    Abstract: Catheters including guidewire tubes having a limited length and methods of using the catheters are described. The catheters may be delivered over guidewires in procedures that are commonly referred to as rapid-exchange delivery. In some embodiments, the catheters may be miniature flexible thrombectomy catheters that may be used to remove thrombus or other unwanted material from a body blood vessel or other small regions of body cavities in which the distal portion of the catheter has smaller external dimensions than the larger proximal portion

    Abstract: A thrombectomy catheter includes a catheter body having a catheter lumen. An outflow orifice is positioned along a catheter perimeter. A fluid jet emanator communicates with a high pressure tube. The fluid jet emanator includes at least one jet orifice for directing a fluid jet from the fluid jet emanator through the catheter lumen toward the outflow orifice. The fluid jet emanator provides a jet stream from the catheter body through the outflow orifice. The jet stream includes first and second stream portions. An entrainment fluid flow circuit includes at least the first stream portion, and the entrainment fluid flow circuit entrains particulate and macerates the particulate therein. An exhaust fluid flow path includes the second stream portion, and the exhaust fluid flow path draws entrained particulate from the entrainment fluid flow circuit at a location exterior to the catheter body and directs it toward the catheter proximal portion.

    Abstract: A catheter assembly includes an inner mandrel and an outer sheath slidably coupled along the inner mandrel. The catheter assembly includes a scrubbing assembly coupled between the inner mandrel and the outer sheath. The scrubbing assembly includes a plurality of deformable struts deflectable according to movement of the inner mandrel relative to the outer sheath. The scrubbing assembly includes a proximal shoulder coupled with the outer sheath, and a distal shoulder coupled with the inner mandrel. The plurality of struts extend between the proximal and distal shoulders. The scrubbing assembly is movable between a stored configuration and a deployed configuration according to movement of the inner mandrel relative to the outer sheath. In the stored configuration the proximal and distal shoulders are remote from each other. In the deployed configuration the proximal shoulder is engaged with the distal shoulder, and the deformable struts are deflected into bristles.
