摘要：
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.
