  • Patent number: 10737370
    Abstract: Adjustable-size jaw sub-assemblies, jaw assemblies made from such sub-assemblies, and tools, particularly hand tools, made using such jaw assemblies. A plurality of jaws are connected to a base ring by pivot pins. Cam follower recess can be defined at positions of the inner perimeter of the base ring, and between opposing faces of the base ring. In the jaw assemblies, an actuator, such as a cover plate, covers at least a portion of one of opposing faces of the base ring, and one or more bridges connect the jaws to the actuator. Movement of the base ring relative to the actuator causes the jaws to pivot about the pivot pin axes, with the jaws moving in concert with each other thereby to reduce or expand the size of a work opening defined by the jaws.

  • Patent number: 8869583
    Abstract: An apparatus and method for swaging a square or rectangular tube, the apparatus including a support for external dies, both surface dies and corner dies, which when actuated, apply pressure to the outside of a tube to achieve its swaging to a lesser dimension, and having a collapsible mandrel located therein, supporting internal dies, that apply a lesser pressure against the interior of the tube, during a swaging operation, to assure that wall buckling does not occur. An internal die with its removing tool may locate within the end of the tube to be swaged to cooperate with the pressure from the external dies to swage the tube without any final buckling.

  • Publication number: 20140259597
    Abstract: A pipe processing tool that is configured to deform the end of a pipe so that the circumferential shape of the end of the pipe generally matches the circumferential shape of an adjacent pipe end. Matching the circumferential shapes of the pipe ends is advantageous during a pipe attachment process. The pipe processing tool can include a deformation ring with a plurality of pipe deformation members. Each pipe deformation member faces radially inward and is actuatable in a radial direction toward and away from the center of the deformation ring in order to permit engagement with the pipe. Each pipe deformation member is individually and separately actuatable from the other pipe deformation members so that the circumferential shapes of the pipes can be altered by controlling suitable ones of the pipe deformation members.

  • Patent number: 8752261
    Abstract: A system for mounting a stent on a balloon catheter includes two positioning and alignment stations, which are used to prepare a stent and catheter for crimping using the same crimping head. The system is configured for automated assembly of the stent and catheter prior to crimping. A catheter and stent are placed on a computer-controlled carriage that delivers the stent and catheter to the crimper head. Before placing the stent and catheter into the crimper head, an automated alignment system locates the stent between balloon markers.

  • Patent number: 8667668
    Abstract: A method of sheathing a stent including the steps of providing a stent assembly including a catheter member and a stent member disposed about the catheter member; placing a first sheath film adjacent one side of the stent assembly; placing a second sheath film adjacent an opposite side of the stent assembly, and compressing the stent assembly, whereby the first and second sheath films move toward each other and substantially surround the stent assembly. The first and second sheath films are provided in rolls. Compressing is implemented by a radial compression mechanism. The first and second sheath films pass through the radial compression mechanism. Compressing sheaths the stent assembly and crimps the stent onto the catheter. As an alternative to two sheath films, a single film may be used, whereby compressing surrounds the stent assembly with the single sheath film. Also disclosed is an apparatus for sheathing a stent.

  • Patent number: 8652145
    Abstract: An exemplary system for crimping a prosthetic valve comprises a radially expandable and compressible prosthetic valve, a crimping device positioned around the valve and configured to reduce the diameter of the valve to a delivery configuration, and a sterile package enclosing the valve and the crimping device. The valve can be pre-assembled in a partially crimped configuration within the crimping device. After removing the sterile packaging, the crimping device can be used to crimp the valve from the partially crimped configuration to the delivery configuration, such as by twisting a knob on the crimping device. The system can further comprise at least a portion of a delivery catheter within the sterile package, wherein the valve is pre-mounted on or adjacent to an inflatable balloon of the delivery catheter, such that the valve can be crimped onto the delivery catheter using the crimping device.
