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.

The present invention is directed to a method of securing suture within a patient. The method comprises advancing suture material into the patient, passing a portion of the suture material through tissue of the patient, and advancing a fastener catheter and a suture fastener along the suture material. The fastener catheter includes a catheter main body and a handle. The suture fastener has a generally cylindrical body formed of a shape memory material and a suture fastener inner lumen. The suture fastener has at least one engagement tab biased to extend at least partially into the suture fastener inner lumen to engage against and secure one or more lines of suture passing through the suture fastener.

A device for holding flatware which flatware is cleaned in a commercial warewashing machine is disclosed. The device is secured to a conventional dolly. A drive wheel on the device engages the conveyor pan. As the dolly moves, the drive wheel oscillates a frame about a fixed axis. The frame carries the baskets which loosely hold the flatware. As the dolly moves the flatware is tossed to and fro eliminating nesting to ensure all surfaces are contacted by the wash water.

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.

A horizontally sliding seal tight door is provided for a warewasher. The leading and trailing edges of the door are formed to mate with guide members secured to the sides of the door opening. When in the closed position the edges of the door in combination with the guide members direct the water contacting the door into the warewasher.
摘要:
A scraper nozzle which provides a high pressure, uniform sheet of water. The nozzle is preferably used in the upstream portion of the prewash zone of a warewasher. Wares, such as dishes, are contacted by the sheet of water and the materials on the dishes are scraped off. The nozzle comprises a planar surface and an arcuate surface. The arcuate surface terminates in a discharge edge which is characterized by a plurality of protuberances. The water flows across the discharge edge and forms the uniform sheet of water.
