摘要： Preferred embodiments of a stent with a high degree of flexibility are shown and described. The stent can include a continuous helical winding having interconnected struts joined at vertices, and having bridges connecting sections of the helical winding to each other. An annular ring can be provided at one or both ends of the helical winding, and the annular ring can have extensions extending to connect to the helical winding. One of the extensions can connect to a bridge and another extension can connect to a vertex. The struts at the ends of the helical winding can have strut lengths that differ from the strut lengths of the struts in a central portion of the winding between the ends of the winding.

摘要： Preferred embodiments of a stent with a high degree of flexibility are shown and described. The stent can include a continuous helical winding and at least one bridge. The continuous helical winding has a plurality of circumferential sections that circumscribe a longitudinal axis from a first end to a second end to define a tube. The circumferential sections are spaced apart along the axis. The at least one bridge is configured to connect one circumferential section to an axially-spaced adjacent circumferential section. The at least one bridge extends on a plane generally orthogonal with respect to the axis.

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： An investment cast bronze end effector blade for a disposable laparoscopic surgical instrument having a push rod is disclosed. The end effector blade has an aperture for engaging either the push rod or a connecting staple which couples the push rod of the instrument to the end effector blade. The end effector blade has a body member having a sharp edge element and a base element integral with integral first and second masses of bronze. The base element is an extended portion substantially parallel to and in an offset configuration with the sharp edge portion, and includes an aperture to which the push rod or connecting staple couples. The first mass of bronze integral with the investment cast end effector blade bridges the offset configuration between the sharp edge element and the base element. The second mass of bronze integral with the investment cast blade partially surrounds the aperture of the base element and extends to the end of the base element remote from the sharp edge portion.

摘要： A Verres-type needle which has a sharpened outer needle and allows passage of a blunt inner needle within the outer needle. The Verress needle also contains a position indicator to indicate the position of the inner needle within the outer needle, so that the user knows whether the inner needle is in a protective or non-protective position. Further, a liquid level indicator demonstrates the path of liquid flow within the Verress-type needle. Finally, there is an acoustical enhancment mechanism, which allows the user to know whether the blunt inner needle has sprung forward within the abdominal cavity, to its most forward, protective position.

摘要： An actuator for a laparoscopic surgical instrument imparts reciprocal motion to a push rod surrounded by a hollow tube. The actuator includes a plastic housing which fixedly engages the hollow tube, and a lever which fixedly engages the push rod and pivotally engages the housing. The housing also preferably includes an integral handle. When the handle and lever are manipulated by the user such as by pivotal movement of the lever, reciprocal motion is imparted to the push rod relative to the hollow tube. The lever also includes an external unevenly surfaced portion which when frictionally engaged by a digit of a human hand will impart pivotal motion to the lever, and hence reciprocal motion to the push rod.
