distinguishing a seed provided with the second marker relative to a seed not provided with the second marker. According to another embodiment, the isotope is deposited on the outer surface of a hollow radiolucent tube. A biologically-compatible, radiolucent, surface-sealing layer seals the external surface of the tube. A radiopaque marker wire of selected length is positioned in the hollow of the tube. Seeds may be distinguished from one another by providing seeds with marker wires of different lengths. According to other embodiments, the seed includes a cylindrical outer member, and an inner member provided within the outer member and having two large diameter portions and a relatively smaller diameter portion therebetween. A marker is disposed within the inner member, and a radioactive isotope is carried on the inner member. The marker may be drilled to a smaller size. Each embodiment permits at least two groups of seeds to be distinguished from one another by the use of differing marker configurations.
