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: An infusion system includes a double action infusion pump. The pump includes a cylinder and a reciprocating piston received within the cylinder, the reciprocating piston separating a first pump chamber from a second pump chamber of the cylinder. A reciprocating motor is coupled with the reciprocating piston, and the first and second pump chambers alternate between filling and evacuating conditions with reciprocation of the reciprocating piston through operation of the reciprocating motor, and the speed of reciprocation is varied to provide a continuous output of fluid between the first and second pump chambers. A fluid source and a catheter are optionally coupled with the double action infusion pump. The catheter includes one or more infusion ports near a catheter distal portion, and the one or more infusion ports receive and expel the continuous output of fluid from the double action infusion pump.

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.

Abstract: A catheter assembly includes a catheter body having a catheter lumen. A manifold assembly is coupled with a proximal catheter portion. A manifold lumen extends through the manifold assembly, and the manifold lumen includes an assembly cavity extending around the proximal catheter portion. A fluid jet loop is coupled with a high pressure tube at a distal catheter portion. The catheter assembly further includes a tapered loop guide surface.
