  • Patent number: 10376922
    Abstract: The disclosure features material separators for screening excavated material (e.g., rocks from soil.) In some implementations the materials separators include (a) a supporting frame; (b) a screening surface mounted at an incline on the supporting frame, the screening surface comprising a plurality of fixed bars that are attached to the frame in a manner to resist upward movement, and a plurality of shift bars that are attached to the frame at their upper and lower ends, in a manner to allow upward movement; and (c) a shift bar actuator, positioned between the upper and lower ends of the shift bars, the shift bar actuator being configured to impart a two-stage movement to the shift bars, whereby during a first stage the upper ends are first displaced vertically, and during a second stage the lower ends pivot upward about the upper ends.

  • Patent number: 9883957
    Abstract: A luminal prosthesis comprises a plurality of radially expandable prosthetic stent segments arranged axially. Two or more of the prosthetic stent segments are separable upon expansion from the remaining prosthetic stent segments and a coupling structure connects at least some of the adjacent prosthetic stent segments to each other. The coupling structure permits a first group of the adjacent prosthetic stent segments to separate from a second group of the prosthetic stent segments upon differential radial expansion of the first group relative to the second group and the coupling structure maintains or forms an attachment between the adjacent prosthetic stent segments in the first group which have been expanded together. A delivery system and methods for deploying the multiple coupled prosthetic stent segments are also disclosed.

  • Patent number: 9198784
    Abstract: Apparatus for delivering stents to body lumens include one or more tubular prostheses carried at the distal end of a catheter shaft, a sheath slidably disposed over the prostheses, and a guidewire tube extending from within the sheath to the exterior of the sheath through an exit port in a sidewall thereof. A guidewire extends slidably through the guidewire tube. The sheath can be moved relative to the catheter shaft and the guidewire tube to expose the prostheses for deployment. Methods of delivering stents are also provided.

  • Patent number: 8756941
    Abstract: A cryogenic apparatus is provided having a nested thermally insulating structure, thermal links, a vacuum shroud, and a cryo-cooler. The nested thermally insulated structure holds a sample to be cooled while dampening the external vibrations caused by the cryo-cooler, the surrounding environment or cryo-cooler mounting surface. The thermal link is made of thermally conductive wires which connect the nested thermally insulated structure and the cryo-cooler thereby allowing the apparatus to reduce vibrations inherent in the operation of the cryo-cooler.
