    摘要: 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.

    摘要: An atherectomy catheter is provided for excising and imaging material in a body lumen. In one embodiment, the catheter comprises a catheter body, a cutting blade, and an imaging device. The cutting blade is mounted on the catheter body and configured to move between a first position and a second position relative to an aperture or cutting window. When the cutting blade is in the second position, the blade substantially closes the aperture on the catheter body. The imaging device which is mounted on or otherwise coupled to the cutting blade is configured to be in an imaging position when the cutting blade substantially closes the aperture or cutter window. This allows the imaging device to survey material within the cutting zone of the atherectomy catheter. By allowing the imaging device to view materials within this cutting zone, material may be imaged and then removed from the body lumen without having to reposition the catheter between each step.
